I've been unable to figure out how to build Cabal with Hugs 2006.09.04:

$ runhugs -98 Setup configure --hugs --prefix=/usr runhugs: Error occurred ERROR "./Distribution/Compat/ReadP.hs":70 - Syntax error in module definition (unexpected selector "#if")

The README file is GHC-centric, so I'm at a bit of a dead end. Do you have any suggestions?

I'm not sure how it was ever supposed to work, that is bootstrapping Cabal directly using runhugs on the Setup.hs script in the Cabal dir. Cabal has always had some cpp in it and (as far as I know) hugs does not have a -cpp flag. I presume the hugs build system has some workaround to cpp all the files first. The way I've tested it recently is to build the Setup.hs with ghc and use that to install Cabal for hugs. From then on one can use runhugs to run other Setup scripts. If you can get the search path right (ie to not look in the current dir) then I expect it would also be possible to bootstrap using a pre-existing Cabal library for hugs. Duncan
