2021-06-12sim: overhaul alignment settings managementMike Frysinger4-56/+8
Currently, the sim-config module will abort if alignment settings haven't been specified by the port's configure.ac. This is a bit weird when we've allowed SIM_AC_OPTION_ALIGNMENT to seem like it's optional to use. Thus everyone invokes it. There are 4 alignment settings, but really only 2 matters: strict and nonstrict. The "mixed" setting is just the default ("unset"), and "forced" isn't used directly by anyone (it's available as a runtime option for some ports). The m4 macro has 2 args: the "wire" settings (which represents the hardwired port behavior), and the default settings (which are used if nothing else is specified). If none are specified, then the build won't work (see above as if SIM_AC_OPTION_ALIGNMENT wasn't called). If default settings are provided, then that is used, but we allow the user to override at runtime. Otherwise, the "wire" settings are used and user runtime options to change are ignored. Most ports specify a default, or set the "wire" to nonstrict. A few set "wire" to strict, but it's not clear that's necessary as it doesn't make the code behavior, by default, any different. It might make things a little faster, but we should provide the user the choice of the compromises to make: force a specific mode at compile time for faster runtime, or allow the choice at runtime. More likely it seems like an oversight when these ports were initially created, and/or copied & pasted from existing ports. With all that backstory, let's get to what this commit does. First kill off the idea of a compile-time default alignment and set it to nonstrict in the common code. For any ports that want strict alignment by default, that code is moved to sim_open while initializing the sim. That means WITH_DEFAULT_ALIGNMENT can be completely removed. Moving the default alignment to the runtime also allows removal of setting the "wire" settings at configure time. Which allows removing of all arguments to SIM_AC_OPTION_ALIGNMENT and moving that call to common code. The macro logic can be reworked to not pass WITH_ALIGNMENT as -D CPPFLAG and instead move it to config.h. All of these taken together mean we can hoist the macro up to the top level and share it among all sims so behavior is consistent among all the ports.
2021-06-12sim: unify bug & package settingsMike Frysinger3-87/+2
Move these options up to the common dir so we only test & export them once across all ports. The AC_INIT macro does a lot of the heavy lifting already which allows further simplification.
2021-06-12sim: unify debug/stdio/trace/profile build settingsMike Frysinger2-150/+2
Move these options up to the common dir so we only test & export them once across all ports. The ppc code needs a little extra care with its trace settings as it's not exactly the same API as the common code. The other knobs are the same though.
2021-06-12sim: unify environment build settingsMike Frysinger3-32/+2
Move the --sim-enable-environment option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify assert build settingsMike Frysinger4-28/+6
Move the --sim-enable-assert option up to the common dir so we only test & export it once across all ports.
2021-06-12sim: unify platform function & header testsMike Frysinger4-594/+8
Move the various platform tests up a level to avoid duplication across the ports. When building multiple versions, this speeds things up a bit. For now we move the obvious stuff up a level, but we don't turn own the config.h entirely just yet -- we still have some tests related to libraries that need consideration.
2021-06-08sim: igen: harmonize tool variablesMike Frysinger2-2/+7
Separate the name of the igen program from the options used to run it. This allows us to avoid duplicating ../igen/igen in Makefiles and reuse the existing setting in the common Makefile. This also allows us to easily harmonize the use of EXEEXT between igen/local.mk and the common makefiles when cross-compiling for e.g. Windows.
2021-06-08sim: v850: assume chown is availableMike Frysinger5-11/+9
Now that gnulib provides a wrapper, assume it always exists.
2021-05-29sim: v850: add pointer casts for execv on WindowsMike Frysinger2-2/+6
The execv prototypes on Windows via mingw64 include extra const markings on the argv/envp pointers than what POSIX specifies. Cast them to void* as a hack to get it working on all platforms.
2021-05-17sim: fully merge sim_state_base into sim_stateMike Frysinger2-2/+4
Now that all ports have migrated to the new framework, drop support for the old sim_state_base layout.
2021-05-17sim: invert sim_state storageMike Frysinger2-12/+7
Currently all ports have to declare sim_state themselves in their sim-main.h and then embed the common sim_state_base & sim_cpu in it. This dynamic makes it impossible to share common object code among multiple ports because the core data structure is always different. Let's invert this relationship: common code declares sim_state, and if the port actually needs state on a per-instance basis, it can use the new arch_data field for it. Most ports don't actually use it, so they don't need to declare anything at all. This is the first in a series of changes: it adds a define to select between the old & new layouts, then converts all the ports that don't need custom state over to the new layout.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger4-1/+11
The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise.
