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' 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?

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.

If anyone has any ideas, I’d be very grateful.
