I'd like to add a #ifdef to Takusen's Setup.hs, so that we can have a single source file that will compile with ghc-6.6 and ghc-6.6.1. With ghc-6.6 and Cabal-1.1.6.1 we use splitFileName and joinPaths from Distribution.Compat.FilePath. With ghc-6.6.1 (which includes Cabal-1.1.6.2) these have been moved to System.FilePath. I'd like to do something like the following:
#ifdef __CABAL_VERSION__ > 117 import System.FilePath (splitFileName, combine) joinPaths = combine #else import Distribution.Compat.FilePath (splitFileName, joinPaths) #endif
Is something like this possible with Cabal?
No, Cabal does not define any cpp defines like that.
It's either that, or make Takusen's install depend on filepath. I'm not sure which is the least desirable, but I'm open to suggestions.
To be fair, we already require our ghc-6.6 users to upgrade Cabal from 1.1.6 to 1.1.6.1, so making them install filepath instead perhaps isn't so bad, and is no more effort.
I'd got with filepath in that case. Duncan
