Re: [Plib-users] Errors building plib1.8.5

[Stuart M. <stu...@bl...>]

Hi,

   I'm afraid I'm not up on specifics as in how to fix this, but I can 
explain the process and hopefully that might help you track down the 
problem.

What the configure script is doing is generating test code which it 
compiles to see if it can find various libraries that are needed.So for 
example to see if ti can find the OpenGL library it generates code which 
calls glNewList (a function that must be in the library). It compiles 
and links that code and if works then it found the library.

So the /usr/include/GL won't afect this since it's about libraries, not 
include files. You need to find the location of libraries and ensure the 
-L compiler flag sets the path to search for those libraries e.g. if 
they are in /usr/local/lib then you need a -L /usr/local/lib so that 
-lMesaGL flag will find the /usr/local/lib/libMesa.sl library (name 
probably is different, like I said I don't know much about specifics on 
different machines).

Hopefully that is some help.

   Cheers,

Stuart.
