boost::mpl/has_xxx.hpp gives several errors

[Ivo Raisr <ivosh@…>]

when using boost 1.47.0 with gcc 4.1.2 and -Wundef -Werror, it gives the following errors

boost/mpl/has_xxx.hpp:344:9: error: "BOOST_MPL_HAS_XXX_NO_EXPLICIT_TEST_FUNCTION" is not defined
boost/mpl/has_xxx.hpp:357:9: error: "BOOST_MPL_HAS_XXX_NO_WRAPPED_TYPES" is not defined
mpl/has_xxx.hpp:386:9: error: "BOOST_MPL_HAS_XXX_NO_EXPLICIT_TEST_FUNCTION" is not defined
boost/mpl/has_xxx.hpp:459:8: error: "BOOST_MPL_HAS_XXX_NEEDS_TEMPLATE_SFINAE" is not defined

This problem has been already addressed by bug report 4666, but apparently its part for MPL has been forgotten. Therefore I would like to resurrect this problem again.

Either the logic of defining these four #define's needs to be revisited in the header file, or their usage must be rewritten to check whether the #define is defined at all. For the latter case, I'm attaching a patch.

Should you need more information, just ping me. Ivo Raisr

Problem also exists for me on OS X Lion with GCC 4.2.1 and Boost 1.48.

The problem still exists on Win7 x64 with MSVC2010 and Boost 1.52. The patch works of course as it should.

The problem still exists on OS X 10.8.5 with Boost 1.55.0. Output of clang++ --version:
