We did a big session fighting through this, and when I built with `cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo` using the upstream files, everything magically started working. So we tossed in export DEB_CFLAGS_MAINT_APPEND = -O2 export DEB_CXXFLAGS_MAINT_APPEND = -O2 to the ppc lines, and it all worked. I'm going to now try with a PPA build and test moving ppc back to -O2, and then go the other way and try amd64 w/ O3 and see what happens. -- ----------------------- Dr. John Chittum Engineering Manager, Canonical, Debcrafters
