Hi,

It seems that the checking to define BOOST_NO_CXX11_VARIADIC_TEMPLATES or not is slightly wrong when __GNUC__ > 4 (in this case __GNUC__ == 5)

This was tried fixed in [SVN r70019], but it looks like the fix was wrong for __GNUC__ > 4.

(git 050da29d47ce43b1dca6bed03d54c40d5e3d315e)

This is the current code:

// Variadic templates compiler: // http://www.generic-programming.org/~dgregor/cpp/variadic-templates.html # if defined(__VARIADIC_TEMPLATES) || (__GNUC__ > 4) || ((__GNUC__ == 4) && \ (__GNUC_MINOR__ >= 4) && defined(__GXX_EXPERIMENTAL_CXX0X__)) # define BOOST_HAS_VARIADIC_TMPL # else # define BOOST_NO_CXX11_VARIADIC_TEMPLATES # endif #endif

This is my proposed fix:

diff --git a/functional/boost/boost/config/compiler/gcc.hpp b/functional/boost/boost/config/compiler/gcc.hpp index ef6b07e..736e8ba 100644 --- a/functional/boost/boost/config/compiler/gcc.hpp +++ b/functional/boost/boost/config/compiler/gcc.hpp @@ -157,7 +157,7 @@

(I'll post a none-damaged diff if wanted.)