2021-05-16sim: riscv: move __int128 check to configureMike Frysinger3-2/+19
2021-05-04sim: add support for build-time ar & ranlibMike Frysinger2-2/+14
This is needed when building for a target whose ar & ranlib are incompatible with the current build system. For example, building for Windows on a Linux system. Then manually import the automake rule for libigen.a, but tweak the tool variables to use the FOR_BUILD variants.
2021-05-03sim: add ATTRIBUTE_PRINTF / ATTRIBUTE_NULL_PRINTF where necessarySimon Marchi2-2/+6
I finally got the all-targets sim building with Clang, these are all the instances where an ATTRIBUTE_PRINTF or ATTRIBUTE_NULL_PRINTF attribute needed to be added to avoid errors like: /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-profile.c:464:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral] vfprintf (fp, fmt, ap); ^~~ There are more fixes needed to get everything building, but adding these attributes is trivial enough, so I send them all in a single patch. Adding the format attributes introduces some format string errors when building with GCC (because now format strings are checked), so corresponding changes are needed to avoid breaking the build. Other than simple format string specified changes, there is this one: /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c: In function 'hw_event_queue_schedule': /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c:95:15: error: too many arguments for format [-Werror=format-extra-args] 95 | NULL, dummy); | ^~~~~ We can fix it and avoid using a dummy variable by simply calling hw_event_queue_schedule_tracef instead of hw_event_queue_schedule_vtracef. sim/arm/ChangeLog: * armdefs.h (ARMul_ConsolePrint): Use format attribute. * wrapper.c (op_printf): Likewise. sim/bfin/ChangeLog: * interp.c (sim_open): Adjust format string specifier. sim/common/ChangeLog: * hw-events.h (hw_event_queue_schedule_tracef): Use format attribute.

2021-05-01sim: nrun: add local strsignal prototypeMike Frysinger3-2/+12
While libiberty provides a definition for this for systems that lack the function (e.g. Windows), it doesn't provide a prototype. So add our own local copy in the one file that uses the func.
2021-04-26sim: enable hardware support by defaultMike Frysinger4-5/+120
Force this on for all ports. We have a few common models that can be used, so make them generally available. If the port doesn't use any hardware (the default), then behavior is unchanged.
2021-04-22Do not check for sys/time.h or sys/times.hTom Tromey3-14/+6
This updates the sim so that it unconditionally uses sys/time.h. This is in agreement with existing code, and a recent change to BFD. I also think that sys/times.h is never needed by the sim, so this patch removes the check and the one spot that was conditionally including it. sim/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * m4/sim_ac_common.m4 (SIM_AC_COMMON): Don't check for sys/time.h or sys/times.h. sim/aarch64/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/arm/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/avr/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bfin/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/bpf/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/common/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * sim-utils.c: Update includes. sim/cr16/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * simops.c: Update includes. * configure, config.in: Rebuild. sim/cris/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * rvdummy.c: Update includes. * dv-rv.c: Update includes. * configure, config.in: Rebuild. sim/d10v/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/erc32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/example-synacor/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/frv/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ft32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/h8300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/iq2000/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/lm32/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32c/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m32r/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/m68hc11/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mcore/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/microblaze/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mips/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/mn10300/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/moxie/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/msp430/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/or1k/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * configure, config.in: Rebuild. sim/ppc/ChangeLog 2021-04-22 Tom Tromey <tom@tromey.com> * mon.c: Update includes. * emul_unix.c: Update includes.

2021-04-21sim: use -Werror when probing for supported warning flagsSimon Marchi2-1/+5
When building with clang, we get: error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option] This is because clang only warns by default when encountering an unknown warning option, and the probe for supported warning flags is done without -Werror. All flags are therefore accepted by configure, but then it breaks when actually compiling a source file with -Werror. This is equivalent to this commit in gdb: 3e019bdc20eb81b91ab5bc774386201b874c0bac gdb: Use -Werror when checking for (un)supported warning flags We then see some other compilation errors when building with clang and -Werror, they can be dealt with later.

This avoids duplicate tests for headers between common m4, arches, and any other sources that would trigger header tests.
2021-04-18sim: switch to AC_CHECK_FUNCS_ONCE & merge a littleMike Frysinger3-36/+72
This avoids duplicate tests for functions between common m4, arches, and any other sources that would trigger func tests. Also manually delete known duplicate function tests between the m4, bfin, and v850 ports.
