Do you mean a dummy replacement for x86_64-apple-darwin13-pkg-config
(i.e., the symlink that's installed if you build pkg-config without the --disable-host-tool
flag; or a replacement for pkg-config itself?
from osxcross.
well, I suppose that setting PKG_CONFIG_LIBDIR
is enough to make any pkg-config unaware of host libraries and make it work with the osxcross sysroot, or not?

I just checked with all the other pkg-configs I have (host, mingw32/64), and they all have a single hardcoded path, and I can change that only with PKG_CONFIG_LIBDIR
. So that's the only "identity" of a pkg-config, and that is what osxcross should set imo.

You can use PKG_CONFIG_PATH
, which will accept a colon-delimited arbitrary list.
from osxcross.
No, because there might be other user scripts that set PKG_CONFIG_PATH
. That is what the flag is for. The toolchain base path should go in PKG_CONFIG_LIBDIR, and that too takes a colon delimited list (and it does in my three different toolchains, with "$SYSROOT/lib/pkgconfig:$SYSROOT/share/pkgconfig"
).

Interesting! I'll have to play around with that some more — the docs aren't super clear on that at all, but it seems you're quite right.
I see now there is also PKG_CONFIG_SYSROOT_DIR
, but it doesn't seem to work all that well in combination with PKG_CONFIG_PATH
/PKG_CONFIG_LIBDIR
...
Also (not sure what your use case is) keep in mind that pkg-config isn't used near much on Darwin (not nearly as much as it should be, IMO), due two-level namespace in dynamic linkage. But since you mentioned macports, you might also want to check out how brew
handles pkg-config paths/files (and dependencies in general).
from osxcross.
I think that PKG_CONFIG_SYSROOT_DIR
is not the right way, because it will nevertheless look int the host pkgconfig directories and then mangle the paths. I don't think this is really what to be expected (as the message in the mailing list of your link points out).
My use case is having a unified build system for a project of mine that works on native osx, mingw and linux and cross compilation environments where possible, and I'm doing that in a linux-ish way (all libs have a configure script which possibly queries pkg-config).
I just skimmed over it (I'm familiar with ruby, brew and OSX in general), but brew seems to set PKG_CONFIG_LIBDIR
too.

Done with a8fdaa3, but a little bit different:
*-apple-darwinXX-pkg-config
always returns 1
as exit code unless OSXCROSS_PKG_*
is set (which is remapped to PKG_*
).
