It's often handy to make executables depend on each other, e.g. make a test depend on a helper. This doesn't work now, as linker will attempt to use the helper as an object. To fix, filter only relevant file types before linking an executable. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2015-08-13make: load only required dependency files.Victor Kaplansky1-1/+1
The old rules.mak loads dependency .d files using include directive with file glob pattern "*.d". This breaks the build when build tree has left-over *.d files from another build. This patch fixes this by - loading precise list of .d files made from *.o and *.mo. - specifying explicit list of required dependency info files for *.hex autogenerated sources. Note that Makefile still includes some .d in root directory by including "*.d". Signed-off-by: Victor Kaplansky <victork@redhat.com> Reviewed-by: Michael S.

2015-08-13make: fix where dependency *.d are stored.Victor Kaplansky1-1/+1
In rules like "bar/%.o: %.c" there is a difference between $(*D) and $(@D). $(*D) expands to '.', while $(@D) expands to 'bar'. It is cleaner to generate *.d in the same directory where appropriate *.o resides. This allows precise including of dependency info from .d files. As a hack, we also touch two sources for generated *.hex files. Without this hack, anyone doing "git pull; make" will not get *.hex rebuilt correctly since the dependency file would be missing.

2015-05-08rules.mak: Force CFLAGS for all objects in DSOFam Zheng1-1/+3
Because of the trick of process-archive-undefs, all .mo objects, even with --enable-modules, are dependencies of executables. This breaks CFLAGS propogation because the compiling of module object will happen too early before building for DSO. With GCC 5, the linking would fail because .o doesn't have -fPIC. Also, BUILD_DSO will be missed. (module-common.o will have it, so the stamp symbol was still liked in .so). Fix the problem by forcing the CFLAGS on individual .o-cflags during unnest-vars.

2015-01-14rules.mak: Fix module buildFam Zheng1-11/+12
Module build is broken since commit c261d774fb ( rules.mak: Fix DSO build by pulling in archive symbols). That commit added .mo placeholders of DSO to -y variables, in order to pull stub symbols to executable. But the placeholders are unintentionally expanded in -y, rather than filtered out while linking. Fix it by moving the -objs expanding to before inserting .mo placeholders. Note that passing -cflags and -libs to member objects are also moved to keep it happening before object expanding.

2014-09-09rules.mak: Fix DSO build by pulling in archive symbolsFam Zheng1-3/+40
This fixes an issue with module build system. block/iscsi.so is currently broken: $ ~/build/last/qemu-img Failed to open module: /home/fam/build/master/block-iscsi.so: undefined symbol: qmp_query_uuid qemu-img: Not enough arguments Try 'qemu-img --help' for more information To fix this, we should (at least) let qemu-img link qmp_query_uuid from libqemustub.a. (There are a few other symbols missing, as well.) This patch changes the linking rules to: 1) Build ".mo" with "ld -r -o $@ $^" for each ".so", and later build .so with it. 2) Always build all the .mo before linking the executables. This is achieved by adding those .mo files to the executables' "-y" variables. 3) When linking an executable, those .mo files in its "-y" variables are filtered out, and replaced by one or more -Wl,-u,$symbol flags. This is done in the added macro "process-archive-undefs". These "-Wl,-u,$symbol" flags will force ld to pull in the function definition from the archives when linking. Note that the .mo objects, that are actually meant to be linked in the executables, are already expanded in unnest-vars, before the linking command. So we are safe to simply filter out .mo for the purpose of pulling undefined symbols. process-archive-undefs works as this: For each ".mo", find all the undefined symbols in it, filter ones that are defined in the archives. For each of these symbols, generate a "-Wl,-u,$symbol" in the link command, and put them before archive names in the command line. Suggested-by: H.J.

