2023-07-11configure: Fix cross-building for RISCV hostPhilippe Mathieu-Daudé1-1/+5
While when building on native Linux the host architecture is reported as "riscv32" or "riscv64": Host machine cpu family: riscv64 Host machine cpu: riscv64 Found pkg-config: /usr/bin/pkg-config (0.29.2) Since commit ba0e733362 ("configure: Merge riscv32 and riscv64 host architectures"), when cross-compiling it is detected as "riscv". Meson handles the cross-detection but displays a warning: WARNING: Unknown CPU family riscv, please report this at https://github.com/mesonbuild/meson/issues/new Host machine cpu family: riscv Host machine cpu: riscv Target machine cpu family: riscv Target machine cpu: riscv Found pkg-config: /usr/bin/riscv64-linux-gnu-pkg-config (1.8.1) Now since commit 278c1bcef5 ("target/riscv: Only unify 'riscv32/64' -> 'riscv' for host cpu in meson") Meson expects the cpu to be in [riscv32, riscv64]. So when cross-building (for example on our cross-riscv64-system Gitlab-CI job) we get: WARNING: Unknown CPU family riscv, please report this at https://github.com/mesonbuild/meson/issues/new Host machine cpu family: riscv Host machine cpu: riscv Target machine cpu family: riscv Target machine cpu: riscv ../meson.build:684:6: ERROR: Problem encountered: Unsupported CPU riscv, try --enable-tcg-interpreter Fix by partially revert commit ba0e733362 so when cross-building the ./configure script passes the proper host architecture to meson.

2023-06-26git-submodule.sh: allow running in validate mode without previous updatePaolo Bonzini1-1/+1
The call to git-submodule.sh done in configure may happen without a previous checkout of the roms/SLOF submodule, or even without a previous run of the script. So, handle creating a .git-submodule-status file even in validate mode. If git is absent, ensure that all passed directories exists (because you should be in a fresh untar and will not have stale arguments to git-submodule.sh) but do no other checks. If git is present, ensure that .git-submodule-status contains an entry for all submodules passed on the command line. With this change, "ignore" mode is not needed anymore. Reported-by: Nina Schoetterl-Glausch <nsg@linux.ibm.com> Fixes: b11f9bd96f4 ("configure: move SLOF submodule handling to pc-bios/s390-ccw", 2023-06-06) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-06-26build: further refine build.ninja rulesPaolo Bonzini1-0/+1
In commit b0fcc6fc7fc1 ("build: rebuild build.ninja using "meson setup --reconfigure"", 2023-05-19) I changed the build.ninja rule in the Makefile to use "meson setup" so that the Makefile would pick up a changed path to the meson binary. However, there was a reason why build.ninja was rebuilt using $(NINJA) itself. Namely, ninja has its own cache of file modification times, and if it does not know about the modification that was done outside its control, it will *also* try to regenerate build.ninja. This can be simply by running "make" on a fresh tree immediately after "configure"; that will trigger an unnecessary meson run. So, apply a refinement to the rule in order to cover both cases: - track the meson binary that was used (and that is embedded in build.ninja's reconfigure rules); to do this, write build.ninja.stamp right after executing meson successfully - if it changed, force usage of "$(MESON) setup --reconfigure" to update the path in the reconfigure rule - if it didn't change, use "$(NINJA) build.ninja" just like before commit b0fcc6fc7fc1.

If configure was invoked with --disable-download and git submodules were not checked out a warning is produced and the configure script fails. But the $download variable (which reflects the enable/disable download argument) is checked for in a weird fashion: test -f "$download" = disabled Drop the '-f' to check for the actual value of the variable.

2023-06-06meson: subprojects: replace berkeley-{soft,test}float-3 with wrapsPaolo Bonzini1-27/+0
Unlike other subprojects, these require an overlay directory to include meson rules to build the libraries. The rules are basically lifted from tests/fp/meson.build, with a few changes to create platform.h and publish a dependency. The build defines are passed through a subproject option, and posted back to users of the library via the dependency's compile_args. The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION is roms/SLOF, which is used to build pc-bios/s390-ccw.

