Re: gcc won't compile hello world
Pretty sure you made the same mistake as I did earlier today. Run g++ instead and it all will work much better I hope

Re: gcc won't compile hello world
well, the compiler output would have been much more useful than an strace. The gnu compilers are used by millions of people - I'm pretty sure someone would have noticed if it didn't compile c++ programs. Following that logic, it's most likely a program error.
Also, like biio said, use g++ for c++ apps, instead of gcc - that'll probably fix your issue because it compiles fine here:
g++ hello.cpp -o helloOffline

Re: gcc won't compile hello world
Like previous people said, gcc is a C compiler, and you are obviously using C++ (C does not have namespaces, C does not have cout and the << stream operator).

this is where i should really be coming up with my daily WTF?

Re: gcc won't compile hello world
for the record... with a file of "hello.cpp", running "make hello" will call the correct compiler

Re: gcc won't compile hello world
Don't feel too bad, I did the same thing when I first started using Linux.
