Meson itself *almost* only cares about the build and host platforms. The
exception is it takes a `target_machine` in the cross file and exposes
it to the user; but it doesn't do anything else with it. It's therefore
overkill to put target in `PerMachine` and `MachineChoice`. Instead, we
make a `PerThreeMachine` only for the machine infos.
Additionally fix a few other things that were bugging me in the process:
- Get rid of `MachineInfos` class. Since `envconfig.py` was created, it
has no methods that couldn't just got on `PerMachine`
- Make `default_missing` and `miss_defaulting` work functionally. That
means we can just locally bind rather than bind as class vars the
"unfrozen" configuration. This helps prevent bugs where one forgets
to freeze a configuration.
Mypy know what to do with these and isn't confused, but some versions of
python 3.5 (at least 3.5.2) can't handle these annotations. By making
them strings the python interpreter wont try to evaluate them.
Fixes#5326
Some things, like `method[...](...)` or `x: ... = ...` python 3.5
doesn't support, so I made a comment instead with the intention that it
can someday be made into a real annotation.
Instead of using the ___cmp__ method just straight up compare the two
values, since we've already converted numbers to ints and split
non-numeric seperators this is sufficient, and 4x faster
This patch creates an enum for selecting libtype as static, shared,
prefer-static, or prefer-shared. This also renames 'static-shared'
with 'prefer_static' and 'shared-static' with 'prefer_shared'. This is
just a refactor with no behavioral changes or user facing changes.
Fix get_library_dirs() on FreeBSD to only return /usr/local/lib,
/usr/lib and /lib as the default location to look for libraries.
FreeBSD does not use lib/${platform} or lib64 by default. In general,
those directories should not exist, but in case they do, ensure they're
not picked up.
Fix defaul_libdir() on FreeBSD. The current behaviour of using
usr/lib64 if that exists is wrong on FreeBSD. The default should be to
always use usr/lib, even if usr/lib64 exists as a folder in the file
system. Fix this by checking if we're running on FreeBSD and then
always return 'lib' in default_libdir().
Mypy struggles with the imperative form of Enum declaration, and
upstream doesn't consider it a bug, they recomend using the class form
for enums that are going to be externally exposed.
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.
