Works fine! But when I try to load a module using it in ghci, and run an function (which is unrelated to the FFI bindings) I get:
/lib/hsVigraRF-0.1.0.0/ghc-7.**6.2/HShsVigraRF-0.1.0.0.o: unknown symbol `_ZGVZN5vigra10rf_**defaultEvE6result'
_ZGVZN5vigra10rf_**defaultEvE6result is a symbol from vigra. So why do I get this in ghci and not when compiling/running? What can I do about this?
Becaue ghci's symbol resolution is an ugly hack in released versions of ghc. The next ghc release redoes ghci to use the system linker instead of a built-in hack, and fixes many of these issues; you can wait for its release or build ghc HEAD. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
