c++boost

silence -Wparentheses-equality error

Im building som software using boost 1.48 on osx 10.8 with gcc version 4.2.1 and i have started getting -Wparentheses-equality warnings for some of the boost source.

  equality comparison with extraneous parentheses
  [-Werror,-Wparentheses-equality]
        else if((state->type == syntax_element_long_set_rep))

I would change the code but i dont want to tinker with the library, how would i silence the warning and make the compiler continue?

Solution

  • From the GCC manual:

    Most of these have both positive and negative forms; the negative form of -ffoo would be -fno-foo.

    Try -Wno-parentheses-equality.
