Tim, You write

I'm trying to build DoCon which requires Haskell.

Actually, I now understand the problem better. Haskell requires happy to build. happy requires Haskell to build. (ldl is a compiler switch to haskell /usr/bin/ghc -ldl) So I need to install Haskell before I can build Haskell. I've installed it and am trying to continue the build.

Generally, concerning Glasgow Haskell (ghc) installation and usage, ask glasgow-haskell-users@haskell.org They know GHC and Haskell much better and will help promptly. Explain them what system and processor you have. GHC compiles and `makes' itself. And for the first time, you need to install Glasgow Haskell (ghc) from binary distribution, not from source. Take from http://haskell.org/ghc/ the binary distribution appropriate to your system (Linux, Intel ... ?) DoCon needs version ghc-5.02.2 or ghc-5.02.3 If you have Debian Linux, then install ghc-5.02.2 from the package of Debian distribution. Binary installation does not require the Happy parser to be installed earlier. Then, see install.txt of DoCon. Also I shall help - only, after about April 25. ----------------- Serge Mechveliani mechvel@botik.ru
