Alexander, This version 3.1 of clang did not claim full C++11 support, neither does FreeBSD 9.X at this point. Full C++11 support is targeted at FreeBSD 10 according to the site below. > A key element in solving both problems was the installation of gcc47.

GCC 4.7 is not GCC 4.2, and GCC 4.7 or 4.8 do not claim full C++11 compliance either; additionally, GCC 4.7 and 4.8 label their C++11 support "experimental". > 1.. > Symptom: > > %> clang++ -std=c++11 -stdlib=libstdc++ refparms.c++ > initListTest.cpp:43:10: fatal error: 'initializer_list' file not > found > #include <initializer_list> You are mixing clang with the GNU libstdc++. libc++ ships with initializer_list, but on my upgraded-through-many-releases 9.1 amd64, this header does not get installed. See <https://wiki.freebsd.org/NewC%2B%2BStack>, apparently, you need to make system configuration changes and recompile parts of it.

See above.
