This has nothing to do with Linux, so I've reported it to be moved. In future, please make sure you post in the right forum.

Looks like you need to specify a location for the includes. This is done using g++'s -I option. Also, FWIW, if you're trying to build an executable file, you won't want to use the -c option. This compiles but does not link libraries, so you won't get a complete executable.

Moved: This thread is more suitable in the General forum and has been moved accordingly to help your thread/question get the exposure it deserves.
