Sir, I'm trying to compile my C source code using gcc, but it seems that it can't locate the required header files. I'm using the -I option to specify the directory where the header files are located, but it still cannot find them. Here's the command line that I'm using: gcc -I/usr/openwin/share/include/Xol -L/usr/lib -lX11 -v -o program program.c Inside my code there's a reference to the files OblongButt.h, Button.h, and Openlook.h, all of which are in the /usr/openwin/share/include/Xol directory. For some reason, I always get these errors: s_button.c:2: Openlook.h: No such file or directory In file included from s_button.c:3: /usr/openwin/share/include/Xol/OblongButt.h:40: Xol/Button.h: No such file or directory Any help would be much appreciated.