2021-04-12sim: cgen: move cgen_cpu_max_extra_bytes logic into the common codeMike Frysinger2-1/+5
Every arch handles this the same way, so move it to the common code. This will also make unifying the sim_cpu structure easier.
2021-04-08sim: set ASAN_OPTIONS=detect_leaks=0 when running igen and opc2cSimon Marchi2-1/+5
The igen/dgen and opc2c tools leak their heap-allocated memory (on purpose) at program exit, which makes AddressSanitizer fail the tool execution. This breaks the build, as it makes the tool return a non-zero exit code. Fix that by disabling leak detection through the setting of that environment variable. I also changed the opc2c rules for m32c to go through a temporary file. What happened is that the failing opc2c would produce an incomplete file (probably because ASan exits the process before stdout is flushed). This meant that further make attempts didn't try to re-create the file, as it already existed. A "clean" was therefore necessary. This can also happen in regular builds if the user interrupts the build (^C) in the middle of the opc2c execution and tries to resume it. Going to a temporary file avoids this issue. sim/m32c/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running opc2c. sim/mips/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/mn10300/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/ppc/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen. sim/v850/ChangeLog: * Makefile.in: Set ASAN_OPTIONS when running igen.

2021-04-02sim: igen: merge build into top levelMike Frysinger2-4/+5
This simplifies the build a bit (especially for deps in port subdirs), and avoids recursive make. This in turn speeds up the build, and sets us up for multi-target.
2021-04-02sim: unify toolchain settingsMike Frysinger3-153/+162
The toplevel, common, and igen dirs all have their own code for setting up toolchain settings. Unify all of that in a new macro.
2021-02-28sim: set up build-time compiler settingsMike Frysinger1-9/+10
Some sim dirs were already setting up CFLAGS_FOR_BUILD in inconsistent ways. Move it to a common place for reuse.
2021-02-28sim: use AC_CHECK_TOOL to find arMike Frysinger1-3/+93
Rather than require $AR be set and then default to `ar`, use the standard AC_CHECK_TOOL helper to find a good prefixed tool. In practice this shouldn't change much as we seem to have macros in the tree that were already setting it up, but we shouldn't rely on that implicitly.
2021-02-28sim: require AC_PROG_CPP explicitlyMike Frysinger2-140/+145
All the scripts were using this implicitly already, so there's no real change for them, but we want to call it explicitly as the CPP tool is used to generate nltvals.def.
2021-02-21sim: common: split up acinclude.m4 into individual m4 filesMike Frysinger4-9/+34
This file is quite large and is getting unmanageable. Split it apart to follow aclocal best practices by putting one-macro-per-file. There shouldn't be any real functional changes here as can be seen in the configure script regens.
2021-02-13sim: switch to AC_CONFIG_MACRO_DIRSMike Frysinger4-1834/+35
Rather than hand maintain m4 includes in various autotool files, use AC_CONFIG_MACRO_DIRS to declare the relevant search paths. This simplifies the code, makes it more robust, and cleans out unused logic from configure.
2021-02-06sim: watchpoints: use common sim_pc_getMike Frysinger2-1/+4
Few arches implement STATE_WATCHPOINTS()->pc while all of them implement sim_pc_get. Lets switch the sim-watch core for monitoring pc events to the sim_pc_get API so this module works for all ports, and then we can delete this old back channel of snooping in the port's cpu state -- the code needs the pointer to the pc storage so that it can read out bytes and compare them to the watchrange. This also fixes the logic on multi-cpu sims by removing the limitation of only being able to watch CPU0's state.
2021-02-06sim: common: switch AC_CONFIG_HEADERSMike Frysinger1-3/+2
The AC_CONFIG_HEADER macro is long deprecated, so switch to the newer form. This also gets rid of the position limitation, and drops support for an argument to SIM_AC_COMMON which we haven't used anywhere.
2021-02-06sim: drop use of bfd/configure.hostMike Frysinger2-6/+6
These settings might have made sense in darker compiler times, but I think they're largely obsolete now. Looking through the values that get used in HDEFINES, it's quite limited, and configure itself should handle them. If we still need something, we can leverage standard autoconf macros instead, after we get a clear user report. TDEFINES was never set anywhere and was always empty, so prune that.
2021-01-31sim: v850: cleanup build warningsMike Frysinger4-107/+124
This port only had one minor warning left in it, so fix it and then enable -Werror behavior by deleting the macro call. We'll use the common default now (which is -Werror).
