Hi Mark,<br><br>When I was on Windows, I had to get the sources of the OpenGL and GLUT packages add an &quot;extra-libraries&quot; line to each of <a href="http://OpenGL.buildinfo.in">OpenGL.buildinfo.in</a> <a href="http://GLUT.buildinfo.in">GLUT.buildinfo.in</a>.  Seems to be a bug in the recent library releases.  For GLUT, I think I added<br>
<br>extra-libraries: glut32<br><br>I forget what the library name was for OpenGL.<br><br>To find out whether these extra-libraries are already listed, try the following shell commands:<br><br>ghc-pkg describe OpenGL | grep extra<br>
ghc-pkg describe GLUT | grep extra<br><br>I was completely stumped until Sigbjorn Finne suggested there might be missing extra-libraries.<br><br>  - Conal<br><br><div class="gmail_quote">2009/3/17 Mark Spezzano <span dir="ltr">&lt;<a href="mailto:mark.spezzano@chariot.net.au">mark.spezzano@chariot.net.au</a>&gt;</span><br>

<p>Hi,</p>

<p> </p>

<p>Can someone PLEASE help me to understand exactly how to
configure OpenGL on Window using Haskell. I&#39;m using Eclipse IDE.</p>

<p> </p>

<p>When I try to run the file Test1.hs in GHCi then I get the
following error:</p>

<p>Loading package syb ... linking ... done.</p>

<p>Loading package base-3.0.3.0 ... linking ... done.</p>

<p>Loading package array-0.2.0.0 ... linking ... done.</p>

<p>Loading package containers-0.2.0.0 ... linking ... done.</p>

<p>Loading package OpenGL-2.2.1.1 ... can&#39;t load .so/.DLL for:
GL (addDLL: could not load DLL)</p>

<p>Prelude Main&gt; </p>

<p> </p>

<p>I&#39;ve copied the GLUT dll into Windows/System32.</p>

<p> </p>

<p>Is there some flag or option that I need to enable to tell
Haskell where to go to link in the library. What do I do with the other .h and
.lib files from GLUT?</p>

<p> </p>

<p>Thanks</p>

<p> </p>

<p>Mark</p>
