You can use make -k to keep going, I seem to remember, or use -pgmltrue,

Those tricks got me farther. Now I'm on the target and stuck at:

It could be that gmp is a bit too old for your platform. This has been the case on other rarer platforms, and on (all?) 64bit archs. One solution is to install a native, newer libgmp yourself (from the vendor), and then add appropriate flags to have ./configure and gcc/ghc find the library (if it isn't in a standard location). On Irix I needed: export LDFLAGS="-L/usr/freeware/lib64" export CPPFLAGS="-I/usr/freeware/include" cat >> mk/build.mk <

Turns out that both ghc and gmp are confused about the true nature of the platform. It is AIX on PowerPC64, running in 32-bit mode. After significant tweaking to Makefiles (to add -mpowerpc all over the place), things seem to work. I hope I'll actually have it built later today. Sigh.

This sounds like a similar issue I had on mips64-irix. It wants to run in 32bit mode, but I have to add compiler flags all over the place to get all the tools to use 64 bits. You may need to use similar settings. Most of the flags can be set in mk/build.mk: # C compiler flags SRC_CC_OPTS+=-mabi=64 # Haskell compiler flags, for gcc, and ld SRC_HC_OPTS+=-optc-mabi=64 -opta-mabi=64 -optl-mabi=64 SRC_CC_OPTS+=-L/usr/freeware/lib64 SRC_HC_OPTS+=-L/usr/freeware/lib64 And the following env vars were needed to be set to help out configure: export LDFLAGS="-L/usr/freeware/lib64 -mabi=64" export CPPFLAGS="-I/usr/freeware/include" export CFLAGS=-mabi=64 # make sure we use 64bit linker export LD="/usr/bin/ld -64" And once this is all built, I need to set some flags in ghc/rts/package.conf, in order to have the correct flags passed through for each future Haskell binary you build.

Thanks for your help, though. It is appreciated. I will post the built tree once I have a working ghc.

Cool. And send in patches too :) -- Don
