I'm trying to install GHC 6.10.1 on Mac OS X 10.5 (PowerPC). I installed Xcode 3.1.2. I built libgmp 4.2.4 and installed it in /usr/local/lib. When I do "./configure" in GHC's dist directory, however, I get: bash-3.2$ ./configure checking build system type... powerpc-apple-darwin9.6.0 checking host system type... powerpc-apple-darwin9.6.0 checking target system type... powerpc-apple-darwin9.6.0 Which we'll further canonicalise into: powerpc-apple-darwin checking for path to top of build tree... dyld: Library not loaded: /usr/local/lib/libgmp.3.dylib Referenced from: /Users/family/Desktop/Downloads/ghc-6.10.1/dist/utils/pwd/pwd Reason: no suitable image found. Did find: /usr/local/lib/libgmp.3.dylib: mach-o, but wrong architecture /usr/local/lib/libgmp.3.dylib: mach-o, but wrong architecture configure: error: cannot determine current directory Any ideas what I'm doing wrong? Thanks.
