I installed GHC 6.10.4 (as ./configure said it was required) from a .bz2 file on the GHC downloads page. I then tried ./configure for the platform again, and got: checking ghc actually works... no configure: error: Your installation of ghc does not appear to work. It cannot compile a simple program (see config.log for the details). If you installed ghc from a generic binary tarball then it is worth checking that you have the 'gmp' C library and header files installed. (On debian-based systems this package is called libgmp3-dev.) Looking in config.log, I see: configure:2287: checking ghc actually works configure:2296: /usr/local/bin/ghc -o conftest conftest.hs /tmp/ghc22651_0/ghc22651_0.s: Assembler messages: /tmp/ghc22651_0/ghc22651_0.s:43:0: Error: suffix or operands invalid for `push' /tmp/ghc22651_0/ghc22651_0.s:89:0: Error: suffix or operands invalid for `push' /tmp/ghc22651_0/ghc22651_0.s:135:0: Error: suffix or operands invalid for `push' configure:2299: $? = 1 configure: failed program was: main = putStr "Hello world!\n" -- this file generated by TRY-COMPILE-GHC end of failed program. configure:2308: result: no configure:2314: error: Your installation of ghc does not appear to work.

If you installed ghc from a generic binary tarball then it is worth checking that you have the 'gmp' C library and header files installed. (On debian-based systems this package is called libgmp3-dev.) Libgmp is installed. I don't know the significance of the assembler error messages. If I type from the command line: ghci I get the Prelude> prompt, so it looks like the installation is OK at first glance. What should I check next? -- Colin Adams Preston Lancashire
