Hi Ertugrul, Compilation problems here: cabal install netwire .... [ 7 of 22] Compiling Control.Wire.Prefab.Simple ( Control/Wire/Prefab/Simple.hs, dist/build/Control/Wire/Prefab/Simple.o ) Control/Wire/Prefab/Simple.hs:15:7: Ambiguous occurrence `force' It could refer to either `Control.Wire.Prefab.Simple.force', defined at Control/Wire/Prefab/Simple.hs:41:1 or `Control.DeepSeq.force', imported from Control.DeepSeq at Control/Wire/Prefab/Simple.hs:24:1-22 cabal: Error: some packages failed to install: netwire-2.0.0 failed during the building phase. The exception was: ExitFailure 1 This build was trying to use deepseq-1.2.0.1. It builds fine with deepseq-1.1.0.2 though. Best, Ozgur
