Re: [HOpenGL] Re: Linker Errors For OpenGL / GLUT 'Hello World' Program

It works for me. I'm running Ubuntu Hardy with some packages built by us at SeeReason (see debs.seereason.com). It looks like ghc can't find your glut libraries (not the Haskell wrappers, but the real GLUT libs). Try 'ghc -v --make ' and look at the linking lines and see what GHC is specifying (mine shows a -lglut). Try compiling an example C program against GLUT and see if that works. My package list looks like this: beshers@blue:~/haskell$ dpkg -l \*glut\* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-f/Unpacked/Failed-cfg/Half-inst/t-aWait/T-pend |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ un freeglut-dev <none> (no description available) ii freeglut3 2.4.0-6 OpenGL Utility Toolkit ii freeglut3-dev 2.4.0-6 OpenGL Utility Toolkit development files un glut-doc <none> (no description available) un glutg3 <none> (no description available) un glutg3-dev <none> (no description available) ii libghc6-glut-d 2.1.1.1-2+3see Haskell GLUT binding for GHC un libghc6-glut-d <none> (no description available) un libghc6-glut-p <none> (no description available) un libglut <none> (no description available) un libglut-dev <none> (no description available) pn libglut3 <none> (no description available) un libglut3-dev <none> (no description available) On Sat, Sep 20, 2008 at 12:10 PM, Donnie Jones wrote:
