[Plib-users] Linking or compaling problem.

[Francisco C. <fra...@gm...>]

Hi everybody. I'm new to the list and I wrote here because I need
help. I read the list archives but I couldn' t find the solution, only
a few tips but they thosen' t are enough for me...
The problem is this, I dowload the package of plib and I compiled it
with cygwin and Dev-cpp (mingw). The compilation runs fine I think, I
get the lib*.a files. Then I think the problem is with the linker...
I get a simple piece of code that uses SDL and openGL and compile and
run fine, then I modified this code with two or three lines to get
plib in my program, but the the program don't finish the compiling
anymore. It's seems that they don't recognize the openGL functions
gl*(*).
I think maybe is the order of the parameters passed to the linker (I
read a problem like that in the archives) but my experience with this
enviroment is still too little...
Here are the makefile the Dev-cpp automatically generate for the project:

# Project: SDL-GL_01
# Makefile created by Dev-C++ 4.9.9.0

And the errors that the linker shots me are like this:

../../lib/plib/libplibpu.a(pu.o): In function `Z16glIsValidContextv':
C:/Archivos de programa/Dev-Cpp/include/plib-1.8.4/src/pui/pu.cxx:105:
undefined reference to `wglGetCurrentContext@0'

../../lib/plib/libplibpu.a(pu.o): In function `Z12puDrawCursorii':
C:/Archivos de programa/Dev-Cpp/include/plib-1.8.4/src/pui/pu.cxx:137:
undefined reference to `glColor4fv@4'

C:/Archivos de programa/Dev-Cpp/include/plib-1.8.4/src/pui/pu.cxx:139:
undefined reference to `glBegin@4'
C:/Archivos de programa/Dev-Cpp/include/plib-1.8.4/src/pui/pu.cxx:140:
undefined reference to `glVertex2i@8'

etc, etc...

In the code I already do this:

#define _WIN32_WINNT 0x0500    =20
#define WINVER 0x0500
#define WIN32_LEAN_AND_MEAN
#define NOGDI

#include <windows.h>

#include <gl/gl.h>
#include <SDL/SDL.h>
#define PU_USE_SDL  1
#include <plib/pu.h>

In this order...
Well, this is a picture of the problem. Like I'd say I have little
experience yet, so I couldn't find a solution to this problem. If
someone can help me I really appreciate the effort...
Thanks a lot...
