problem on programming in redhat9

Hi, I am a beginning of OpenGL programmer.
My os is redhat9.
Here is a test code with compile errer like the
following:

firstMesa.c: In function Key': firstMesa.c:104:tk_ESCAPE’ undeclared (first use in this function)
firstMesa.c:104: (Each undeclared identifier is reported only once
firstMesa.c:104: for each function it appears in.)

The compiler is looking for the “tk” library files.

I also use RH 9.0 but I have not used this library, but it looks like your missing a include file that defines the tk routines, I did not see any #include<tk??.h>. Check and see if there is a include file for the tk stuff.

Thank you very much.
In fact, the coding should include a “gltk.h” file, but redhat9 doesn’t have this file.

I wonder that there is another way to
make the code work.

There are a couple of options.

Get the TK library for RedHat. I’m not familiar with this library either, but I’m sure it’s easily obtainable.
Convert the TK code over to use something like glut, SDL, FLFW, glx, etc…

The tk functions look very close to functions found in GLUT, the only problem there is a bug in the glut shipped with RH 9.0 and you have to download a version earlier then 9.0 for it to compile.
