PkgConfig automatically removes -L paths from libdirs if the -L points
to a system path. It knows what these paths are by taking this as a
configure option at build time, which the distro maintainers set
appropriately and everything works. This allows one to have two
versions of a package installed, a system and non system, and then
override PKG_CONFIG_PATH to use the non system version, and everything
just works. For non-pkgconfig dependencies (such as LLVM) meson needs to
strip these themselves to avoid breaking the above use case.
Without specifying a custom install directory string, get_custom_install_dir() returns True. So for the `Libs` entry I was getting this:
Libs: -L${prefix}/True -lfoo
Now it behaves as expected:
Libs: -L${libdir} -lfoo
subproject using wrap-file is broken since commit (68bd64c Prevent
projects from directly grabbing files from other subprojects. )
subproject with wrap-file usually have version number after name
- **sproj_name** is `zlib-1.2.8` according to `directory = zlib-1.2.8`
of zlib.wrap
- but **self.subproject** `zlib`
I've typo'd "value" for the last time, options needs a kwargs validator.
This validator is slightly different than the one used by the main
parser, since it operates on a much simpler representation than the
other one does, and they are not interchangeable.
This also changes the optinterpreter to use pop on 'type' and
'description' so that they're not passed to the validator as kwargs.
The new implementation will correctly pick boost from 3 possible
locations on windows and two locations on posix compatible OSs.
The new search algorithm also differentiates between debug and
release builds of Boost and multi or single threading builds.
It was also decided to map "Meson modules" to Boost software libraries
and not Boost modules since it there are a lot of options regarding
linking. Some modules can even be used either as headers-only or with
dynamic linking.
This commit also fixes a bug that prevented header-only use on Windows.
Fixes: #2274#2239#1803#669
/WHOLEARCHIVE must go to AdditionalOptions, not AdditionalDependencies
and we must add a project reference to trick msbuild/visual studio into
building a target that is built from only libraries linked in via
/WHOLEARCHIVE.
This allows a CustomTarget to be indexed, and the resulting indexed
value (a CustomTargetIndex type), to be used as a source in other
targets. This will confer a dependency on the original target, but only
inserts the source file returning by index the original target's
outputs. This can allow a CustomTarget that creates both a header and a
code file to have it's outputs split, for example.
Fixes#1470
