link errors on Ant build (newbie to building)

OpenGL Development JOGL Development
#1

I’m trying to build JOGL because the newest version on CVS has a bug fix I need, but my build stops with this:

   [cc] Starting link

Any idea what I’m doing wrong? I have the path variables set up correctly I think, and I’m running from a Visual Studio .NET 2003 command prompt. I have Ant 1.6.2, ANTLR 2.7.2, and of course MS VS.NET 2003, version 7.1.3
Microsoft Visual C++ .NET 69462-335-0000007-18740

Thanks so much.

I haven’t built JOGL with VS.NET but it looks like you may need to update the vc7.root property in your $HOME/jogl.properties file and compile with “ant win32.vc7”. It looks like the link process is not finding the import library opengl32.lib.

Thank you! The problem was that jogl.properties says:

If you are building on Windows with Visual C++ 7.0 and have installed

the compiler in somewhere other than the default location, modify this

to point to the absolute path of the VC98 directory

vc7.root=C:/Program Files/Microsoft Visual Studio .NET/Vc7

but for VS.NET 2003 it needs:

vc7.root=C:/Program Files/Microsoft Visual Studio .NET 2003/Vc7/PlatformSDK rather than just
vc7.root=C:/Program Files/Microsoft Visual Studio .NET 2003/Vc7

I wonder if that’s the case for VS.NET non-2003?

It might be good to change the comments, too - we really want to point to the absolute path of the parent of the library directory, if one can say that any more clearly…

Thanks again.

Thanks for the note; I’ve updated the specification of vc7.root in the properties file to specialize it for VS.NET 2003 and also updated the comment.
