In case a link is pointing_to an absolute path and we are using $DESTDIR
we fail in case the target is missing.
This is incorrect because we may need to use an absolute path to an
already installed file that is in $DESTDIR.
So if an absolute target is not existing, check if we have such file in
$DESTDIR before failing for real.
This has been broken ever since the original implementation. Due to a
typo, the optimization flag used a zero instead of an uppercase "o",
which the compiler then breaks on during argument parsing because it is
an invalid argument.
Fixes#10267
In print_options() k was a string instead of OptionKey, but
self.yielding_options expects OptionKey. Not sure how this has not been
catched by mypy.
Fix by keeping k as OptionKey which makes self.yielding_options useless.

Although Qt6 has decided these are "internal" commands and should never
be run directly, so they don't get symlinked to /usr/bin at all, and are
only available in the qt_dep.bindir anyway.
But, the general naming pattern should be followed on principle.
Qt now has official guidance for the symlinked names of the tools, which
is great.
Qt now officially calls the tools `fooX` instead of `foo-qtX` where the
major version of Qt is X. Which is not great, because a bit of an
unofficial standard had prior art and now needs to change, and we never
adapted.
Prefer the official name whenever looking up qmake, and in the
testsuite, specifically look only for the official name on versions of
qt which we know should have that.
Fixes regression in commit c211fea513. The
original dependency lookup looked for `qmake-{self.name}`, i.e.
`qmake-qt5`, but when porting to config-tool, it got switched to
`qmake-{self.qtname}` i.e. `qmake-Qt6`, which was bogus and never
worked. As a result, if `qmake-qt5` and `qmake` both existed, and the
latter was NOT qt5, it would only try the less preferred name, and then
fail.
We need to define self.name early enough to define the configtool names,
which means we need to set it before running the configtool __init__()
even though configtool/pkgconfig would also set it to the same value.
Mark the tests as passing on two distros that were failing to detect
qmake due to this issue, and were marked for skipping because we assumed
that the CI skipping there was an expected case rather than an old
regression.
Qt 6.1 moved the location of some binaries from QT_HOST_BINS to
QT_HOST_LIBEXECS as noted in the changelog:
c515ee178f Move build tools to libexec instead of the bin dir
- Tools that are called by the build system and are unlikely to be
called by the user are now installed to the libexec directory.
https://code.qt.io/cgit/qt/qtreleasenotes.git/tree/qt/6.1.0/release-note.txt
It's possible to help the 'qt' module find the tools by adding Qt's
libexec directory to the PATH environment variable, but this manual
workaround is not ideal.
To compensate, meson now needs to look for moc, rcc, uic, etc. in
QT_HOST_LIBEXECS as well as QT_HOST_BINS.

argparse is the gift that keeps on giving, hahaha. Suppress the script
argument when --version is specified to avoid "required argument not
provided" errors, and print the python version.
The version argument is required in order to make this baseline
functional as a resolved python for find_program, which may specify a
version and expect this to work with python itself. Our incomplete CLI
wrapper over the python CLI interface was missing this.
Fixes#10162
Commit a0cade8f introduced a typo and wrongly check for
gtk4-update-icon-cache twice.
If gtk4-update-icon-cache (gtk4) is not found, look for
gtk-update-icon-cache (gtk3) instead.
We print a warning if a compilation database isn't successfully
generated, which is good, because that gives some visibility in case the
user really wanted to use the compdb. But warnings default to being
fatal with --fatal-meson-warnings, which is not so good, because this
isn't a very important warning at all, and we'd rather not error out in
such cases when building works fine and a random bonus IDE feature
doesn't work.
Mark this particular warning as non-fatal.
Fixes side issue in https://github.com/mesonbuild/wrapdb/pull/343#issuecomment-1074545609
While gtk+-3.0 / gtk4 do exist, they have never provided the location of
the gtk-update-icon-cache program as a pkgconfig variable. Trying to
find one anyway, resulted in two things happening:
- a useless dep lookup
- a fatal-meson-warnings error and build failure because the
get_pkgconfig_variable() in question never existed
The desktop-file-utils package is a package solely providing some
command line programs, and has never provided a pkg-config file in the
first place, so this always logged that the dependency was not found and
fell back to normal find_program_impl(), although without
fatal-meson-warnings build errors.
Fixes#10139
The code in the C++ and Fortran compilers' language_stdlib_only_link_flags
method is broken and cannot possibly have ever worked. Instead of
splitting by line, it splits by whitespace and therefore, instead of
the last line of the compiler output:
programs: =/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
libraries: =/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/12.0.0
it is only the last field that has its first 11 characters removed.
Instead of reinventing the wheel with a new and brittle pattern,
reuse get_compiler_dirs.

Verbose, non-parallel tests generally print their output as they run, rather than
after they finish. This however is not the case if stdout of the test is parsed
as is the case for TAP and Rust tests. In this case, the output during the run
is the list of the subtests, but stderr still has to be printed after the test
finishes.

