cabal-install-ghc74 fixes

Greetings, I was doing a clean, from scratch install of ghc-7.4.1 and was trying to get cabal-install to work, and since I am new I tried to do all the bootstrap.sh stuff myself. After failing and starting over I saw this package (cabal-install-ghc74) and gave it a shot. Unfortunately with a fresh install there are three things wrong. 1. It was not checking for the right .cabal file. 2. network-2.3.0.5 has the restriction of base <4.5, ghc-7.4.1 ships with base 4.5 so bootstrap.sh fails. Using the latest version (2.3.0.13 at time of writing) solved that issue. 3. HTTP-4000.1.2 has the same restriction as the previous (base <4.5). I just used HTTP-4000.2.3 instead. This builds cabal correctly on my x86_64 Debian stable box. I don't know how I am supposed to do this, but I just attached a diff if that helps. Thanks === BEGIN DIFF === 50c50 < NETWORK_VER="2.3.0.5"; NETWORK_VER_REGEXP="2\." # == 2.* --- > NETWORK_VER="2.3.0.13"; NETWORK_VER_REGEXP="2\." # == 2.* 54c54 < HTTP_VER="4000.1.2"; HTTP_VER_REGEXP="4000\.[01]\." # == 4000.0.* || 4000.1.* --- > HTTP_VER="4000.2.3"; HTTP_VER_REGEXP="4000\.2\." # == 4000.2.* 69c69 < grep "cabal-install-ghc72" ./cabal-install-ghc72.cabal > /dev/null 2>&1 \ --- > grep "cabal-install-ghc74" ./cabal-install-ghc74.cabal > /dev/null 2>&1 \ === END DIFF === PS: There are a lot of emacs temp files (~) in this tarball as well. I don't know what the policy is on removing them or if anyone cares.

Heads up: importing the Cabal issue tracker to github next week
by Bryan O'Sullivan 17 May '12

17 May '12

I am planning on doing this early next week, probably in two phases. As part of the import process, github will generate a *lot* of notification emails. I'm afraid there is nothing I can do to stem the tide, as github does not provide a mechanism to suppress these. If you have a github account, please brace yourself.

#953: Alex-generated Lexer isn't found when building test-suite ----------------------------+----------------------------------------------- Reporter: owst | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.14.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- I'd like to use my Alex-generated lexer in my test-suite. I've tried adding other-modules/build-tools to my test-suite section, but upon building the Lexer module isn't found. I've got no problems using the lexer within my normal executable. Should I be able to use my Lexer in the test-suite? I'll attach a fairly minimal example, the Main module and the TestSuite module both use the Lexer, Main will compile, TestSuite won't: $ cabal configure --enable-tests $ cabal build [... blurb] Preprocessing test suite 'tests' for test-suite-with-alex-0.0... tests/TestSuite.hs:7:8: Could not find module `MyLexer' Perhaps you meant Lexer (needs flag -package ghc-7.4.1) Use -v to see a list of the files searched for. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/953> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
