You want the ghc settings file. Make sure you point it to the absolute path. On Thursday, March 6, 2014, Charles-Pierre Astolfi wrote:

Since you use brew, I'll assume you're using osx.

I had the same problem a few weeks ago. Here's how I solved it (be advised, it's an ugly hack): 1. Download llvm from the official website (binaries or source). If you download the source compile it. 2. Put all of the files somewhere you find convenient (I use ~/.llvm) 3. Edit ghc.conf (not sure if the name is correct), to add ~/.llvm/bin/llc (in my case) and ~/.llvm/bin/llvm where required. I don't remember the path, somewhere in lib in think. It's the file that is read when running ghc --info

It should work afterwards. Note that llvm3.4 is the latest llvm but is not tested on ghc (llvm3.3 is). I use 3.4 w/o issues though.

Hi, please can you help me with following: I'm unable to install gloss-raster. Output is:

dev$ cabal install gloss-raster Resolving dependencies... Configuring gloss-raster-1.8.1.2... Building gloss-raster-1.8.1.2... Preprocessing library gloss-raster-1.8.1.2... [1 of 2] Compiling Graphics.Gloss.Raster.Array ( Graphics/Gloss/Raster/Array.hs, dist/build/Graphics/Gloss/Raster/Array.o )

llvm seems to be installed:

$ brew install llvm Warning: llvm-3.3 already installed

cheers, m.

llc is not llvm-gcc (and even if it were, the leading / on /usr/bin is not optional). If you have LLVM installed via brew, you are probably looking for /usr/local/bin/llc and /usr/local/bin/opt for those two. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

Many thanks! It turned out that llc and opt is installed in: usr/local/Cellar/llvm/3.3/bin/ After changing ghc settings, gloss-raster installed correctly ;-) Thanks m.
