Greetings from Canada, I installed Christian Maeder's binary package for the Glasgow Haskell Compiler (ghc-6.4.1-sparc-sun-solaris2.tar.gz) which I downloaded from http://www.haskell.org/ghc/docs/6.4.1/html/users_guide/release-6-4-1.html When I compiled a simple program, I got an error. ghc -o hello hello.hs In file included from /usr/local/lib/ghc-6.4.1/include/RtsAPI.h:16, from /usr/local/lib/ghc-6.4.1/include/RtsExternal.h:14, from /usr/local/lib/ghc-6.4.1/include/Stg.h:161, from /tmp/ghc25804.hc:3: /usr/local/lib/ghc-6.4.1/include/HsFFI.h:32:20: stdint.h: No such file or directory A bunch of config files in /usr/local/lib/ghc-6.4.1/include defined HAVE_STDINT_H which does not work on Solaris. I replaced the offending definition with the following. /* #undef HAVE_STDINT_H */ Recompiled without error and the program runs. All seems well.
