installation failed

[Luis Silvestre]

I have zero experience with Haskell. I use Ubuntu 12.04.

I tried to install with cabal following the standard instructions but poppler installation failed. Then I tried the command 

cabal install -f-poppler hxournal

which looked equivalent to the method described on the website to disable poppler. I didn't get any poppler error, but the compilation of xournal-builder failed. It claims to encounter some ambiguity between a definition of '<>' in the file Builder.hs with another definition imported from Data.Monoid.

Any help?

This is the output I am getting.

luis@luis-laptop:~$ cabal install -f-poppler hxournal

[Ian-Woo Kim]

Hi,

That is due to incompatibility between base library of ghc-7.0 and
ghc-7.4. I just uploaded a new patch-level version of xournal-builder
and hxournal. You need to update your cabal database and try to
install it again.
