In the software project I'm working on, we use certain 3rd party libraries which, sadly, produce annoying gcc warnings. We are striving to clean all code of warnings, and want to enable the treat-warnings-as-errors (-Werror) flag in GCC. Is there a way to make these 3rd party generated warnings, which we cannot fix, to disappear?

Use -isystem Example:

gcc -I./src/ -isystem /usr/include/boost/ -c file.c -o obj/file.o

With -isystem NO warning about boost :D
