Some work I'm doing for a client requires me to build using a very old version of gcc on Red Hat Enterprise. We recently shifted from 4.x to 5.3 and I'm hitting some compile errors when I try to build simple example:
#include <iostream>
int main()
{
std::cout << "Hello World" << std::endl;
return 0;
}
I get the following:
bash-3.2$ g++ -o hello hello.cpp

__LOCK_INITIALIZER
is a pthreads macro, but clearly I'm not using it directly here. Has anyone seen this kind of problem before or can offer any possible suggestions as tyo why this is happening?
