So, you might need to -- upgrade hsx -- make sure that the upgraded trhsx executable is the one being executed by cabal install hsx (maybe deleting/temporarily moving other trhsx exes)
Unfortunately, this suggestion didn't work out for me. I read through all the relevant GHC documentation I could find -- I didn't see a way to set a specific path for GHC to search through for binaries. Whether I moved trhsx or not, the error was the same. But it's the only trhsx on my system. I've upgraded through every version of hsx that is compatible with Happstack, and tried every hsp that is compatible with Happstack. I've built Cabal-install, removed it, used the Arch package; tried global/user installs for Happstack; did a darcs get on the official Happstack repo, and tried to build using its build script, on a fresh GHC install; and other stuff that I guess didn't make much sense. It always broke in the same place: [ ajs@kizaru:~/ ]$ cabal install hsp-0.4.5 Resolving dependencies... Configuring hsp-0.4.5... Preprocessing library hsp-0.4.5... Building hsp-0.4.5... ghc: could not execute: trhsx cabal: Error: some packages failed to install: hsp-0.4.5 failed during the building phase. The exception was: ExitFailure 1 The strange thing about it (that I noticed) is that GHC reports failing during the building phase instead of the preprocessing phase. Maybe this is just an artifact of the logging system, but it seems like GHC is doing something strange. If I increase the verbosity, (near the end) I get: *** Haskell pre-processor: trhsx src/HSP/HJScript.hs /tmp/ghc6345_0/ghc6345_6.hscpp /tmp/ ghc6345_0/ghc6345_0.hspp *** Deleting temp files: Deleting: /tmp/ghc6345_0/ghc6345_0.hspp /tmp/ghc6345_0/ ghc6345_6.hscpp /tmp/ghc6345_0/ghc6345_5.hscpp /tmp/ghc6345_0/ ghc6345_4.hscpp /tmp/ghc6345_0/ghc6345_3.hscpp /tmp/ghc6345_0/ ghc6345_2.hscpp /tmp/ghc6345_0/ghc6345_1.hscpp /tmp/ghc6345_0/ ghc6345_0.hscpp Warning: deleting non-existent /tmp/ghc6345_0/ghc6345_0.hspp *** Deleting temp dirs: Deleting: /tmp/ghc6345_0 ghc: could not execute: trhsx /usr/bin/ghc returned ExitFailure 1 cabal: Error: some packages failed to install: hsp-0.4.5 failed during the building phase.
