# GCC*-Compatible Warning Options

This content is specific to C++; it does not apply to DPC++.

The Intel® oneAPI DPC++/C++ Compiler recognizes many GCC*-compatible warning options, but we do not document all of them.

In general, if a GCC-compatible option is accepted by the compiler, but not documented, the implementation of the option is the same as described in the GCC documentation.

To find the GCC documentation about GCC warning options, you can do any of the following:

- Check the GCC website (http://gcc.gnu.org/onlinedocs/gcc/)
- On Linux*, enter the command `man gcc`
- Search the web for "gcc warning options"
