Overture SW compilation

[Padiyath Sreekumaran]

  Hello,
  Iam trying to install a SW on a RedHat OS V3 machine. This SW
  requires OpenGL, Motif etc. programs. Iam getting an error
  when I execute the make file of the Program Overture. 

osRender.C:204:34: GL/../../src/context.h: No such file or directory
<-----------------------
osRender.C:219: 'GLcontext' is used as a type, but is not defined as a type.
osRender.C:220: syntax error before `*' token

osRender.C:333: syntax error before `)' token
make[1]: *** [osRender.o] Error 1
make: *** [all] Error 2

   Iam missing the header file context.h. From where I can get this?
   Any suggestions will be very much appreciated.

   Regards,
   Kumar