2021-01-31sim: v850: fix handling of SYS_timesMike Frysinger2-2/+5
My recent rewrite of the nltvals generator fixed a bug where SYS_times was not being exported for v850. But that in turn uncovered this bug where the SYS_times codepath had a compile error.
2021-01-30sim: watchpoints: change sizeof_pc to sizeof(sim_cia)Mike Frysinger2-1/+4
Existing ports already have sizeof_pc set to the same size as sim_cia, so simply make that part of the core code. We already assume this in places by way of sim_pc_{get,set}, and this is how it's documented in the sim-base.h API. There is code to allow sims to pick different register word sizes from address sizes, but most ports use the defaults for both (32-bits), and the few that support multiple register sizes never change the address size (so address defaults to register). I can't think of any machine where the register hardware size would be larger than the address word size either. We have ABIs that behave that way (e.g. x32), but the hardware is still equivalent register sized.
2021-01-11sim: clean up C11 header includesMike Frysinger5-36/+37
Since we require C11 now, we can assume many headers exist, and clean up all of the conditional includes. It's not like any of this code actually accounted for the headers not existing, just whether we could include them. The strings.h cleanup is a little nuanced: it isn't in C11, but every use of it in the codebase will include strings.h only if string.h doesn't exist. Since we now assume the C11 string.h exists, we'll never include strings.h, so we can delete it.
2021-01-09sim: clean up stale AC_PREREQ refsMike Frysinger2-14/+7
This was purged from the tree when we upgraded to autoconf-2.69, but a few references in the sim tree were missed.
2021-01-09sim: enable -Werror by default for some archesMike Frysinger3-6/+6
We've had this off for a long time because the sim code was way too full of warnings for it to be feasible. However, I've cleaned things up significantly from when this was first merged, and we can start to turn this around. Change the macro to enable -Werror by default, and allow ports to opt out. New ports will get it automatically (and we can push back on them if they try to turn it off). Also turn it off for the few ports that still hit warnings for me. All the rest will get the new default, and we'll wait for feedback if/when new issues come up.
2021-01-08sim: require a C11 compilerMike Frysinger2-13/+57
With GDB requiring a C++11 compiler now, this hopefully shouldn't be a big deal. It's been 10 years since C11 came out, so should be plenty of time to upgrade. This will allow us to start cleaning up random header logic and many of our non-standard custom types.

gdb/ChangeLog: Update copyright year range in all GDB files.
2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi4-554/+604
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see: configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation Solution 1: Adjust the code based on the example at that URL. Problem 2 (in zlib/): Makefile.am: error: required file './INSTALL' not found Makefile.am: 'automake --add-missing' can install 'INSTALL' Makefile.am: error: required file './NEWS' not found Makefile.am: error: required file './AUTHORS' not found Makefile.am: error: required file './COPYING' not found Makefile.am: 'automake --add-missing' can install 'COPYING' Solution 2: Add the foreign option to AUTOMAKE_OPTIONS. Problem 3: doc/Makefile.am:20: error: support for Cygnus-style trees has been removed Solution 3: Remove the cygnus options. Problem 4: Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') Solution 4: Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is already defined earlier). Problem 5: doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 5: Rename .texinfo files to .texi. Problem 6: doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 6: Remove the hack at the bottom of doc/Makefile.am and use the info-in-builddir automake option. Problem 7: doc/Makefile.am:35: error: required file '../texinfo.tex' not found doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex' Solution 7: Use the no-texinfo.tex automake option. We also have one in texinfo/texinfo.tex, not sure if we should point to that, or move it (or a newer version of it added with automake --add-missing) to top-level. Problem 8: Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory, Makefile.am:131: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. Solution 8: Use subdir-objects, that means adjusting references to some .o that will now be in config/. Problem 9: configure.ac:375: warning: AC_LANG_CONFTEST: no AC_LANG_SOURCE call detected in body ../../lib/autoconf/lang.m4:193: AC_LANG_CONFTEST is expanded from... ../../lib/autoconf/general.m4:2601: _AC_COMPILE_IFELSE is expanded from... ../../lib/autoconf/general.m4:2617: AC_COMPILE_IFELSE is expanded from... ../../lib/m4sugar/m4sh.m4:639: AS_IF is expanded from... ../../lib/autoconf/general.m4:2042: AC_CACHE_VAL is expanded from... ../../lib/autoconf/general.m4:2063: AC_CACHE_CHECK is expanded from... configure.ac:375: the top level Solution 9: Use AC_LANG_SOURCE, or use proper quoting.
