So I tried doing an unregisterised ppc build with:

echo "GhcUnregisterised=YES" >> mk/build.mk echo "GhcWithNativeCodeGen=NO" >> mk/build.mk echo "SplitObjs=NO" >> mk/build.mk

Are these the right build config settings?

Yes.

but this failed with: : Linking dist-stage2/build/ghc/ghc ... : (.text+0x20): relocation truncated to fit: R_PPC_REL24 against symbol `__libc_start_main@@GLIBC_2.0' defined in .glink section in /usr/lib/gcc/ppc64-redhat-linux/4.4.0/../../../../lib/crt1.o /usr/lib/gcc/ppc64-redhat-linux/4.4.0/crtbegin.o:(.fini+0x0): relocation truncated to fit: R_PPC_REL24 against `.text'

Does using -mlongcall help? e.g.: SRC_CC_OPTS += -mlongcall SRC_HC_OPTS += -optc-mlongcall (you can probably get away with something rather more specific, but hopefully this will work). Thanks Ian
