I am sure you have an answer by now but if not, here is a comment from 'Beginners 'c' ...

Standard header files (those supplied by your 'c' compiler vendor) are placed into '/usr/include' and in folders below that one. These are referenced in your 'c' program by placing '<>' around them. This means that <stdio.h> will be searched for in '/usr/include' Standard files in folders below '/usr/include' must include the path prefix. An example of this would be '<sys/ipc.h>'

Non-standard header files, those created by you or supplied by a third party, can be located just about anywhere. In your 'c' program, these are referred to with '&quot;&quot;' around them. Because they are not limited to where they are located, it is common practice to put the full pathname within the quotes ie, &quot;/usr/myfolder/myproject/myheader.h&quot;. The exception to this is if the header file is located in the same folder you are in when you start the compile.

Finally, 'Makefiles' and the 'c' compiler allow you to provide search paths (-I option) to any non-standard header file locations.
