Because of how files and executables work on Windows, scripts that use
an interpreter must have an extension, and that extension must be
associated with an interpreter. The full list of executable extensions
is available in the PATHEXT environment variable.
However, UNIX-like OSes use an executable bit and read the shebang to
figure out what interpreter to use, and the scripts don't need to have
extensions. We can now detect these scripts using find_program by
manually searching in PATH and reading the shebang.
Target-specific compiler options should be split into pre-processor
defines, include directories, and additional options, then
escaped/quoted and added to the appropriate portions of the project
file.
The "115 spaces backslash" test now checks that backslashes and spaces
now work properly in all three places.
At the same time, this also adds a bunch of tests that document and keep
track of how we expect quoting to pass through via Ninja to the
compiler.
We need at least Ninja 1.6.0 for this.
This fixes https://github.com/mesonbuild/meson/issues/489
After c01b183e5, the mtime of coredata.dat is always newer than all the
other build files, which made regen_checker think that they always had
to be regenerated. Now we set the mtime of the file to a value before
the build files are generated and that makes everything behave as it did
earlier.
This gives a clearer output when the dependency is not required or has a
fallback subproject otherwise the user is left wondering why the optional
dependency wasn't used or why the fallback subproject is being used.
Just exit immediately when there's no pkg-config file found instead of putting
everything else in a huge 'else:'. Much clearer and avoids one level of
indentation.
No code changes accompany this.
Trivially correct typo fix. Didn't actually break anything because the
fallback is libdir anyway, and we always install static libraries to
libdir.
Pointed out by Zhe Wang (0x1997).
The Meson script is not always in $scriptdir/../../ -- for instance if
installed with pip on Windows, the scriptdir is in:
C:/Python35/Lib/site-packages/meson-0.33.0.dev1-py3.5.egg/mesonbuild/scripts
and the meson.py script is in:
C:/Python35/Scripts
So, let's save the path available as Environment().meson_script_file
into the coredata.dat private file and use that to invoke Meson when
doing regen.
Also, let's fetch the backend that was used from the coredata too
instead of hard-coding vs2010.
Both these were causing a hard failure while doing regen with msbuild or
visual studio.
Otherwise we'll mark the build directory as successfully configured even
if there's an error while doing the actual generation.
