Hi, I compiled successful the wxHaskell lib. But when I want to start ghci -package wx following error occurs: Loading package concurrent-1.0 ... linking ... done. Loading package wxcore-0.9 ... linking ... ghc-6.4.20050320: /home/izbifs/scheibe/built/lib/wxcore2.o: unknown symbol `wxcWakeUpIdle' *** Deleting temp files Deleting: ghc-6.4.20050320: unable to load package `wxcore-0.9' I have a running wxHaskell home. Same configuration... wxGtk version, wxhaskell version, same config options except of the prefix. In university it is installed local but I set the LD_LIBRARY_PATH. How can I figure out what's wrong? Can find out where and why the function `wxcWakeUpIdle' is available home and where are the differences? Has anybody a good hint where to start or what to check? Any help is welcome Cheers Patrick PS: Additional informations.. i386 GNU/Linux Fedora gtk+-1.2.10-33 gtk+-devel-1.2.10-33 wxGTK-2.4.2 wxHaskell 0.9 ghc version 6.4.20050320
