Hello, Your version of ghc is too old. Please consider update it. The catch was moved from one module to the other. It's considered as a bug that was fixed.
I have installed it on ghc-7.6.3 and now on ghc-7.8.3. Anton PS . The catch is usefull for windows users to stop program with Ctrl+C. 2014-11-02 22:56 GMT+04:00 L_y_su_c <masinstrumentosmusica...@gmail.com>: > When i try to install csound-expression, this error occurred: > > [15 of 23] Compiling Csound.IO ( src/Csound/IO.hs, > dist/build/Csound/IO.o ) > > src/Csound/IO.hs:229:5: > Ambiguous occurrence `catch' > It could refer to either `Prelude.catch', > imported from `Prelude' at > src/Csound/IO.hs:23:8-16 > (and originally defined in `System.IO.Error') > or `Control.Exception.catch', > imported from `Control.Exception' at > src/Csound/IO.hs:42:1-24 > (and originally defined in > `Control.Exception.Base') > cabal: Error: some packages failed to install: > csound-expression-4.1.0 failed during the building phase.
