* Simon Marlow (simonmar@microsoft.com) [990912 13:05]: >I'd like to make a port for our Haskell compiler, GHC (see >http://research.microsoft.com/users/t-simonm/ghc). There are some subtle >problems with this: > > - GHC depends on itself. That is, you need GHC > installed in order to build GHC. > - GHC depends on Happy, our parser generator. > - Happy depends on GHC (it's written in Haskell). >So, one solution would be to provide a binary port, say ghc-bin, which would >install a binary distribution. I checked the modula-3 port, and it doesn't >seem to have a binary port, so what's the accepted way of doing this? Well, you could also take a peek at net/cvsup-bin Another binary used a lot. It might give some ideas. >It's possible to bootstrap GHC from intermediate C files, but it's a bit >fiddly and I'd prefer not to do this if possible. However, one thing that >occurs to me is that the port could bootstrap itself from C if you say 'make >BOOTSTRAP=YES', and otherwise attempt to build using an installed GHC. *nod* That could be a solution. Although it requires a clue. Normally one does: make make install make clean What could be a solution would be to make and after the make go interactive and ask to try to bootstrap from C or use the GHC-binary. print/apsfilter is a good example of interactive stuff... >Any thoughts greatly appreciated. These are just some random thoughts. Surely I am missing some pitfalls, but these might spark some ideas. -- Jeroen Ruigrok van der Werven/Asmodai asmodai(at)wxs.nl The BSD Programmer's Documentation Project <http://home.wxs.nl/~asmodai>; Network/Security Specialist BSD: Technical excellence at its best If I am telling you the Truth now, do you believe it?
