Hi, I'm currently working on a project where it would save me a lot of time if I could use the FFI's 'foreign export'-statement, enabling me to call Haskell-functions from C. Unfortunately, I can't get it to work... After reading about various tools and compilers and experimenting with some, I came to the conclusion that the most (and perhaps only) viable option would be to use HDirect in combination with the Glasgow Haskell Compiler. But even the most simple example, exporting Int -> Int-functions, (which doesn't even appear to use the HDirect library) just won't work. When using ghc-4.08.2 everything compiles and links just fine, but when running the result I get an 'Illegal instruction' error (RedHat Linux 7.1) or a 'Segmentation Fault' under Solaris 8. When using ghc-5.00.2 the object files are created, but I get the following error when linking (using ghc-5.00.2 -fglasgow-exts -static -no-hs-main -i../../lib -L../../lse -lhdirect -o tst tst.o libHStst.a, see the HDirect server-example): Undefined first referenced symbol in file Main_main_closure /home/rdehaan/ghc/lib/ghc-5.00.2/libHSstd.a(PrelMain__2.o) __init_Main /home/rdehaan/ghc/lib/ghc-5.00.2/libHSstd.a(PrelMain__1.o) ld: fatal: Symbol referencing errors. No output written to tst Has anyone else succeeded in exporting Haskell-functions and using them in C-modules under Linux or Unix? Any help would be appreciated!
