2024-06-08Revert "python: use vendored tomli"Paolo Bonzini
Now that Ubuntu 20.04 is not included anymore, there is no need to ship it as part of QEMU; Ubuntu 22.04 includes it and Leap users anyway need to install all the required dependencies from PyPI. This mostly reverts commit ec77ee7634de123b7c899739711000fd21dab68b, with just some changes to the wording. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-05-24configure: move -mcx16 flag out of CPU_CFLAGSArtyom Kunakovsky
The point of CPU_CFLAGS is really just to select the appropriate multilib, for example for library linking tests, and -mcx16 is not needed for that purpose. Furthermore, if -mcx16 is part of QEMU's choice of a basic x86_64 instruction set, it should be applied to cross-compiled x86_64 code too; it is plausible that tests/tcg would want to cover cmpxchg16b as well, for example. In the end this makes just as much sense as a per sub-build tweak, so move the flag to meson.build and cross_cc_cflags_x86_64. This leaves out contrib/plugins, which would fail when attempting to use __sync_val_compare_and_swap_16 (note it does not do yet); while minor, this *is* a disadvantage of this change. But building contrib/plugins with a Makefile instead of meson.build is something self-inflicted just for the sake of showing that it can be done, and if this kind of papercut started becoming a problem we could make the directory part of the meson build. Until then, we can live with the limitation.

2024-05-14configure: Fix error message when C compiler is not workingThomas Huth
If you try to run the configure script on a system without a working C compiler, you get a very misleading error message: ERROR: Unrecognized host OS (uname -s reports 'Linux') Some people already opened bug tickets because of this problem: https://gitlab.com/qemu-project/qemu/-/issues/2057 https://gitlab.com/qemu-project/qemu/-/issues/2288 We should rather tell the user that we were not able to use the C compiler instead, otherwise they will have a hard time to figure out what was going wrong. While we're at it, let's also suppress the "unrecognized host CPU" message in this case since it is rather misleading than helpful.

2024-05-10configure: quote -D options that are passed through to mesonPaolo Bonzini
Ensure that they go through unmodified, instead of removing one layer of quoting. -D is a pretty specialized option and most options that can have spaces do not need it (for example, c_args is covered by --extra-cflags). Therefore it's unlikely that this causes actual trouble. However, a somewhat realistic failure case would be with -Dpkg_config_path and a pkg-config directory that contains spaces.

Commit c2118e9e1ab ("configure: don't try a "native" cross for linux-user", 2023-11-23) sought to avoid issues with using the native compiler with a cross-endian or cross-bitness setup. However, in doing so it ended up requiring a cross compiler setup (and most likely a slow compiler setup) even when building TCG tests that are native to the host architecture. Always allow the host compiler in that case.

2023-10-18configure: define "pkg-config" in addition to "pkgconfig"Paolo Bonzini
Meson used to allow both "pkgconfig" and "pkg-config" entries in machine files; the former was used for dependency lookup and the latter was used as return value for "find_program('pkg-config')", which is a less common use-case and one that QEMU does not need. This inconsistency is going to be fixed by Meson 1.3, which will deprecate "pkgconfig" in favor of "pkg-config" (the less common one, but it makes sense because it matches the name of the binary). For backward compatibility it is still allowed to define both, so do that in the configure-generated machine file.

2023-09-07Python: Drop support for Python 3.7Paolo Bonzini
Debian 10 is not anymore a supported distro, since Debian 12 was released on June 10, 2023. Our supported build platforms as of today all support at least 3.8 (and all of them except for Ubuntu 20.04 support 3.9): openSUSE Leap 15.5: 3.6.15 (3.11.2) CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16, 3.11.4) CentOS Stream 9: 3.9.17 (3.11.4) Fedora 37: 3.11.4 Fedora 38: 3.11.4 Debian 11: 3.9.2 Debian 12: 3.11.2 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: 3.10.12 NetBSD 9.3: 3.9.13* FreeBSD 12.4: 3.9.16 FreeBSD 13.1: 3.9.18 OpenBSD 7.2: 3.9.17 Note: NetBSD does not appear to have a default meta-package, but offers several options, the lowest of which is 3.7.15. However, "python39" appears to be a pre-requisite to one of the other packages we request in tests/vm/netbsd. Since it is safe under our supported platform policy, bump our minimum supported version of Python to 3.8. The two most interesting features to have by default include: - the importlib.metadata module, whose lack is responsible for over 100 lines of code in mkvenv.py - improvements to asyncio, for example asyncio.CancelledError inherits from BaseException rather than Exception In addition, code can now use the assignment operator ':=' Because mypy now learns about importlib.metadata, a small change to mkvenv.py is needed to pass type checking.
