Compiling C and C++ files together using GCC

Question

I'm trying to compile C and C++ sources together using GCC.

gcc -std=c++0x test.cpp -std=c99 test.c -lstdc++

Now, this works fine, except that I get two warnings.

cc1plus: warning: command line option "-std=c99" is valid for C/ObjC but not for C++ cc1: warning: command line option "-std=c++0x" is valid for C++/ObjC++ but not for C 

Therefore I can't use -Werror with this setup. Can these warnings be suppressed somehow?

Answer 1

if anyone else is wondering the best way to do this in Android, it's this:

LOCAL_CFLAGS := -Werror LOCAL_CONLYFLAGS := -std=gnu99 LOCAL_CPPFLAGS := -std=c++0x 

Answer 2

Compile the files separately, link with g++

gcc -c -std=c99 -o file1.o file1.c g++ -c -std=c++0x -o file2.o file2.cpp g++ -o myapp file1.o file2.o
