Unable to upgrade cabal to the latest version in Linux - linux

Question

I'm trying to upgrade cabal to the latest version because the current version has a bug:
cabal --version
cabal-install version 1.16.0.2
using version 1.16.0 of the Cabal library
which cabal
/usr/bin/cabal
curl http://hackage.haskell.org/package/cabal-install-1.22.3.0/cabal-install-1.22.0.3.tar.gz
tar xvfz cabal-install-1.22.3.0.tar.gz
cd cabal-install-1.22.3.0
cabal install
It seems to install cabal 1.22.3.0 in ~/.cabal but there's no bin directory in it, there're only share, packages, logs, lib directories and I can't find executable in the folder.
So can I find the new cabal which I've just installed?
UPDATE:
cabal update
cabal install cabal-install

Answer 1

Currently in ghc-7.10 there seems to be no way to upgrade cabal-install from 1.16 (which it is shipped with and reverts to when deleting .ghc).
Workaround:
install ghc-7.8 and
upgrade cabal-install
switch back to ghc-7.10
https://mail.haskell.org/pipermail/haskell-cafe/2014-December/117512.html
Luckily for me, I already had a script ready for switching versions globally:
#!/bin/bash -e
if [ $# -ne 1 ]; then
echo "usage: $0 <version> \# e.g.: $0 7.8.3 - being run for example in /usr/local/bin"
exit 1
fi
VERSION=$1
sudo rm ghc
sudo ln -s ghc-${VERSION} ghc
sudo rm ghci
sudo ln -s ghci-${VERSION} ghci
sudo rm ghc-pkg
sudo ln -s ghc-pkg-${VERSION} ghc-pkg
sudo rm haddock
sudo ln -s haddock-ghc-${VERSION} haddock
sudo rm runghc
sudo ln -s runghc-${VERSION} runghc
(May need adjustment depending on your ghc install.)

Answer 2

Try installing it using cabal itself:
cabal update
cabal install cabal-install

Answer 3

After running either cabal install or cabal build, look in ./dist/build/cabal/ for the built cabal binary.
You can also use this recipe:
cabal get cabal-install
cd cabal-install-1.22.4.0 # or whatever the get command says
cabal build
# binary resides in dist/build/cabal
