This replaces calls to .rstrip('git'), .rstrip('svn') with a regex that
takes the leading numbers and dots, and throws away the rest. This also
moves the code up to the ConfigToolDepdency level, since these config
tools are of various quality and some of them are good, and some are
not. This shouldn't affect well behaved tools.
This should future proof LLVM against future suffixes (like someone
doing something strange like using Mercurial as a VCS).
I'm not sure this is a good idea, but at the moment it seems a bit too easy
to write something like dep.get_pkgconfig_variable('inculdedir:') (sic) and
not notice it's not doing anything useful.
Because FreeBSD's llvm-config adds -l/usr/lib/libexecinfo.so when asked
for system-libs, which is bogus. We'll remove the leading -l from any
argument that also ends with .so.
Special case ThreadDependency by taking compiler's flags and
PkgConfigDependency by adding them in requires(.private) instead. For
other Dependency objects just take their link_args and compile_args.
Closes#2725
If LLVM is built from a git mirror instead of from SVN it will have
"git-<very short sha>" at the end of the version. We need to remove that
so that version comparison will work correctly.
Fixes: #2786
Using NotImplementedError throws an ugly traceback to the user which
does not print the line number and other information making it
impossible to figure out what's causing it.
Also override it for internal dependencies because self.name is "null"
for them.
The sysconfig config variables are different on MSYS2 and the paths
are also different. We now also use the full path to the import or
static library instead of using -Lfoo -lpython35 etc.
Also obey the value of the 'static' keyword argument.
sysconfig.get_platform() returns 'mingw' with MSYS2, so we need to
use some other method; in this case I chose to use the CC that
Python was compiled with, which is a relatively reliably indicator
unless people start using Python on Windows compiled with Clang or
something.
/usr/bin/env does not exist on Haiku since there's no /usr. The actual
location is /bin/env. Detect that case and directly use the
interpreter being passed to `env` in the shebang.
Also reorganize the Windows special cases which does the same thing.
The MinGW toolchain can read MinGW paths, but Python cannot and we
sometimes need to parse the libs and cflags manually (for static-only
library searching, for instance). The MinGW toolchain can always read
Windows paths with `/` as path separater, so just use that.
Also try harder to find a compiler that dependencies can use.
This means that in C++-only projects we will use the C++ compiler for
compiler checks, which can be important.
MSVC cannot handle MinGW-esque /c/foo paths, convert them to C:/foo.
We cannot resolve other paths starting with / like /home/foo so leave
them as-is so the user gets an error/warning from the compiler/linker.
These paths are commonly found in pkg-config files generated using
Autotools inside MinGW/MSYS and MinGW/MSYS2 environments.
Currently this is only done for PkgConfigDependency.
While finding an external program, we should only split the shebang
once since that is what Linux and BSD also do. This is also why
everyone uses #!/usr/bin/env in their shebangs since that allows
you to run an interpreter in a path with spaces in it.
See `man execve` for more details, specifically the sections for
interpreter scripts.
