Hi Neil,

1) Doesn't work at all, absolutely no signs of life. In fact, the trhxs function never seems to be called.
If I build a minimal project and use your Setup.hs, I get: Preprocessing library Foo-0.1... setup: trhxs not found, cannot process: Foo.xhs (But I am using freshly compiled Cabal-1.1.5 and ghc-6.5, maybe that matters)
2) Even if it did work, now it just errors out when the user doesn't have the appropriate preprocessor half way through the build. Configure should really check for this (how?) and the build shouldn't just call error - it makes it impossible for tools to "figure out" what is missing and provide it.
Yes. My suggestion was incomplete. I think the right way to do this is (when using Simple): * hook configure-step a bit: You should be able to simply append your program description into ConfigFlags.configPrograms and call the default hook. * that will append it into LocalBuildInfo.withPrograms * add the preprocessor to userhooks, but rather than finding executable at that point, take it from LocalBuildInfo.withPrograms I have not done this myself, so I'm not 100% sure HTH, --Esa Ilari Vuokko
