Confusing error message for c++ sources

[Tero Karvinen]

When trying to compile C++ files with 'gcc', a confusing screenfull of weird error messages is given. Instead, it should say something like "To compile C++ files, use g++. For example: 'g++ hello.cc'.

To reproduce:
1) $ cat hello.cc
#include <iostream>
int main(int argc, char *argv[])
{
        std::cout << "Hello C++ world!" << std::endl;
        return 0;
}
2) $ gcc hello.cc
/tmp/ccI0YbBc.o: In function `main':
[..]
std::operator<< <std::char_traits<char> >(std::basic_ostream<char, [..]
collect2: ld returned 1 exit status

note, that the files is correctly compiled; the linking fails. either you add -lstdc++, or just call g++.

[Tero Karvinen (karvinen+launchpad)]

You said it: "just call g++". Wouldn't it be nice if gcc could say this to users too?

The last line of the error message could be:

 Did you mean: g++ [file.cc]
