Hi Trevor,

I installed llvm with shared libraries:

...

brew install llvm --with-shared-libs

But I now get

...

llvm-general/llvm-general $ git branch git branch llvm-3.8 * llvm-3.9 master

...

cabal configure -fshared-llvm --extra-lib-dirs=/usr/local/opt/llvm/lib --extra-include-dirs=/usr/local/opt/llvm/include Warning: The package list for 'hackage.haskell.org http://hackage.haskell.org/' is 30 days old. Run 'cabal update' to get the latest list of available packages. Resolving dependencies... Configuring llvm-general-3.9.0.0... Warning: Instead of 'cc-options: -I/usr/local/Cellar/llvm/3.9.1/include' use 'include-dirs: /usr/local/Cellar/llvm/3.9.1/include' setup: Missing dependency on a foreign library: * Missing C library: LLVM-3.9.1 This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is.

Perhaps I should report this here: https://github.com/bscarlet/llvm-general/issues? https://github.com/bscarlet/llvm-general/issues?

Hi Dominic,

You need to build/install LLVM with shared libraries.

Then, install llvm-general with -fshared-llvm (or, use my fork, which the stack.yaml files point to).

P.S. On mobile, apologies for the terse reply. On Wed, 22 Feb 2017 at 10:34 AM, Dominic Steinitz mailto:idontgetoutmuch@gmail.com> wrote: I am trying to build accelerate-llvm but getting the ghc panics below. Here’s my config