2014-06-16rules.mak: remove $(sort) from extract-libsPaolo Bonzini1-1/+1
Duplicate removal was added to extract-libs in order to avoid including the same library multiple times into the linking command line; this could potentially happen when using "foo.mo-libs" (which adds the library to all components, causing it to appear N times if the module is composed of N objects). However, sorting and removing duplicates causes problems with static linking, and also with space-separated linker options as found in some Mac OS X packaging systems. Furthermore, the "optimization" is really a non-problem since we do not expect .mo modules to be composed of many files.

2014-06-10rules.mak: Rewrite unnest-varsFam Zheng1-79/+158
The macro unnest-vars is the most important, complicated but hard to track magic in QEMU's build system. Rewrite it in a (hopefully) clearer way, with more comments, to make it easier to understand and maintain. Remove DSO_CFLAGS and module-objs-m that are not used. A bonus fix of this version is, per object variables are properly protected in save-objs and load-objs, before including sub-dir Makefile.objs, just as nested variables are.

2014-02-20module: implement module loadingFam Zheng1-0/+3
This patch adds loading, stamp checking and initialization of modules. The init function of dynamic module is no longer directly called as __attribute__((constructor)) in static linked version, it is called only after passed the checking of presense of stamp symbol: qemu_stamp_$RELEASEHASH where $RELEASEHASH is generated by hashing version strings and content of configure script. With this, modules built from a different tree/version/configure will not be loaded. The module loading code requires gmodule-2.0. Modules are searched under - CONFIG_MODDIR - executable folder (to allow running qemu-{img,io} in the build directory) - ../ of executable folder (to allow running system emulator in the build directory) Modules are linked under their subdir respectively, then copied to top level of build directory for above convinience, e.g.: $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-02-20rules.mak: introduce DSO rulesFam Zheng1-9/+43
Add necessary rules and flags for shared object generation. The new rules introduced here are: 1) %.o in $(common-obj-m) is compiled to %.o, then linked to %.so. 2) %.mo in $(common-obj-m) is the placeholder for %.so for pattern matching in Makefile. It's linked to "-shared" with all its dependencies (multiple *.o) as input. Which means the list of depended objects must be specified in each sub-Makefile.objs: foo.mo-objs := bar.o baz.o qux.o in the same style with foo.o-cflags and foo.o-libs. The objects here will be prefixed with "$(obj)/" if it's a subdirectory Makefile.objs. 3) For all files ending up in %.so, the following is added automatically: foo.o-cflags += -fPIC -DBUILD_DSO Also introduce --enable-modules in configure, the option will enable support of shared object build. Otherwise objects are static linked to executables. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

This doesn't hurt compiling because we basically build all .o from top Makefile, before entering Makefile.target, but it will affact arriving per-object libs support.

2012-11-18build: replace weak symbols with a static libraryPaolo Bonzini1-1/+1
Weak symbols were a nice idea, but they turned out not to be a good one. Toolchain support is just too sparse, in particular llvm-gcc is totally broken. This patch uses a surprisingly low-tech approach: a static library. Symbols in a static library are always overridden by symbols in an object file. Furthermore, if you place each function in a separate source file, object files for unused functions will not be taken in. This means that each function can use all the dependencies that it needs (especially QAPI stuff such as error_setg). Thus, all stubs are placed in separate object files and put together in a static library. The library then is linked to all programs.

2012-08-16Support using a different compiler for Objective-C filesPeter Maydell1-1/+1
MacOSX 10.8 ("Mountain Lion") requires us to compile our one Objective-C source file with clang even if the rest of QEMU requires a real gcc, because the system headers we use make use of Apple's "Blocks" extension to C/ObjC, and mainline gcc doesn't support that. Since we only need to use a true gcc for the parts of QEMU that use the fixed-register env variable, we can simply use clang to build the ObjC file: it will link to the gcc-built objects with no problems. Add the necessary support for an OBJCC variable in the makefile and configure machinery; we default to clang if we have it, otherwise whatever CC is (since gcc might be the Apple gcc which does support Blocks).
