macOS provides the tool `lipo` to check the archs supported by an
object (executable, static library, dylib, etc). This is especially
useful for fat archives, but it also helps with thin archives.
Without this, the linker will fail to link to the library we mistakenly
'found' like so:
ld: warning: ignoring file /path/to/libfoo.a, missing required architecture armv7 in file /path/to/libfoo.a
Instead of only doing a naive filesystem search, also run the linker
so that it can tell us whether the -F path specified actually contains
the framework we're looking for.
Unfortunately, `extraframework` searching is still not 100% correct in
the case when since we want to search in either /Library/Frameworks or
in /System/Library/Frameworks but not in both. The -Z flag disables
searching in those prefixes and would in theory allow this, but then
you cannot force the linker to look in those by manually adding -F
args, so that doesn't work.
In some cases (see #4817) it's helpful if the output file uses the
same newlines as the input file without translating them to the
platform defaults.
open() by default recognizes all newline styles and translates them
to "\n" and then to the platform default when writing.
Passing "" to "newline" disables the translation and lets us pass through
the original newline characters.
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
If builddir and sourcedir have different drive letters, a relative path
doesn't exist, and os.path.relpath fails with a ValueError exception.
This just fixes the places which are hit by test cases in a simple-minded
way. There are several other uses of os.path.relpath(), which might be
suspect.
It's much better to directly query the machine in question rather than
do some roundabout "is_cross" thing. This is the first step for much
natve- and cross- code path deduplication.
The use of ABC classes (like MutableSet) is deprecated currently, in
python 3.8 the aliases in collections will be dropped and only the ones
in collections.abc will remain. collections.abc has existed since python
3.3, so there is no backwards compatibility risk.
Correct version_compare_condition_with_min() for the case where no minimum
version is established by the version constraint. Add a simple test.
Also fix test_feature_check_usage_subprojects by escaping regex
metacharacters.
if |condition| is '<', '<=' or '!=', the minimum version satisfying the
condition is 0, so the minimum version for a feature is never met.
if |condition| is '>=' or '==', the minimum version satisfying the condition
is the version compared with, so the minimum version for a feature must be
less than or equal to that.
if |condition| is '>', the minimum version satisfying the condition is
greater than the version compared with, so the minimum version for a feature
must be less than that
(it's this last condition that makes this function necessary, as in all
other cases we could establish a definite minimum version which we could
compare to see if it's less than or equal to the current version)
Currently this trims '0.48.0.dev1' to '0.48.0', and then requires exactly
that version in the generated meson.build for the test.
Just use the exact version.
Also only use a 'project(meson_version:)' constraint in the generated
project if a version is specified
Also remove unused grab_leading_numbers
Use mesonlib.for_windows or mesonlib.for_cygwin instead of
reimplementing them.
Add CrossBuildInfo.get_host_system to shorten the repeated the code in
the mesonlib.for_<platform> methods.
* get_library_naming: Use templates instead of suffix/prefix pairs
This commit does not change functionality, and merely sets the
groundwork for a more flexibly naming implementation.
* find_library: Fix manual searching on OpenBSD
On OpenBSD, shared libraries are called libfoo.so.X.Y where X is the
major version and Y is the minor version. We were assuming that it's
libfoo.so and not finding shared libraries at all while doing manual
searching, which meant we'd link statically instead.
See: https://www.openbsd.org/faq/ports/specialtopics.html#SharedLibs
Now we use file globbing to do searching, and pick the first one
that's a real file.
Closes https://github.com/mesonbuild/meson/issues/3844
* find_library: Fix priority of library search in OpenBSD
Also add unit tests for the library naming function so that it's
absolutely clear what the priority list of naming is.
Testing is done with mocking on Linux to ensure that local testing
is easy
We already have code to fetch and find binaries specified in a cross
file, so use the same code for exe_wrapper. This allows us to handle
the same corner-cases that were fixed for other cross binaries.
Instead of just printing the message in the exception, if it's
a MesonException, also print the file and the line number. If it's an
unknown exception, print the entire traceback so that we can pin-point
what the Meson bug causing it is.
It's possible that the configuration data object has components added
conditionally, and that sometimes an empty configuration data object
is passed on purpose.
Instead, we do the substitution and also warn if no tokens were found
that could've been substituted.
Closes https://github.com/mesonbuild/meson/issues/3826
We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()
* Use _get_callee_args to unwrap function call arguments, needed for
module functions.
* Move some FeatureNewKwargs from build.py to interpreter.py
* Print a summary for featurenew only if conflicts were found. The
summary now only prints conflicting features.
* Report and store featurenew/featuredeprecated only once
* Fix version comparison: use le/ge and resize arrays to not fail on
'0.47.0>=0.47'
Closes https://github.com/mesonbuild/meson/issues/3660
Input files can be in any file encoding, not just utf-8 or isolatin1. Meson
should not make assumptions here and allow for the user to specify the
encoding to use.
Start the process by traversing the tree and adding the S_IWRITE and
S_IREAD bits to the file's mode (which are also preserved on Windows.)
This fixes windows_proof_rmtree's inability to remove read-only files,
which was uncovered in testing the new `install_mode` feature.
Tested: ./run_tests.py passes on Linux, appveyor CI on Windows passes.
Instead of using fragile guessing to figure out how to invoke meson,
set the value when meson is run. Also rework how we pass of
meson_script_launcher to regenchecker.py -- it wasn't even being used
With this change, we only need to guess the meson path when running
the tests, and in that case:
1. If MESON_EXE is set in the env, we know how to run meson
for project tests.
2. MESON_EXE is not set, which means we run the configure in-process
for project tests and need to guess what meson to run, so either
- meson.py is found next to run_tests.py, or
- meson, meson.py, or meson.exe is in PATH
Otherwise, you can invoke meson in the following ways:
1. meson is installed, and mesonbuild is available in PYTHONPATH:
- meson, meson.py, meson.exe from PATH
- python3 -m mesonbuild.mesonmain
- python3 /path/to/meson.py
- meson is a shell wrapper to meson.real
2. meson is not installed, and is run from git:
- Absolute path to meson.py
- Relative path to meson.py
- Symlink to meson.py
All these are tested in test_meson_commands.py, except meson.exe since
that involves building the meson msi and installing it.
There are cases when it is useful to wrap the main meson executable with
a script that sets up environment variables, passes --cross-file, etc.
For example, in a Yocto SDK, we need to point to the right meson.cross
so that everything "just works", and we need to alter CC, CXX, etc. In
such cases, it can happen that the "meson" found in the path is actually
a wrapper script that invokes the real meson, which may be in another
location (e.g. "meson.real" or similar).
Currently, in such a situation, meson gets confused because it tries to
invoke itself using the "meson" executable (which points to the wrapper
script) instead of the actual meson (which may be called "meson.real" or
similar). In fact, the wrapper script is not necessarily even Python, so
the whole thing fails.
Fix this by using Python imports to directly find mesonmain.py instead
of trying to detect it heuristically. In addition to fixing the wrapper
issue, this should make the detection logic much more robust.
The added format argument for configure_file allows to specify the kind of
file that is treated. It defaults to 'meson', but can also have the 'cmake'
or 'cmake@' value to treat config.h.in files in the cmake format with #cmakedefine
statements.
Starting from 8fc4244187, tests
failed on my system (python 3.6 arch) because
shutil.which('meson.py') returns 'meson.py', not './meson.py'.
Refactor that codepath by using os.path.isabs instead of
"m_dir == '.'", also remove the adjacent comment because
it doesn't make much sense.
