• Status: RESOLVED OBSOLETE

The build.log is pretty short:

Since i want to build the x86 variant on amd64 with multilib-portage, it already uses the right libdir (/usr/lib32 in this case), but would also need to support CXXFLAGS to get the additional -m32 argument. Since that is missing, it tries to build a 64bit object with 32bit libs, which obviously fails.

Created attachment 494758 [details, diff]
update qt install test to respect *FLAGS

This fixed the problem for me.

PyQt4 is gone.
