Build problems

[robb]

I'm having trouble building documentalist. I've installed llvm 3.3 through homebrew (keg-only).

Then I ran

cabal install --only-dependencies
cabal configure --extra-include-dirs=/usr/local/opt/lvvm/include --extra-lib-dirs=/usr/local/opt/llvm/lib
cabal build

but I got

Building documentalist-0.1...
Preprocessing library documentalist-0.1...
FFI.hsc:8:10: fatal error: 'clang-c/Index.h' file not found

it seems to me that it's not passing the include/lib dir to gcc but I'm not sure how to fix that.

If those are the verbatim commands you ran, you have a typo in the folder name here:

--extra-include-dirs=/usr/local/opt/lvvm/include

Also note that the project currently tries to find LLVM 3.4, though 3.3 might work as well (not sure).

I can confirm 3.3 works for me.

I reinstalled LLVM 3.3 and tried configuring with

cabal configure --extra-include-dirs=/usr/local/Cellar/llvm/3.3/include --extra-lib-dirs=/usr/local/Cellar/llvm/3.3/lib

now I get

$ cabal build
Building documentalist-0.1...
Preprocessing library documentalist-0.1...

dist/build/Text/Documentalist/SourceParser/Clang/FFI.hs:1:1:
    File name does not match module name:
    Saw: `Main'
    Expected: `Text.Documentalist.SourceParser.Clang.FFI'

where dist/build/Text/Documentalist/SourceParser/Clang/FFI.hs is an empty file

I think your system cabal or hsc2hs might be out of date. If so, just update them with cabal install.