Unfortunately, checking for strings without context is exceedingly prone
to false positives, while missing anything that indirectly opens a file.
Python 3.10 has a feature to warn about this though -- and it uses a
runtime check which runs at the same time that the code fails to open
files in the broken Windows locale. Set this up automatically when
running the testsuite.
Sadly, Python's builtin feature to change the warning level, e.g. by
setting EncodingWarning to error at startup, is utterly broken if you
want to limit it to only certain modules. This is tracked in order to be
more efficiently ignored at https://bugs.python.org/issue34624 and
https://github.com/python/cpython/pull/9358
It is also very trigger happy and passing stuff around via environment
variable either messes with the testsuite, or with thirdparty programs
which are implemented in python *such as lots of gnome*, or perhaps
both.
Instead, add runtime code to meson itself, to add a hidden "feature".
In the application source code, running the 'warnings' module, you can
actually get the expected behavior that $PYTHONWARNINGS doesn't have. So
check for a magic testsuite variable every time meson starts up, and if
it does, then go ahead and initialize a warnings filter that makes
EncodingWarning fatal, but *only* when triggered via Meson and not
arbitrary subprocess scripts.
We didn't consider that it has arguments following it, so the resulting
compiler command line ended up with stuff like:
-L=-rpath-link -L=-L=/path/to/directory -L=more-args
and the directory for rpath-link got eaten up as a regular -L path to
the compiler rather than being passed as -Xlinker to the linker.
Then the -rpath-link would consume the next -Xlinker argument, end up
with the wrong rpath-link (may or may not cause link errors) and then
disappear arguments we need.
As an example failure mode, if the next argument is -soname this treats
the soname text as an input file, which probably does not exist if it
was generated in a subdirectory, and also because it can never be
successfully built in the first place -- though if it did, it would link
to itself which is very wrong.
If --no-rebuild is used, the test program might not exist, spawning a
FileNotFoundError inside a long traceback rooted in subprocess.Popen
trying to run that test program. Current versions of Meson even say it's
an "unhandled python exception".
But we can do one better and actually tell the user what is wrong, why,
and what to do to fix it. And we can do so before getting waist deep in
partially running tests.
Fixes#10006
This header is required anyway. And the compile test for linking to libc
with the gettext symbol, can succeed when we try to use the literal
symbol name without includes, but fail later during project build,
because actually including libintl.h might redefine the function to match
a forked symbol. This happens when GNU libintl is installed as a
standalone library on systems that have a less fully-featured gettext
implementation.
So, by including the header in has_function, we can ensure that we test
against the default resolved header. In the event that the symbol which
is #define'd by the header is 'libintl_gettext', linking will fail against
libc even when a builtin gettext does exist, and we will fall back to the
intl dependency that provides -lintl (and which is needed to properly
use the default header).
Of course, even that probably won't work.
has_function(prefix: '...') is useless to check the difference between
builtins and external library functions. It has code to detect
"builtins" that misfires in some cases (previously seen with iconv_open).
Instead compile an open-coded test file that this intl dependency
implementation fully controls, that doesn't get up to imaginative edge
cases like trying to find `__builtin_gettext`.
It's the only way to be sure.
Fixes compiling against the intl dependency on e.g. Alpine Linux when the
libintl package is installed.
Android requires shared modules that use symbols from other shared
modules to be linked before they can be dlopen()ed in the correct
order. Not doing so leads to a missing symbol error:
https://github.com/android/ndk/issues/201
We need to always allow linking for this. Also add a soname, although
it's not confirmed that it's needed, and it doesn't really hurt if it
isn't needed.
On Windows using MSYS2 MinGW installing the package `mingw-w64-x86_64-wxmsw3.1` provides `wx-config-3.1`. I have tried building my software by making this exact change and it build correctly.
In commit b30dddd4e5, various refactorings
were done, during which a kwarg got accidentally dropped from the
function that determined part of the log message. As a result, a ':'
suddenly appeared in the log message where none should be.

Checking if "-Werror=shadow with local shadowing" compiles: YES
What actually happened:
Checking if "-Werror=shadow with local shadowing" : compiles: YES

RuntimeError is way too generic when we have an explicit class for
"Meson reports to the user, something went wrong".
Moreover we now tell people that generic exceptions are "Meson bugs and
should be reported", so our failure to do the technically correct thing
and report the right kind of exception means we get haunted by demons of
confusion. Specifically, people complain to us that Meson told them
"there is a bug in Meson" when their install fails due to meson.build or
build environment issues.
This has never worked for built/found programs, only for script files.
In commit 2fabd4c7dc scripts learned an
attribute stating which subproject they came from. In commit
3990754bf5 dist scripts learned to run
even from a subproject, and relied on that attribute to know when, in
fact, they came from a subproject.
Unfortunately the original attribute was only set in one half of an
if/else, and the other half returned early with only part of the work
done.
Fixes#9964
In commit 0deab2ee9e we added the ability
to pass a declare_dependency() to any compiler method that accepts
"dependencies", but we never marked the version it is available since.
Fixes#9957
For static library crates that depend on other internal static library
crates, all link_with targets get promoted to link_whole targets. Due to
a bug, only link_with targets are considered when generating a Rust
target for the ninja backend. This made it impossible to link a Rust
static library with another internal Rust static library.
This change fixes that issue by chaining link_whole_targets with
link_targets, just like many other languages within the ninja backend.
Basically the last thing we did during target processing was to generate
shlib symlinks for e.g. libfoo.so -> libfoo.so.1.
In some cases we would dispatch to another function and return early,
though, which meant we never got far enough to generate the symlinks.
This then led to breakage when people tried to compile against libfoo.so
This surely breaks -uninstalled.pc usage, and also caused problems in
https://github.com/rust-lang/rust/pull/90260
For example:
```
meson builddir \
--native-file vs2019-paths.txt \
--native-file vs2019-win-x64.txt \
--cross-file vs2019-paths.txt \
--cross-file vs2019-win-arm64.txt
```
This was causing the error:
> ERROR: Multiple producers for Ninja target "/path/to/vs2019-paths.txt". Please rename your targets.
Fix it by using a set() when generating the list of regen files, and
add a test for it too.
