Hi, After creating my stub objects etc using GHC, I'm trying to create a library with a C interface to some Haskell functions. I'm explicitly passing in -no-hs-main yet the linker still fails due to missing main? I'm sure I've had this working before with a slightly simpler example, but can't work out what is wrong here. If I give it a main (to humor it - it's not a solution), then it links and produces an executable - so it looks to me like I'm not telling the linker what I want correctly? Any ideas? Cheers, Phil. ghc -O2 --make -no-hs-main -package mtl -package array -optl '- shared' FFI/Octave/MyInterface.c FFI/Octave/OptionInterface_stub.o FFI/ Octave/OptionInterface.o ./FrameworkInterface.o ./Maths/Prime.o ./ MonteCarlo/DataStructures.o ./MonteCarlo/European.o ./MonteCarlo/ Framework.o ./MonteCarlo/Interface.o ./MonteCarlo/Lookback.o ./Normal/ Acklam.o ./Normal/BoxMuller.o ./Normal/Framework.o ./Normal/ Interface.o ./Random/Framework.o ./Random/Halton.o ./Random/ Interface.o ./Random/Ranq1.o -o FFI/Octave/libMyInterface.so Linking FFI/Octave/libMyInterface.so ...
