I've discovered that the constant glwDrawingAreaWidgetClass is set to
0. It's supposed to be defined as:
WidgetClass glwDrawingAreaWidgetClass=(WidgetClass)&glwDrawingAreaClassRec;
Can I ask you to please provide some more details as to how you made
this discovery?
If you do this:
$ cat glw-test.c
#include <Xm/Xm.h>
#include <GL/GLwDrawA.h>
#include <stdio.h>
int main()
{
printf("glwDrawingAreaWidgetClass %p", glwDrawingAreaWidgetClass);
}
then you could reach that conclusion:
$ gcc glw-test.c ; ./a
glwDrawingAreaWidgetClass 0x0
but this isn't testing correctly as glwDrawingAreaWidgetClass isn't
marked as extern in GLwDrawA.h
$ cat glw-test.c
#include <Xm/Xm.h>
#include <stdio.h>
extern WidgetClass glwDrawingAreaWidgetClass;
int main()
{
printf("glwDrawingAreaWidgetClass %p", glwDrawingAreaWidgetClass);
}
$ gcc glw-test.c -lGLw ; ./a
glwDrawingAreaWidgetClass 0x5bd8e3640
Is it broken?
I don't know.
