[originally sent to ports, resending to hackers at the suggestion of someone on that list.] Hi Folks, 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? 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. Any thoughts greatly appreciated. I'm not on this list, BTW. Cheers, Simon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
