Add library search path to clang

Question

How can I add /usr/local/lib to my clang library search path?

This is what I see when I list my library search paths using clang -Xlin

Answer 1

Is it OK to add it as environment variable?

This should work:

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib

Notice, it's LIBRARY_PATH, not LD_LIBRARY_PATH.

On the other hand, if that doesn't work for you, you should compile with the flag:

-L/usr/local/lib

And that should be sufficient, too.

EDIT: Btw, I don't know why you're using back-slashes instead of slashes... that needs explanation. Use slashes always. Even on Windows.

Answer 2

With the -L flag you can add additional paths to your library path.
