How can I force gcc to compile a c/c++ program that has a c-style
extension w/o changing that extension??

Hi Justin,
For instance:
gcc -x c++ foo.whatever

Ok, that seemed to allow it to compile, but not to link. These are just
a sample of the errors I'm getting. Any clue??

Hi Justin,
It looks like your C++ file isn't C++ compliant.
Does it have...
#include <string>
using std::string;
...or...
#include <string>
using namespace std;
...near the top?

Yes, it indeed does have this.

Hi Justin,
If it's a C++ program, are you using 'g++' instead of 'gcc'?
The 'g++' one includes all the C++ related stuff for linking, whereas 'gcc' does not. If you wanted to use 'gcc' you have to include the C++ stuff explicitly.

Yeah, I think I'm being required to use gcc, not g++. What would I need
to explicitly include in order to use gcc?

Hi Justin,
That can vary depending on platform.
On my platform the g++...
g++ foo.cpp
...is equivalent to the gcc...
gcc -nostdlib -x c++ foo.cpp -lstdc++ -lm -lgcc_s -lgcc -lc -lgcc_s -lgcc crtend.o crtn.o
Likely, this will vary from platform to platform.

Justin,
You _may_ also get by simply by linking to the standard C++ library (that's where the symbols it was complaining about are defined): -lstdc++.
Thanks,
Lyle Taylor
