Hello folks, Christian I'm trying to get ghc 6.8.2 running on Solaris 10 and having problems. To be precise, I'm trying to compile a 'hello world' program by ghc 6.8.2 which I got in binary form haskell.org. gcc is 2.95, it uses sun linker. I remember there were problems with that in the past. Is ghc supposed to work only with gnu ld or sun ld as well? So, how it went first I got compiler errors in many places of Reg.hs: global register variable follows a function definition Googling showed that Don Stewart used to fix it by swapping 2 includes in Stg.h - putting MachRegs.h after Regs.h instead of before. It helped Then there was assembler error: cannot use v8plus instructions in a non-v8plus target binary It was caused by -mcpu=v9, which ghc passes to gcc. I blindly added -optc -mcpu=v8 and it helped :) Then the linker complained that it could not resolve aio_fork and __aio_suspend64, referenced from librt.so. -lrt is passed by ghc to the linker. On this machine there is /lib/libaio.so. Linking with it didn't help. It doesn't really contain exactly those functions, only with slightly different names, like _aio_forkinit, _libaio_fork. Also, librt which was linked in was the one lying close to where gcc is installed. Apart from that, there is also librt.so in /lib. I thought, maybe the wrong librt was used and said -optl -L/lib to link against the one in /lib. No complaints, but the resulting binary segfaults. Does anybody have any ideas? -- Daniil Elovkov
