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).

I haven't seen a message confirming if the suggested solution worked, but I am experiencing a similar problem---failure to link GHC due to relocation truncation errors---on a different environment (Ubuntu, PowerPC 32 bit). I have tried the above workaround, but it did not solve my problem. Furthermore, based on this (http://osdir.com/ml/bug-binutils-gnu/2009-08/msg00068.html) binutils thread (sorry, there is probably a better source to reference), it appears this problem was not fixed until very recently. Any additional information or suggested workarounds would be much appreciated. {c}
