Now, when I invoke the program on my computer, it does what it should do: (...) However, when I run the program on a different computer, I get the following: (...) [thomas@... ~] $ ./count count.hs count: timer_create: Invalid argument
I don't know where time_create is exactly used here, however, it seems like a linking problem. Have you tried rebuilding your program in the remote machine? Actually, the fact that other programs did succeed seems strange to me. You could show some program that did work on both machines if you want to know why it actually worked. If you don't want to rebuild, why not to use it as a script? You can do it by just adding this first line to your file: #!/usr/bin/runhaskell and allowing it to be used as a script: chmod a+x count.hs I usually add such scripts to ~/bin so I can run then anywhere (but check if your distribution do add ~/bin to path).
