I'd like to try to port GHC to powerpc-unknown-linux. There seems to be only x86 HC files available for GHC 5.00.2. Would those be of any help to me?

No, you need unregisterised HC files, which involved a 2-stage build. I already build them for 5.00.2 and i can upload them somewhere, if you want me to. BUT: I also tried to port GHC to powerpc-linux... currently it barfs here: [...] ===fptools== Finished making `all' in cbits ...

I didn't had the time so far to investigate further on this issue... One of the MacOS X porters (IIRC) mentioned to me, that eventually the .hc files are not REALLY unregisterized, but i can't see any problems with them... Here's mk/build.mk, which I used to produce the .hc files: ----------------------------------------------------------------------------- GhcLibWays = port_opts = -O -keep-hc-files-too -optc-DNO_REGS -optc-DUSE_MINIINTERPRETER -fno-asm-mangling -funregisterised -fvia-C GhcLibHcOpts = $(port_opts) # GhcHcOpts = $(port_opts) GhcRtsHcOpts = $(port_opts) EXTRA_CC_OPTS = -DNO_REGS # GhcUnregisterised = YES GhcWithNativeCodeGen = NO StripLibraries = NO SplitObjs = NO ----------------------------------------------------------------------------- I used the same for the second stage, but added: WithGhcHc = $(FPTOOLS_TOP_ABS)/../stage1/obj/bin/ghc and also added the according `--with-hc' option to configure Those I took to the powerpc, unpacked them onto a fresh source tree, and started building... with the above results...
