[SOLVED] How do I use -Wall option on gcc/g++ and turn off the multi line comments warnings?

Issue

Like the title, how do I use -Wall option on gcc/g++ and turn off the multi-line comments warnings?

The comment looks like that:

// Comment starts here \
// and end here (the // at the beginning is not necessary)

Solution

You could use /* .. */ for the multiline comment.

    /* foo bar comment
       lala blah
    */

Edit:

I found a solution in another post here: How can I hide "defined but not used" warnings in GCC?

If you add the option -Wno-comment, the warning is gone.

    gcc -Wall -Wno-comment test.c -o test

It's also explained here: http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
