Created attachment 382050 [details] emerge --info This is regression from crossdev 20140118 and earlier, introduced in 20140729. Most libraries install their .pc files under libdir/pkgconfig; however, crossdev is now finding this using gcc to search for libc.so which does not exist on (at least) MinGW targets, thus all attempts to build software needing these libraries for the targets fail.
Right. The bug comes from the script i686-pc-mingw32-pkg-config. The variable ${libdir} does not return "lib" but the current folder. I can't provide a patch (it's out of my competencies) but the regression is there.
