The argument of --host-cc is not obeyed when cross compiling. To avoid
this issue, place it in a configuration file and pass it to meson
with --native-file.
While at it, clarify that --host-cc is not obeyed anyway when _not_
cross compiling, because cc="$host_cc" is placed before --host-cc is

Using the new ensuregroup command, the desired versions of meson and
sphinx can be placed in pythondeps.toml rather than configure.
The meson.install entry in pythondeps.toml matches the version that is
found in python/wheels. This ensures that mkvenv.py uses the bundled
wheel even if PyPI is enabled; thus not introducing warnings or errors
from versions that are more recent than the one used in CI.
The sphinx entries match what is shipped in Fedora 38. It's the
last release that has support for older versions of Python (sphinx 6.0
requires Python 3.8) and especially docutils (of which sphinx 6.0 requires
version 0.18). This is important because Ubuntu 20.04 has docutils 0.14
and Debian 11 has docutils 0.16.

The CPU model has to be canonicalized to what Meson wants in the cross
file, to what Linux uses for its asm-$ARCH directories, and to what
QEMU uses for its user-mode emulation host/$ARCH directories. Do
all three in a single case statement, and check that the Linux and
QEMU directories actually exist.
At a small cost in repeated lines, this ensures that there are no hidden
ordering requirements between the case statements. In particular, commit
89e5b7935e ("configure: Fix linux-user host detection for riscv64",
2023-08-06) broke ppc64le because it assigned host_arch based on a

(because you should be in a fresh untar and will not have stale

In commit b0fcc6fc7f ("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 b0fcc6fc7f.

from tests/fp/meson.build, with a few changes to create platform.h

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

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.

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.

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".

Meson already knows to test with the positive form of the flag, which

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.

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.

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.

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

The configure script used to compile some code which dereferences memory
with ubsan to verify the compiler can link with ubsan library which
detects dereferencing of uninitialized memory. However, as the
dereferenced memory was allocated in the same code, GCC can statically
detect the unitialized memory dereference and emit maybe-uninitialized
warning. If -Werror is set, this becomes an error, and the configure
script incorrectly thinks the error indicates the compiler cannot use
ubsan.
Fix this error by replacing the code with another function which adds
1 to a signed integer argument. This brings in ubsan to detect if it
causes signed integer overflow. As the value of the argument cannot be
statically determined, the new function is also immune to compiler
warnings.

The following patches are going to introduce meson wrap dependencies,
which is a solution to download and build missing dependencies.
The QEMU build-system will do network access with no way to avoid the
fallback. As a start, hardcode "--wrap-mode=nodownload" in configure, so
that wraps would be used only after a conscious decision of the user to
use "meson subprojects download" (before running configure).

At the moment, we look for just "python3" and "python", which is good
enough almost all of the time. But ... if you are on a platform that
uses an older Python by default and only offers a newer Python as an
option, you'll have to specify --python=/usr/bin/foo every time.
We can be kind and instead make a cursory attempt to locate a suitable
Python binary ourselves, looking for the remaining well-known binaries.
This configure loop will prefer, in order:
1. Whatever is specified in $PYTHON
2. python3
3. python
4. python3.11 down through python3.6
Notes:
- Python virtual environment provides binaries for "python3", "python",
and whichever version you used to create the venv,
e.g. "python3.8". If configure is invoked from inside of a venv, this
configure loop will not "break out" of that venv unless that venv is
created using an explicitly non-suitable version of Python that we
cannot use.
- In the event that no suitable python is found, the first python found
is the version used to generate the human-readable error message.
- The error message isn't printed right away to allow later

If neither --python nor --meson are specified, Meson's generated
build.ninja will invoke Python script using the interpreter *that Meson
itself is running under*; not the one identified by configure.
This is only an issue if Meson's Python interpreter is not "the first
one in the path", which is the one that is used if --python is not
specified. A common case where this happen is when the "python3" binary
comes from a virtual environment but Meson is not installed (with pip)
in the virtual environment. In this case (presumably) whoever set up
the venv wanted to use the venv's Python interpreter to build QEMU,
while Meson might use a different one, for example an enterprise
distro's older runtime.
So, detect whether a virtual environment is setup, and if the virtual
environment does not have Meson, use the meson submodule. Meson will
then run under the virtual environment's Python interpreter.

