With a base system with just ghc and cabal-install, if I try to install bytestring-lexing I get:
$ cabal install bytestring-lexing Resolving dependencies... Configuring bytestring-lexing-0.4.0... cabal: The program alex version >=2.3 is required but it could not be found. cabal: Error: some packages failed to install: bytestring-lexing-0.4.0 failed during the configure step. The exception was: ExitFailure 1
The cabal file for bytestring-lexing contains
Build-Tools: alex >= 2.3
Is there any way to make the cabal install of bytestring-lexing force the install of alex first?
no, cabal-install does not automatically install build-tools at all, only Cabal checks them for compilation. I guess the reason is that build-tools needs to be put on the PATH, and that is beyond the scope of cabal-install.
