I wanted to try out yi after seeing it demonstrated in the Haskell symposium. So, I installed cabal as described here http://hackage.haskell.org/trac/hackage/wiki/CabalInstall I am using Debian unstable with debian distributed GHC 6.8.2.x but it seems that yi requries GHC 6.8.3 to compile. So, I manually installed GHC 6.8.3 using the binary distribution from ghc homepage. When I install yi with "cabal install yi" it succeeds and installs yi version 0.4.6 However, when I run yi it starts but immediately get stuck with the following error message: Custom yi ("/home/kyagrd/.yi/yi-i386-linux") could not be launched! The custom file yi-i386-linux does not exist and I don't have any idea what that is. Same thing happens with the development version 0.4.7 from darcs repository. I did this from complete scratch. I removed the .cabal and .ghc directory and started from scratch in a clean state. If anyone have succeeded using yi in Debian unstable please let me know how you got around from this problem. -- Ahn, Ki Yung
