Unfortunately we could not test 1.30 extensively and thus found a problem with the current Boost sources just after a release.
When trying to compile the filesystem library with KAI C++ we encounter a problem in
boost/type_traits/is_base_and_derived.hpp
It seems that the workaround is needed also for KCC, since otherwise we get the error message
line 126: error: expression must have (pointer-to-) function type BOOST_STATIC_CONSTANT(bool, value =
Looking at the #if before this version I find:
&& !BOOST_WORKAROUND(__EDG_VERSION__, <= 238) && 0
// The EDG version number is a lower estimate.
// It is not currently known which EDG version
// exactly fixes the problem.
KAI C++ version 4.0f has an __EDG_VERSION__ of 243 but this still fails. Can 238 here be changed at least to 243?
Best regards,
