Hi. I have an application that requires a few source files and a Makefile and it uses cairo.h. It was running a few months ago before I got a new hard drive and installed new Linux versions. I have Ubuntu as shown below. How can I compile my program? The command "make promog" which I created with the Makefile produces the errors in the attached file 'err4' root@kayve-Ubuntu11:~# gcc -v Using built-in specs.
