Checking Ansi-c++ conformity

[Ollej Reemt]

Hello,

I'm looking for a way to check/prove the ansi-c++ conformity of my
c++-code.
Does anyone know a tool for this problem? Or are there any
compiler-flags (for gcc, Visual C++ or any other compiler) to achieve this?
(Any not ansi-compliant statement should result in a warning or so)

Regards
ollej

Minimal g++ warning flags you should use for this are:
-ansi -pedantic -W -Wall

And for Visual C++ (at least 6.0), the /Za flag "disables extensions".

Or use a lint program, like the one from Gimpel : http://www.gimpel.com

Isn't -W the opposite of the rest?

No.

But the GCC manual says that it inhibits all warnings.

But the GCC manual says that it inhibits all warnings.

Check -Wextra. It says, among other things,

"(This option used to be called -W. The older name is still
supported, but the newer name is more descriptive.)"

I think you're confusing "-w" with "-W". They are different
options.
