Helpful hint: a really easy way to do this on SGI's is to

    > setenv GLERRORABORT anything

(or the equivalent way to set an environment varible in non-csh
shells).

Then any time a GL error occurs, your program will abort(), and you can
use a debugger to get a stack trace.

Note, it is a terrible idea to use this in a production environment!
But as a diagnostic tool it's great.

    As first steps:

  - Are you sure that you're using a GLX visual which supports stencil
    buffers on the O2?

  - Have you checked for any OpenGL errors generated during execution of
    the program?

Thanks for advices

I am afraid this command changes the environment
When I finish to check this command, how should i set the prebious
environment ?
like >setenv ???????

I don't know the wotd "GLX visual", i know GL for my programing.
How will i know I will be using it in my program.
The message of the program said "STENCIL available" at
getgdesc(GD_BITS_STENCIL).
Thanks again in advance
Nagata shojiro

Very much thanks
I set "setenv GLERRORABORT anthing"
But no error message and also there is no "core" file as the program was
running without breaking.

thanks for other next advices

How do i know if I am using a GLX visual ?

I got the information and this does not support stencil buffers on the O2 as
the last text shows

How can i fix it ?
thanks in advance very much

Here is my program using stencil() runing on Indigo2,Ocatne, but not on O2.
Appreciate very much Any suggestions to fix it.

----from here
void stencilmask(int eyer){
   if(eyer==0) stencil(TRUE,0x1, SF_EQUAL,   0x1, ST_KEEP, ST_KEEP,
ST_KEEP);
   else if(eyer==1) stencil(TRUE,0x1, SF_NOTEQUAL,0x1, ST_KEEP, ST_KEEP,
ST_KEEP);
}
void
cilpatdraw(){  
static   int gid2, j;
 static   long   vert1[2],vert2[2];
 static   long   xscrmax,yscrmax;

     prefposition(0.0, xscrmax, 0.0, yscrmax);
     gid2= winopen(" stencil pattern");
     ortho2( 0.0, xscrmax, 0.0, yscrmax);
     stensize(1);  sclear(0x00);     subpixel(1);
     stencil(TRUE, 1, SF_ALWAYS, 0x1, ST_REPLACE, ST_REPLACE, ST_REPLACE);
     zfunction(ZF_NEVER); cpack(0x00); clear();
     vert1[0]= 0.0;  vert2[0]= xscrmax;
     for(j= 0; j<yscrmax; j+=2){
      vert1[1]= vert2[1]= j;
      bgnline(); v2i(vert1); v2i(vert2); endline();
     }
    winclose(gid2);