2023-06-06meson: subprojects: replace submodules with wrap filesPaolo Bonzini1-45/+32
Compared to submodules, .wrap files have several advantages: * option parsing and downloading is delegated to meson * the commit is stored in a text file instead of a magic entry in the git tree object * we could stop shipping external dependencies that are only used as a fallback, but not break compilation on platforms that lack them. For example it may make sense to download dtc at build time, controlled by --enable-download, even when building from a tarball. Right now, this patch does the opposite: make-release treats dtc like libvfio-user (which is not stable API and therefore hasn't found its way into any distros) and keycodemap (which is a copylib, for better or worse). dependency() can fall back to a wrap automatically. However, this is only possible for libraries that come with a .pc file, and this is not very common for libfdt even though the upstream project in principle provides it; it also removes the control that we provide with --enable-fdt={system,internal}. Therefore, the logic to pick system vs. internal libfdt is left untouched. --enable-fdt=git is removed; it was already a synonym for --enable-fdt=internal. Reviewed-by: Daniel P.

2023-06-06configure: rename --enable-pypi to --enable-download, control subprojects tooPaolo Bonzini1-10/+7
The behavior of --{enable,disable}-pypi is similar to that of -Dwrapmode={default,nodownload} respectively. In particular, in both cases a feature needs to be explicitly enabled for the dependency to be downloaded. So, use a single option to control both cases. Now, --enable-slirp will trigger cloning and building of libslirp if the .pc file is not found on the machine. Reviewed-by: Daniel P.

2023-06-06configure: remove --with-git= optionPaolo Bonzini1-6/+2
The scenario for which --with-git= was introduced was to use a SOCKS proxy such as tsocks. However, this was back in 2017 when QEMU's submodules used the git:// protocol, and it is not as important when using the "smart HTTP" backend; for example, neither "meson subprojects download" nor scripts/checkpatch.pl obey the GIT environment variable. So remove the knob, but test for the presence of git in the configure and git-submodule.sh scripts, and suggest using --with-git-submodules=validate + a manual invocation of git-submodule.sh when git does not work. Hopefully in the future the GIT environment variable will be supported by Meson.

Apart from CLICOLOR_FORCE and GREP_OPTIONS, there are other variables that are listed in the Autoconf manual. While Autoconf neutralizes them very early, and assumes it does not (yet) run in a shell that has "unset", QEMU assumes that the user invoked configure under a POSIX shell, and therefore can simply use "unset" to clear them. CDPATH is particularly nasty because it messes up "cd ... && pwd". Reported-by: Juan Quintela <quintela@redhat.com> Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

QEMU adds the path to glib.h to all compilation commands. This is simpler due to the pervasive use of static_library, and was grandfathered in from the previous Make-based build system. Until Meson 0.63 the only way to do this was to detect glib in configure and use add_project_arguments, but now it is possible to use add_project_dependencies instead. gmodule is detected in a separate variable, with export enabled for modules and disabled for plugin.

2023-05-18configure: Add courtesy hint to Python version failure messageJohn Snow1-1/+4
If we begin requiring Python 3.7+, a few platforms are going to need to install an additional Python interpreter package. As a courtesy to the user, suggest the optional package they might need to install. This will hopefully minimize any downtime caused by the change in Python dependency.

