All Rights Reserved. Thank you Neill What are the compilation and linking commands you do to produce vclient? UNIX is a registered trademark of The Open Group. You can see that -lcfitsio -lm comes from line 301 in the makefile, how can I set it so that it comes at the end of the gcc commands?

Now, I have made the XPM_lib.h and XPM_lib.c files and also my test.c file.

The compiler will spit out object files that will later be linked into an executable.
