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 -Xlinker -v :

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

使用 -L 标志，您可以向库路径添加其他路径。

Answer 3

its, capital I (i), not capital L. Example:

clang -fsanitize=unsigned-integer-overflow,signed-integer-overflow,shift,pointer-overflow -Wall -Wno-format-extra-args -g utilities.cpp -I/Users/myName/Git/myProj/src/libs "$@" &&./a.out
