Hello, All. I made instrumental build which generates profiling information. Cabal's options are: ghc-options:     -Wall                    -O2                    -threaded                    -prof                    -fprof-auto                    -rtsopts                    -fprof-cafs                    "-with-rtsopts=-N -s -h -i0.1 -p -M1G -SMyApplication-S.log" so running application generates files: /MyApplication-S.log, MyApplication.hp, MyApplication.prof/ but in current working directory - which is the problem (also I need to run it on Windows and Linux). Is it possible to specify directory of those output files with some option? Without this I get "Can't open ... file..." due to permission error - Haskell Runtime tries to save all of them in current folder (on Linux and on Windows standard folders for binaries is not allowed for writing, sure). === Best regards, Paul
