Packages build locally but fail to build on hackage server

[ivanperez-keera]

Packages fail to build on the hackage server itself, apparently due to issues with dependencies. From the build log on Hackage:

/bin/sh: 1: bnfc: not found

I believe the solution to this rests in adding build-tool-depends: to each section that needs bnfc, alex and happy in the cabal files. Changes to the Setup.hs files may also be necessary (or adding those sections may simplify things).

There's also an option to indicate that some files are being automatically generated.
