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
A custom_target, if install is set to true, will always be built by
default even if build_by_default is explicitly set to false.
Ensure that this does not happen if it's set explicitly. To keep
backward compatibility, if build_by_default is not set explicitly and
install is true, set build_by_default to true.
Fixes#4107
Since trying to cross compile for Windows from Linux (WSL) and having
paths like this:
'-L/mnt/c/Program Files (x86)/Microsoft Visual Studio/2017/\
Community/VC/Tools/MSVC/14.15.26726/lib/x64'
I found that the spaces and brackets in the paths weren't properly
escaped by the Ninja backend.
Building a cross compiler (`build == host != target`) is not cross
compiling. As such, it doesn't make sense to handle it under
`is_cross_build`.
(N.B. Building a standard library for a cross compiler would require
cross compiling, but Meson has support to do such a thing as part of a
compiler build currently.)
If you change only some project in meson.build,
only that .vcxproj file will be updated and reloaded.
If you change something not related to VS solution and projects
or simply touch the meson.build file, nothing will be reloaded.
Accomodate clang-cl /showIncludes output in detect_vs_dep_prefix().
clang-cl outputs lines terminated with \n, not \r\n
v2:
should invoke the detected compiler, not hardcode 'cl'
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()
This reduces the build time about 2 sec. The result itself is not hard
to calculate. However, persistent join calls with the same 2 strings are
not that usefull. This also caused about 600'000 calls to
get_target_dir, we are now down to 60'000 calls form this function to
get_target_dir.
Remove the code responsible for implicitly compressing manpages as .gz
files. It has been established that manpage compression is a distro
packager's task, with existing distros already having their own
implementations of compression.
