I do use template haskell for deriving binary instances for some data
getting proper version tags. But shouldn't touch llvm parts at all.
The cabal file is
as basic as it gets. If I drop template-haskell (and with it pretty
large part of my program)
cabal does not complain.
LLVM library does not in general work in ghci, but how does this affect cabal?
Simple work-around is to make a monolithic .so/dylib out of LLVM and modify
LLVM bindings package to use that instead of linking to .a files.
(Either by hand
or using svn version on llvm that supports ./configure
--enable-shared). This is
rather lot of work though.
