#50304: libcxx @3.7.0 +universal compile error on MacOS 10.6.8 - build failure ---------------------------+-------------------------------- Reporter: cf-macports@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Keywords: | Port: libcxx ---------------------------+-------------------------------- Trying to build libcxx @3.7.0 with mp-clang 3.8 on MacOS 10.6.8 and Xcode Version 3.2.6 (1761). I run into the following compilation error: {{{ ---> Building libcxx + for FILE in '../src/*.cpp' + /opt/local/bin/clang++-mp-3.8 -c -g -Os -arch x86_64 -arch i386 -nostdinc++ -std=c++11 -U__STRICT_ANSI__ -I../include ../src/algorithm.cpp In file included from ../src/algorithm.cpp:11: lofwyr:files chris$ m ../include/random:1645: ../include/string:1938:44: error: 'basic_string<_CharT, _Traits, _Allocator>' is missing exception specification 'noexcept(is_nothrow_copy_constructible<allocator_type>::value)' basic_string<_CharT, _Traits, _Allocator>::basic_string(const allocator_type& __a) ^ ../include/string:1326:40: note: previous declaration is here _LIBCPP_INLINE_VISIBILITY explicit basic_string(const allocator_type& __a) ^ 1 error generated.

Adding the declaration fixes the compilation issue and the port builds correctly. I attached diff files of the changes I made. -- Ticket URL: <https://trac.macports.org/ticket/50304> MacPorts <https://www.macports.org/> Ports system for OS X
