View Full Version : default include directories /usr/local/include

September 24th, 2005, 04:28 AM
General question: How do I add a path/directory to the default path that gcc/ld looks at?

My problem:
I'm observing that /usr/local/include is not searched by default when gcc/g++ is run. I'm trying to include a header file from the Boost libraries that I've install there.
[found at: /usr/local/include/boost/... ] I'm trying to include with #include <boost/headerfile.h>

EDIT: Ok, after a starting my laptop up again this morning its finding the my boost libraries... I would still be curious to know if its possible to add a path to the default search directory.

You can use the 'I' flag in gcc -

gcc -I /usr/local/include/ myprogram.c
