cabal version should be included as an requirement in somewhere

I got this yesterday in a clean installation of fedora 24.

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.8.4
$ cabal --version
cabal-install version 1.18.1.0
using version 1.18.1.5 of the Cabal library 
$ agda --version
Agda version 2.6.0.1-5893007
$ pwd
/home/hotel/apia
$ make install-bin
cabal install --disable-documentation

Configuring apia-1.0.1...
Failed to install apia-1.0.1
Last 10 lines of the build log ( /home/hotel/.cabal/logs/apia-1.0.1.log ):
cabal: Error: some packages failed to install:
apia-1.0.1 failed during the configure step. The exception was:
user error (
Setup.hs:25:5:

‘PackageName(PackageName, unPackageName)’
)
Makefile:490: recipe for target 'install-bin' failed
make: *** [install-bin] Error 1

After upgrade cabal to the version 1.24, the issue above disappeared.

I'll fix it.

[jonaprieto]

What about adding the version for cabal-install in the apia.cabal?

[asr]

No. We need to added a dependence on the Cabal library (no cabal-install).

Travis jobs with GHC 7.8.4 and 7.6.3 are failing.

The revert closed the issue.

[asr]

The previous fix was wrong because Setup.hs doesn't use the dependencies in apia.cabal. A proper fix could use CPP in Setup.hsbut it is not working and I'm testing...

[jonaprieto]

I see.

CPP in Setup.hs works with GHC 8.0.2 but doesn't work with GHC 7.8.4. I'll try a different solution...
