GCC has built in include directories for certain standard headers. I just need to know where this list is. My newly compiled gcc will not compile my little test C++ program because it cannot find standard headers. I think it fails because of some config options I used to make my file system more organized. I set the bindir and libdir, which I think might have screwed up the built-in include paths for some reason.

Program (dummy.c):

#include <iostream>
void main(){}

Command:

g++ dummy.c

Error:

dummy.c:1:20: fatal error: iostream: No such file or directory