Anthony Perard recently reported some problems with Clang v6.0 from
Ubuntu Bionic (with regards to the -Wmissing-braces configure test).
Since we're not officially supporting that version of Ubuntu anymore,
we should better bump our minimum version check in the configure script
instead of using our time to fix problems of unsupported compilers.
According to repology.org, our supported distros ship these versions
of Clang (looking at the highest version only):
Fedora 36: 14.0.5
CentOS 8 (RHEL-8): 12.0.1
Debian 11: 13.0.1
OpenSUSE Leap 15.4: 13.0.1
Ubuntu LTS 20.04: 12.0.0
FreeBSD Ports: 15.0.7
NetBSD pkgsrc: 15.0.7
Homebrew: 15.0.7
MSYS2 mingw: 15.0.7
Haiku ports: 12.0.1
While it seems like we could update to v12.0.0 from that point of view,
the default version on Ubuntu 20.04 is still v10.0, and we use that for
our CI tests based via the tests/docker/dockerfiles/ubuntu2004.docker
file.
Thus let's make v10.0 our minimum version now (which corresponds to
Apple Clang version v12.0). The -Wmissing-braces check can then be
removed, too, since both our minimum GCC and our minimum Clang version
now handle this correctly.

We've been very gradually adding G_GNUC_PRINTF annotations
to functions over years. This has been useful in detecting
certain malformed printf strings, or cases where we pass
user data as the printf format which is a potential security
flaw.
Given the inherant memory corruption danger in use of format
strings vs mis-matched variadic arguments, it is worth applying
G_GNUC_PRINTF to all functions using printf, even if we know
they are safe.
The compilers can reasonably reliably identify such places
with the -Wsuggest-attribute=format / -Wmissing-format-attribute
flags.

Some warnings are hardcoded in QEMU_CFLAGS and not tested. There is
no particular reason to single out these five, as many more -W flags are
present on all the supported compilers. For homogeneity when moving

After configuring with --target-list=hexagon-linux-user
running `make check-tcg` just prints the following:
```
make: Nothing to be done for 'check-tcg'
```
In the probe_target_compiler function, the 'break'
command is used incorrectly. There are no lexically
enclosing loops associated with that break command which
is an unspecfied behaviour in the POSIX standard.
The dash shell implementation aborts the currently executing
loop, in this case, causing the rest of the logic for the loop
in line 2490 to be skipped, which means no Makefiles are
generated for the tcg target tests.

This commit allows QGA to write to Windows event log using Win32 API's
ReportEvent() [1], much like syslog() under *nix guests.
In order to generate log message definitions we use a very basic message
text file [2], so that every QGA's message gets ID 1. The tools
"windmc" and "windres" respectively are used to generate ".rc" file and
COFF object file, and then the COFF file is linked into qemu-ga.exe.

Running `configure -extra-cflags=-Wunused-parameter` triggers the problem.

When determining the endiandness of the target architecture we're
building for a small program is compiled, which in an obfuscated
way declares two strings. Then, we look which string is in
correct order (using strings binary) and deduct the endiandness.
But using the strings binary is problematic, because it's part of
toolchain (strings is just a symlink to
x86_64-pc-linux-gnu-strings or llvm-strings). And when
(cross-)compiling, it requires users to set the symlink to the
correct toolchain.
Fortunately, we have a better alternative anyways. We can mimic
what compiler.h is already doing: comparing __BYTE_ORDER__
against values for little/big endiandness.
