Hello, I'm trying to write a 3D renderer in Haskell using SDL bindings (Lemmih) and OpenGL bindings. When I try to compile my work, ghc runs collect2: /usr/libexec/gcc/i686-pc-linux-gnu/3.4.3-20050110/collect2 --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o a.out -u GHCziBase_Izh_static_info -u GHCziBase_Czh_static_info -u GHCziFloat_Fzh_static_info -u GHCziFloat_Dzh_static_info -u GHCziPtr_Ptr_static_info -u GHCziWord_Wzh_static_info -u GHCziInt_I8zh_static_info -u GHCziInt_I16zh_static_info -u GHCziInt_I32zh_static_info -u GHCziInt_I64zh_static_info -u GHCziWord_W8zh_static_info -u GHCziWord_W16zh_static_info -u GHCziWord_W32zh_static_info -u GHCziWord_W64zh_static_info -u GHCziStable_StablePtr_static_info -u GHCziBase_Izh_con_info -u GHCziBase_Czh_con_info -u GHCziFloat_Fzh_con_info -u GHCziFloat_Dzh_con_info -u GHCziPtr_Ptr_con_info -u GHCziPtr_FunPtr_con_info -u GHCziStable_StablePtr_con_info -u GHCziBase_False_closure -u GHCziBase_True_closure -u GHCziPack_unpackCString_closure -u GHCziIOBase_stackOverflow_closure -u GHCziIOBase_heapOverflow_closure -u GHCziIOBase_NonTermination_closure -u GHCziIOBase_BlockedOnDeadMVar_closure -u GHCziIOBase_BlockedIndefinitely_closure -u GHCziIOBase_Deadlock_closure -u GHCziWeak_runFinalizzerBatch_closure -u __stginit_Prelude /usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110/../../../crt1.o /usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110/../../../crti.o /usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110/crtbegin.o -L/home/yin/devel/third/sdlh/SDLstable/img/lib/SDL-0.2.0 -L/usr/lib/ghc-6.4 -L/usr/lib -L/usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110 -L/usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110 -L/usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110/../../../../i686-pc-linux-gnu/lib -L/usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110/../../..

What have I to do or where have to look in to find and resolve the problem? I use Gentoo 2005.0 and SDL binding from SDLStable brach installed by hand (I didn't use Portage). Is it the packages.conf file, where propably is the problem? Thanks for every answer... Matej 'Yin' Gagyi
