How to check programmatically that source compiles?

Question

There is some string with code:

std::string code = "int main(){return 0;}"

What tool can I use to check whether this is valid C++ code? Something similar to

checker.checkCPPcode(code) which returns bool

would be nice.

Answer 1

You can paste the content of the string in a newly created cpp file and run g++ or whatever compiler you can use on it and check the compiler's output.

Answer 2

A C++ compiler like g++ will do the job. Write the string into a temporary file, run g++ -fsyntax-only on the file, and act on the return value.
