Hi everyone, I am trying to build GHC 6.8.3 from source in a slightly nonstandard environment (mostly with regard to the filesystem). The build setup, however, is fairly standard (32-bit x86 RHEL, gcc 3.4, glibc 2.3). I managed to get the bootstrap installation from the "ghc-6.6.1-x86_64-unknown-linux" tarball (downloaded from http://www.haskell.org/ghc/download_ghc_661.html#x86linux) working without much trouble. Now I'm trying to use that to build 6.8.3 from source. But I am hitting an error in the build target, apparently for this rts component. Output snippet here: http://hpaste.org/10252 The first of the ghc errors is "RtsFlags.c:1120:1: directives may not be used inside a macro argument" which is followed by many more (I think this is the real cause though). I searched around and it seems like a gcc "limitation" (not supporting something that is not part of the C standard but people still wanted). But even then it has supposedly been supported since gcc 3.2, and I'm using 3.4. To be honest, I don't know anything about the interaction between ghc and gcc at this juncture so I'm a bit in the dark. Any advice is appreciated. I can also provide more complete output/details if it would be useful. Thank you!