2023-05-18Python: Drop support for Python 3.6Paolo Bonzini1-5/+5
Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have begun dropping support for this version and it is becoming more cumbersome to support. Avocado-framework and qemu.qmp each have their own reasons for wanting to drop Python 3.6, but won't until QEMU does. Versions of Python available in our supported build platforms as of today, with optional versions available in parentheses: openSUSE Leap 15.4: 3.6.15 (3.9.10, 3.10.2) CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16) CentOS Stream 9: 3.9.13 Fedora 36: 3.10 Fedora 37: 3.11 Debian 11: 3.9.2 Alpine 3.14, 3.15: 3.9.16 Alpine 3.16, 3.17: 3.10.10 Ubuntu 20.04 LTS: 3.8.10 Ubuntu 22.04 LTS: 3.10.4 NetBSD 9.3: 3.9.13* FreeBSD 12.4: 3.9.16 FreeBSD 13.1: 3.9.16 OpenBSD 7.2: 3.9.16 Note: Our VM tests install 3.9 explicitly for FreeBSD and 3.10 for NetBSD; the default for "python" or "python3" in FreeBSD is 3.9.16. NetBSD does not appear to have a default meta-package, but offers several options, the lowest of which is 3.7.15. "python39" appears to be a pre-requisite to one of the other packages we request in tests/vm/netbsd. pip, ensurepip and other Python essentials are currently only available for Python 3.10 for NetBSD. CentOS and OpenSUSE support parallel installation of multiple Python interpreters, and binaries in /usr/bin will always use Python 3.6. However, the newly introduced support for virtual environments ensures that all build steps that execute QEMU Python code use a single interpreter. Since it is safe to under our supported platform policy, bump our minimum supported version of Python to 3.7. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Daniel P.

2023-05-18configure: add --enable-pypi and --disable-pypiJohn Snow1-1/+20
In the event that there's no vendored source present and no sufficient version of $package can be found, we will attempt to connect to PyPI to install the package if '--disable-pypi' was not passed. This means that PyPI access is "enabled by default", but there are some subtleties that make this action occur much less frequently than you might imagine: (1) While --enable-pypi is the default, vendored source will always be preferred when found, making PyPI a fallback. This should ensure that configure-time venv building "just works" for almost everyone in almost every circumstance. (2) Because meson source is, at time of writing, vendored directly into qemu.git, PyPI will never be used for sourcing meson. (3) Because Sphinx is an optional dependency, if docs are set to "auto", PyPI will not be used to obtain Sphinx source as a fallback and instead docs will be disabled. If PyPI sourcing of sphinx is desired, --enable-docs should be passed to force the lookup. I chose this as the default behavior to avoid adding new internet lookups to a "default" invocation of configure.

2023-05-18configure: use 'mkvenv ensure meson' to bootstrap mesonJohn Snow1-54/+11
This commit changes how we detect and install meson. It notably removes '--meson='. Currently, configure creates a lightweight Python virtual environment unconditionally using the user's configured $python that inherits system packages. Temporarily, we forced the use of meson source present via git submodule or in the release tarball. With this patch, we restore the ability to use a system-provided meson: If Meson is installed in the build venv and meets our minimum version requirements, we will use that Meson. This includes a system provided meson, which would be visible via system-site packages inside the venv. In the event that Meson is installed but *not for the chosen Python interpreter*, not found, or of insufficient version, we will attempt to install Meson from vendored source into the newly created Python virtual environment. This vendored installation replaces both the git submodule and tarball source mechanisms for sourcing meson. As a result of this patch, the Python interpreter we use for both our own build scripts *and* Meson extensions are always known to be the exact same Python. As a further benefit, there will also be a symlink available in the build directory that points to the correct, configured python and can be used by e.g. manual tests to invoke the correct, configured Python unambiguously.

2023-04-20configure: Honour cross-prefix when finding ObjC compilerPeter Maydell1-8/+18
Currently when configure picks an ObjectiveC compiler it doesn't pay attention to the cross-prefix. This isn't a big deal in practice, because we only use ObjC on macos and you can't cross-compile to macos. But it's a bit inconsistent. Rearrange the handling of objcc in configure so that we do the same thing that we do with cc and cxx. This means that the logic for picking the ObjC compiler goes from: if --objcc is specified, use that otherwise if clang is available, use that otherwise use $cc to: if --objcc is specified, use that otherwise if --cross-prefix is specified, use ${cross_prefix}clang otherwise if clang is available, use that otherwise use $cc Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1185 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20230418161554.744834-1-peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
