Greetings fellow Haskellers and other readers,
During my ongoing research on "doing whatever I feel like", I discovered that using C++ libaries in GHCi (no problems with GHC) wasn't as pleasant as I had hoped. Apparently C++ sources requires to be linked with crtbegin.o and crtend.o (and others?) and I was wondering how to solve this nicely. Any hints or pointers would be greatly appreciated.
How about creating a dummy ghc package that has no Haskell code but specifies all the nasty link time options. i.e. using the extra_libraries, extra_ghc_opts, extra_cc_opts and extra_ld_opts fields.
Then when compiling your program you just use -package c++ or (-package "cpp" or "cpp-support" if "c++" is not a valid package name). if you make packages that depend on C++ support it's still easy, just make the new package depend on the "cpp" package.
Thanks for replying and it all sounds nice, but I'm not sure which linker options I'm missing since the location of the crt*.o files appears to be implementation specific. -- Friendly, Lemmih
