This seems to be related to deleting the current working directory.
Simply deleting all of the trees inside the build directory instead
seems to fix it. This only appears with some combination of generated
targets, running the test case against say "1 trivial" doesn't show the
bug.
See this mesa bug: https://bugs.freedesktop.org/show_bug.cgi?id=109071
Since `_process_libs` appends the lib's dependencies this list already,
the final return value of `_process_libs` will end up after its
dependencies, which is the wrong way around. (The lib must come first,
then its dependencies)
The easiest solution is to simply pre-pend the return value of
`_process_libs` rather than appending it, so that its dependencies come
after the library itself.
Closes#4091.
llvm-config --libfiles --link-shared wants to link to a bunch of shared
libraries which don't exist, so we end up at dev.py:308, but the guess
that makes ('libLLVM*.dll') doesn't take into account the existence of
implibs (which is fixable), but even if it did 'libLLVM-7.0.dll.a'
doesn't seem to exist... so not sure how to fix this...)
Also some steps towards making that work:
Adjust helper_create_binary_wrapper for MSYS2. The .bat wrapper should
run msys2 python, not try to invoke the 'py' python launcher (which may
not be present)
Suppress echoing of the command in helper_create_binary_wrapper
(otherwise the echoed command can interfere in interpreting the output
of the wrapped command, which seems to be the case when it's
llvm-config)
This variant was added to allow introspection before configuring a build
directory. This is useful for IDE integration to allow displaying and/or
setting options for the initial configuration of the build directory.
It also allows showing basic information about the project even if it's
not yet configured or configuring failed.
The project 'name' field in --projectinfo is used inconsistently:
For the top level project it always shows the name configured in
the top level meson.build file. For subprojects it's referring to the
name of the directory the subproject's meson.build is contained in.
To have a consistent output and preserve the existing behavior this adds
the 'descriptive_name' field which always shows the name set in the
project.
To be consistent the 'descriptive_name' field was also added to the
--projectfiles variant that uses an already configured build.
It also extends the information shown with the list of buildsystem-files.
This is currently only implemented in the variant for unconfigured
projects.
Fixed-size hash makes paths shorter and prevents doubling of path length
because of subdir usage in target id: "subdir/id" would generate
"subdir/{subdir-without-slashes}@@id" target otherwise.
Export construct_id_from_path() to aid tests.
Add a separate unit test for this function to make sure it is not broken unexpectedly.
Closes#4226.
this adds support for generating pkgconfig files for c#.
The difference to c and cpp is that the -I flag is not known to the c#
compiler, but rather the -r flag which is used to link a .dll file into
the compiled library.
However this opens the question of validating which pkgconfig files can
be generated (depending on the language).
This implements 4409.
part of using ICC is configuring LD_LIBRARY_PATH so that you can link
with several Intel specific .so's. Currently meson blanket overrides the
LD_LIBRARARY_PATH in several tests which breaks them. Instead prepend
the test dir td LD_LIBRARY_PATH. Fixes 6 tests with ICC.
This commit adds a nice decorator helper for skipping tests when they
require the compiler to implement a specific base option, and uses it to
turn off b_sanitize tests, which fixes some tests on ICC.
samu prints a different message when the build is a no-op, so make
assertBuildIsNoop consider that as well.
Also, if compile_commands.json cannot be found, just skip the test. This
seems reasonable since meson just produces a warning if `ninja -t compdb`
fails.
Finally, only capture stdout in run_meson_command_tests.py, since the
backend may print messages the tests don't recognize to stderr.
Fixes#3405.
When trying to cross-compile mesa on an aarch64 system, I noticed some
strange behavior. Meson would only ever find the wayland-scanner binary
in my host machine's sysroot (/mnt/amethyst):
Native dependency wayland-scanner found: YES 1.16.0
Program /mnt/amethyst/usr/bin/wayland-scanner found: YES (/mnt/amethyst/usr/bin/wayland-scanner)
It should be finding /usr/bin/wayland-scanner instead, since the
wayland-scanner dependency is created as native. On closer inspection,
it turned out that meson was ignoring the native argument passed to
dependency(), and wuld always use the pkgconfig binary specified in my
toolchain instead of the native one (/usr/bin/pkg-config):
Native dependency wayland-scanner found: YES 1.16.0
Called `/home/lyudess/Projects/panfrost/scripts/amethyst-pkg-config
--variable=wayland_scanner wayland-scanner` -> 0
Turns out that if we create a dependency() object with native:false, we
end up caching the pkg-config path for the host machine in
PkgConfigDependency.class_pkgbin, instead of the build machine's
pkg-config path. This results causing in all pkg-config invocations for
dependency() objects to use the host machine's pkg-config binary,
regardless of whether or not 'native: true' was specified when the
dependency() object was instantiated.
So, fix this by never setting PkgConfigDependency.class_pkgbin for cross
dependency() objects. Also, add some test cases for this. Since
triggering this bug can be avoided by creating a dependency() objects
with native:true before creating any with native:false, we make sure
that our test has two modes: one where it starts with a native
dependency first, and another where it starts with a cross dependency
first.
As a final note here: We currently skip this test on windows, because
windows doesn't support directly executing python scripts as
executables: something that we need in order to point pkgconfig to a
wrapper script that sets the PKG_CONFIG_LIBDIR env appropriately before
calling pkg-config.

AR wasn't reset in the environment, so this test could fail if more than one
language compiler was specified in the environment and the linker wasn't
'ar'
Handle clang's cl or clang-cl being in PATH, or set in CC/CXX
Future work: checking the name of the executable here seems like a bad idea.
These compilers will fail to be detected if they are renamed.
v2:
Update compiler.get_argument_type() test
Fix comparisons of id inside CCompiler, backends and elsewhere
v3:
ClangClCPPCompiler should be a subclass of ClangClCCompier, as well
Future work: mocking in test_find_library_patterns() is effected, as we
now test for a subclass, rather than self.id in CCompiler.get_library_naming()
