I got the following error message trying to install git-annex:
|
|
|
|
cabal: cannot configure git-annex-3.20120418. It requires base >=4.5 && <5
|
|
For the dependency on base >=4.5 && <5 there are these packages: base-4.5.0.0.
|
|
However none of them are available.
|
|
base-4.5.0.0 was excluded because of the top level dependency base -any
|
|
|
|
These are the steps I performed to make it work
|
|
|
|
1. Download [Ghc 7.4](http://www.haskell.org/ghc/download).
|
|
2. Run `sudo cabal install git-annex --bindir=$HOME/bin`.
|
|
3. Compilation of the Crypto-4.2.4 dependency failed since it's not updated to work with Ghc 7.4. You need to patch SHA2.hs (steps below).
|
|
4. Run `sudo cabal install git-annex --bindir=$HOME/bin` a second time.
|
|
|
|
The steps I did to patch the SHA2.hs file in Crypto-4.2.4:
|
|
|
|
1. `cabal unpack crypto-4.2.4`
|
|
2. `cd Crypto-4.2.4`
|
|
3. `patch -p1 < crypto-4.2.4-ghc-7.4.patch`
|
|
4. `sudo cabal install`.
|
|
|
|
PS: I used [this patchfile](http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/dev-haskell/crypto/files/crypto-4.2.4-ghc-7.4.patch?revision=1.1).
|
|
Then I did the last step a third time.
