How to build WarpMesaGL samples ?
--------------------------------------------------------
1. unzip examples
2. ren \TOOLKIT\H\gl \TOOLKIT\H\gl_old
3. run \Samples\makeAll.cmd
4. in case of problems look run single \Samples\makeOne.cmd SampleDirName

How to convert any OpenGL samples to WarpMesaGL samples ?
--------------------------------------------
Example: source file -  MesaCVS\samples\line.c

build Warp OpenGL sample:
(a)  copy line.c and tkmap.c to selected directory,
     copy MAIN.C and basis.h from \Samples\OGL_SAMPLES
to the same directory:

Directory of G:\MESA\OS2_port\Samples\LINE

27.02.00  14:12      <DIR>             0  .
27.02.00  14:12      <DIR>             0  ..
13.02.00   2:33        391             0  basis.h
19.08.99   3:55       4266             0  line.c
13.02.00   2:32       1473             0  MAIN.C
19.08.99   3:55       1212             0  tkmap.c
27.02.00  16:43         77             0  makeitOGL.cmd
27.02.00  16:13         30             0  runit32.cmd

(b)
  change in line.c name of main to mainint:

//int main(int argc, char **argv)
int maininit(int argc, char** argv)
(b1)
change includes
#include <GL/gl.h>
#include <GL/glu.h>
to
#include "basis.h"

(b2) delete, if there is
#include "aux.h"
and change all aux* functions to its glut analogs

(c1)  to compile with from command line (makeitOGL.cmd): 
icc -Ss -Ms line.c MAIN.C   -B" /st:1000000 /nop OPENGL.lib GLUT.lib" 

(c2) 
  to compile from VAC++ 3 WorkFrame rename tkmap.c to tkmap.h. and change
in line.c  #include "tkmap.c" to  #include "tkmap.c"
Deselect "Use Optlink linkage" in compiler options, set stack size to 
1000000 and add OPENGL.lib GLUT.lib libraries

(c3) To run line.exe at some videodrivers & videmodes with 32bits per pixel
make runit32.cmd:

SET OGL_BIT_COUNT=32
line.exe
=====================================

build WarpMesaGL sample:
(a1) copy line.c and tkmap.c to selected directory,
(a2) copy MAIN.C,basis.h,GL_TEST.H,GL_TEST.RC,MesaGL.ico from \Samples 
     (not from \Samples\OGL_SAMPLES !) to the same directory;
(a3) copy MesaGL2.LIB and MesaGLUT.LIB to the same directory, or somewhere
     at LIB  enviroment path 
(a4) copy MESA\OS2_port\GL directory to MESA\OS2_port\Samples\LINE or
     adjust path to GL in basis.h
(a5) copy MesaGL2.DLL, MesaGLUT.dll to the same directory if you 
     have "." in your LIBPATH, or copy somewhere at LIBPATH
  
You will have something like that:
