compiling MESA-Motif widget app....undefined reference to `glwM2DrawingAreaWidgetClas
 

Hi,

I'm attempting to compile a MESA-Motif-Glut app on EL5. When this code is compiled, ld returns:

oddgui.c:5474: undefined reference to `glwM2DrawingAreaWidgetClass'

glwM2DrawingAreaWidgetClass is not referenced in the code:

XtCreateWidget("OGLMwidget", glwMDrawingAreaWidgetClass, frame3, al, ac);

It appears that GL/GLwDrawA.h is making the substitution:

#if XmVERSION == 2
/*
# define _GLwMDrawingAreaClassRec _GLwM2DrawingAreaClassRec
# define _GLwMDrawingAreaRec _GLwM2DrawingAreaRec
*/
# define glwMDrawingAreaWidgetClass glwM2DrawingAreaWidgetClass
# define glwMDrawingAreaClassRec glwM2DrawingAreaClassRec
# define GLwCreateMDrawingArea GLwCreateM2DrawingArea
#else
#error "Sorry, unknown Motif version."
#endif /* XmVERSION */

Yet both glwMDrawingAreaWidgetClass and glwM2DrawingAreaWidgetClass are in libGLw.so.1.0.0

I suspect that there's a problem in GLwDrawA because I don't see this problem under Solaris or Mac OSX.

The relevant packages are:

mesa-libGL-devel.i386 6.5.1-7.8.el5
mesa-libGLU-devel.i386 6.5.1-7.8.el5
mesa-libGLw-devel.i386 6.5.1-7.8.el5
openmotif-devel.i386 2.3.1-2.el5_4.1
freeglut-devel.i386 2.4.0-7.1.el5

Thanks, Jeff
