llvm-ffi: FFI bindings to the LLVM compiler toolkit.

FFI bindings to the LLVM compiler toolkit.

Installation cannot be done fully automatically. It would require Cabal code that is bound to certain Cabal versions and is prone to fail. We give several non-automatic ways that also allow you to choose a particular LLVM version.

First possibility is to point Cabal to the LLVM installation directories manually. On Ubuntu this would look like this:

cabal install --extra-include-dirs=/usr/lib/llvm-9/include --extra-lib-dirs=/usr/lib/llvm-9/lib llvm-ffi

For cabal new-build this does not work, because every package build is bound to all influencing flags. That is, if you build, say llvm-tf, it depends on llvm-ffi without the extra-lib-dirs flag. In order to solve this problem, you may specify the extra directories in the global Cabal configuration. I.e. you may add the following lines to .cabal/config:

extra-include-dirs: /usr/lib/llvm-9/include
extra-lib-dirs: /usr/lib/llvm-9/lib

You can store such paths permanently in a pkg-config file like llvm.pc. The optimal way would be if LLVM installations or GNU/Linux distributions would contain such a file, but they don't. Instead, you may generate it using the llvm-pkg-config package or write one manually. Then you run

cabal install -fpkgConfig

We try to stay up to date with LLVM releases. The current version of this package is compatible with LLVM 3.9-9. Please understand that the package may or may not work against older LLVM releases.

Warning for inplace builds: Re-configuring the package using, say -fllvm600, and re-buildung it might result in corrupt code. You must make sure that the stuff in cbits is re-compiled. Cabal or GHC may forget about that. You are safe if you run cabal clean.
