So, how do I compile this in GHC? I hoped, that it would be enough to compile all files with the -c option (generating .hi and .o files) and then compiling Main.hs to get an executable program. Howeve, I get the following:
ghc Main.hs [...] ld: fatal: Symbol referencing errors. No output written to a.out
try $ ghc -c Main.hs $ ghc -o ThisIsMyExecutable *.o That is, compile Main.hs also into an .o file, /then/ link the whole thing into an executable...
So, what's wrong, and am I totally on the wrong track... (I studied the GHC User Guide, but could not find the answer to my problem).
normally, one employs `make' for building programs with more than one module, because it keeps track of dependencies (ghc -M *hs) etc. There is a users-guide section on Makefiles for GHC, IIRC.
