Hello, As I have said before I a, "cabalizing" Swish (a semantic web toolkit). I have it built and have run most of the original author's tests by and they pass. There are numerous warnings which seem to be either lack of a function type signature or "unreferenced" symbols ... I will go through one-by-one and clean these up. However, now I am getting the following install-time errors .... any advice on how to track down will be greatly apprecriated .... the following is the result of "cabal build -v": Preprocessing executables for swish-0.2.1... Building swish-0.2.1... /usr/bin/ar: creating dist/build/libHSswish-0.2.1.a Warning: output was redirected with -o, but no output will be generated because there is no Main module. Installing: /home/vigalchin/.cabal/lib/swish-0.2.1/ghc-6.8.2 Installing: /home/vigalchin/.cabal/bin cabal: Error: some packages failed to install: swish-0.2.1 failed during the final install step. The exception was: dist/build/N3Parser/N3Parser: copyFile: does not exist (No such file or directory) vigalchin@ubuntu:~/FTP/Haskell/Swish-0.2.1$ Regards, Vasili
