Re: [Haskell-cafe] GHC RTS question

Supply a fix for the problem, and it will probably get included. There has probably been little demand for this feature so far. -- Lennart On Sun, Feb 21, 2010 at 10:21 PM, Ben Millwood wrote:

You might be able to get somewhere by writing a custom "main" function in C and linking it in. According to http://haskell.org/ghc/docs/latest/html/users_guide/options-phases.html if a lib specified with the -l option during compilation contains a "main", that will be used in preference to the one from HSrts.

I think the neater way of doing this would be to use the FFI, with a foreign export declaration making your haskell main available to a wrapper C file, which would then initialise the RTS with a slightly-modified argc and argv. See http://www.haskell.org/ghc/docs/latest/html/users_guide/ffi-ghc.html for details on how to do that.

I also think it's strange, though, that adding RTS hooks is not optional. GHC should support some method of disabling them, in my opinion. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
