Hi,
I'd like to convert Yhc to use Cabal. This presents several challenges:
* We would like to depend on fps/base depending on compiler version. Configurations will allow this.
* We have the library Yhc.Core in our tree which is developed in parallel with Yhc. What would be nice is to have a Yhc.Core library which we don't have to explicitly install each time. I guess having all the Yhc.Core files in both the library, and again in the program would work.
* We'd ideally like multiple cabal files in one directory - for things like ycr2js, yhc, yhi etc.
* Can Cabal compile C files? Can it do things like testing the size of int/long etc?
* Is cabal-install ready for serious use? If so we would like to use this as our primary method of compilation.
I suspect that it will not be possible to move entirely to Cabal initially - but perhaps Yhc can point out features that Cabal lacks.
I beleive that the best approach would be to split the York build system into separate build systems for yhc/yhi/etc. Yhi, being a pure C program, can use a system designed for pure C, such as autotools. Yhc, being pure Haskell, would be a much better fit for Cabal than the York toolchain currently is considered as a whole. Stefan
