Hi, A few of you have been trying to help me get going with compiling C++ code, but so far there's been no joy. The messages I'm getting are scrolling off the screen, but quite a few of them refer to: /usr/include/c++/3.2.3/i486-slackware-linux/bits/gthr-default.h Is there something that needs to be done to gcc before it becomes fully operational? Here's a copy of the code I last tried to compile: #include <iostream> using namespace std; int main() { cout << "Hello World!\n"; return 0; } Also, I was informed by a few of you that the modern C++ uses "iostream" with a "using namespace std;" instead of the "iostream.h" for the include. Does this mean that gcc is not backward compatible and will not compile older source code without modifications? Thanks -- Rob
