Hi ports --
I have successfully built QT4 on Loongson, patches below. However, it
segfaults whenever I try to launch any QT4 program. Nothing useful comes
from the backtraces.
I tried to build QT4 with -O0 but the build crashes when trying to link
libwebcore.a (Could not read symbols: Memory exhausted). Does anyone know
how I'd go about building everything with -O0, which seems to work OK, but
build QTWebKit at the default of -O2 so I don't get the memory exhaustion
errors?
The patches may be somewhat hacky, but they work.
Thanks.
~Brian
