Bug 576146 – dev-libs/wayland: Proper wayland-scanner build/install handling for multilib

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Mart Raudsepp 2016-03-01 18:01:39 UTC]

While working on bug 575212, it turned out our multilib wayland-scanner handling is suboptimal. It gets built for 32bit, but not installed. But a pkgconfig file for 32bit is installed, which points at the 64bit /usr/bin version.
Need to look into it in more detail to see if we actually want both versions, or help upstream support a clean way to disable it (--with-host-scanner isn't quite right for this case as it might be a first install and there is no host scanner), and maybe it is needed internally then still to generate some headers or marshalling code.
The key is probably to see how other packages needing wayland-scanner would be working (i.e wayland-protocols/weston/etc), and to not forget cross-compilation use cases in addition to multilib.

Upstream is appreciating help figuring all this out as well.


As bug 575212 was fixed, opened this one to not forget about this lingering smaller issue.

I think that might explain this compile error I see on a binhost:

[..]
./wayland-scanner: error while loading shared libraries: libexpat.so.1: cannot open shared object file: No such file or directory
make: *** [Makefile:3020: protocol/wayland-server-protocol.h] Error 127
make: *** Waiting for unfinished jobs....
./wayland-scanner: error while loading shared libraries: libexpat.so.1: cannot open shared object file: No such file or directory
make: *** [Makefile:3017: protocol/wayland-protocol.c] Error 127
./wayland-scanner: error while loading shared libraries: libexpat.so.1: cannot open shared object file: No such file or directory
make: *** [Makefile:3023: protocol/wayland-client-protocol.h] Error 127
[..]

Would be great to see fixed.  Thanks in advance!
