So using gcc on a C++ source file will call the C++ compiler but fail to link in the C++ standard library unless you explicitly tell gcc to do so. Which is why using gcc on C++ source files can lead to linker errors. (And yes, I recognize that Martin knows the difference and was simplifying to make it easier for new users.) Best regards, Tom
