Compilation Error

[mistkhan]

Hi All

I have found a sample application to call Tk routines from C. However during the compilation, I am getting the following error. I am having a doubt, whether I am including the correct library.

It might be a silly error , please help in solving this error.

Thanking you in advance
Regards
Aman
