[contract] _NOEXCEPT errors in <ostream> for Clang 5.0 C++1z on Teeks Linux
Hello all, Most of Boost.Contract regression test fail for toolset clang-gnu-linux-5.0~c++1z~lc on platform teeks99-02-dc5-1z-lc-Docker-64on64 because of the following error on #include <ostream> done by Boost.Range (and sometimes by Boost.IOStreams): "clang++-5.0" -c -x c++ -Wno-c99-extensions -std=c++1z -stdlib=libc++ -isystem/usr/include/libcxxabi -O0 -g -fno-inline -Wall -g -fPIC -m64 -DBOOST_ALL_NO_LIB=1 -DBOOST_CONTRACT_DISABLE_THREADS -DBOOST_CONTRACT_DYN_LINK -DBOOST_SYSTEM_DYN_LINK=1 -I".." -I"../libs/contract/test/function" -o "/var/boost/run/results/boost/bin.v2/libs/contract/test/function-smoke.test/clang-gnu-linux-5.0~c++1z~lc/debug/threadapi-pthread/function/smoke.o" "../libs/contract/test/function/smoke.cpp" In file included from ../libs/contract/test/function/smoke.cpp:9: In file included from ../libs/contract/test/function/../detail/oteststream.hpp:10: In file included from ../boost/iostreams/tee.hpp:18: In file included from ../boost/iostreams/detail/adapter/device_adapter.hpp:22: In file included from ../boost/iostreams/detail/call_traits.hpp:15: In file included from ../boost/iostreams/traits.hpp:38: In file included from ../boost/range/iterator_range.hpp:14: In file included from ../boost/range/iterator_range_io.hpp:32: In file included from /usr/include/c++/v1/ostream:138: In file included from /usr/include/c++/v1/ios:216: In file included from /usr/include/c++/v1/__locale:15: /usr/include/c++/v1/string:1942:14: error: expected ';' at end of declaration _NOEXCEPT ^ /usr/include/c++/v1/string:1947:9: error: expected unqualified-id _NOEXCEPT ^ /usr/include/c++/v1/__config:368:21: note: expanded from macro '_NOEXCEPT' # define _NOEXCEPT noexcept ^ 2 errors generated. Of course, Boost.Range and Boost.IOStreams show the same error on this toolset/platform independently of Boost.Contract. Any idea what the issue might be? Thanks, --Lorenzo

Looks like a libc++ bug, like a missing semicolon.

Looks like this was already marked as a Clang/Libc++ bug by Boost.RegEx: https://svn.boost.org/trac10/ticket/7872 I'll go with that conclusion. Thanks. --Lorenzo

This was marked (by me!) as a clang bug - that was fixed in clang trunk in January 2013. I find it hard to believe that you're running a clang built from those sources. -- Marshall

Or rather, from a set of sources from before then. -- Marshall

So I looked into this a bit more this weekend. The teeks99-[d|m]c5-1z-lc-Docker-64on64 build was using ubuntu's standard version of libc++, 3.7.0. In theory, that should work with any compiler version, including clang 5.0....but looking at the large number of compilation errors against that specific runner (the identical clang build that uses libstdc++, the default, instead has none of these issues), something is obviously not working correctly. So on friday I updated that docker image[1] to use a ubuntu ppa with a supposedly updated version (V5.0.0, from 2017-09-11) of libc++[2]. However in the subsequent run with that version, I'm still seeing the same issue. I'm guessing it might be some issue with my config? Is there some minimal source file that produces the same error I can try running to investigate further? If anyone wants to look for themselves, you can pull my docker image: docker pull teeks99/boost-cpp-docker:clang-5 There's a boost build user-config.jam file[3] in the root of that image, the toolset that build is using is "clang-5.0~c++1z~lc".

I can't be sure but from what I saw in the error message it seems the error is raised as soon as <ostream> is included so I'd expect the following to reproduce the error already: #include <ostream> int main() { return 0; } --Lorenzo

Something is wrong with that libc++ install as clang is 5.0, but <__config> line 368 only has this content at release_37: https://github.com/llvm-mirror/libcxx/blob/release_37/include/__config#L368 and I can't a version of <string> that corresponds to the above lines 1942 and 1947.

I think I need more context for this. Looking at the 5.0 libc++ sources, I see this: 1490: template <class _CharT, class _Traits, class _Allocator> 1491: inline _LIBCPP_INLINE_VISIBILITY 1492: basic_string<_CharT, _Traits, _Allocator>::basic_string() 1493: _NOEXCEPT_(is_nothrow_default_constructible<allocator_type>::value) 1494: { 1495: #if _LIBCPP_DEBUG_LEVEL >= 2 1496: __get_db()->__insert_c(this); 1497: #endif 1498: __zero(); 1499: } 1500: 1501: template <class _CharT, class _Traits, class _Allocator> 1502: inline _LIBCPP_INLINE_VISIBILITY 1503: basic_string<_CharT, _Traits, _Allocator>::basic_string(const allocator_type& __a) 1504: #if _LIBCPP_STD_VER <= 14 1505: _NOEXCEPT_(is_nothrow_copy_constructible<allocator_type>::value) 1506: #else 1507: _NOEXCEPT 1508: #endif Which doesn't match what you're reporting. -- Marshall
