I try to ignore warnings coming from some 3rd party header files like this:
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunknown-pragmas"
#pragma GCC diagnostic ignored "-Wreorder"
#include <some_3rd_party_header.h>
#pragma GCC diagnostic pop
This approach seems to work in general, but not for the unknown pragma warnings (I still get them).
Why does it work for other warnings but not for this one? Can anyone confirm this behaviour?
I'm using g++ (version 4.7.1) with -Wall
and -std=c++0x
under Debian.
I've run into this annoyance, too. According to the GCC manpage -Wall
turns on -Wunknown-pragmas
for you, so just manually disable it using -Wno-unknown-pragmas
after -Wall
.
There is a GCC feature request to make this work using #pragma GCC diagnostic
:
