Dear developers: I encountered an error when compiling software that uses boost. I'm using boost_1.72.0, and the compiler I used is intel mpiicpc (ICC) 16.0.3 20160415 Below is the error message: [ 1%] Building CXX object src/core/CMakeFiles/EspressoCore.dir/accumulators.cpp.o In file included from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/utility.hpp(22), from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/range/size.hpp(25), from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/range/functions.hpp(20), from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/range/iterator_range_core.hpp(38), from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/range/iterator_range.hpp(13), from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/range/detail/range_return.hpp(14), from /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/range/algorithm/remove_if.hpp(16), from /THL7/home/hugq/xikai_jiang/Softwares/espresso-4.1.2/src/core/accumulators.cpp(21): /THL7/home/hugq/xikai_jiang/Softwares/boost_1_72_0/build/include/boost/core/noncopyable.hpp(42): error: defaulted default constructor cannot be constexpr because the corresponding implicitly declared default constructor would not be constexpr BOOST_CONSTEXPR noncopyable() = default; ^ compilation aborted for /THL7/home/hugq/xikai_jiang/Softwares/espresso-4.1.2/src/core/accumulators.cpp (code 2) make[2]: *** [src/core/CMakeFiles/EspressoCore.dir/accumulators.cpp.o] Error 2 make[1]: *** [src/core/CMakeFiles/EspressoCore.dir/all] Error 2 make: *** [all] Error 2 Let me know if you need further information to diagnose the issue.

Boost 1.70 Thread library and Sun Studio Pro 12.4
by mik 12 Dec '19

12 Dec '19

Hi, just to signal an issue that I encounter with the boost (1.70) thread library compiling my library. I got this linking problem: Undefined first referenced symbol in file void boost::detail::set_tss_data(const void*,void(*)(void(*)(void*),void*),void(*)(void*),void*,bool) CMakeFiles/basic.dir/containers/MemoryPool.cpp.o void*boost::detail::get_tss_data(const void*) CMakeFiles/basic.dir/containers/MemoryPool.cpp.o So I investigated and I found that was missing the export keyword for Sun Solaris. I modified the file boost/thread/detail/config.hpp:498 in this way #elif (__GNUC__ == 4 && __GNUC_MINOR__ >= 1) || (__GNUC__ > 4) || (__SUNPRO_CC) and I solved it. I hope this could be useful for someone. Regards, Mirko

coroutine/asymmetric_coroutine.hpp no member named 'begin' in namespace boost
by Martijn Otto 12 Dec '19

12 Dec '19

After upgrading from boost 1.71 to 1.72 the following simple example now leads to a compilation error: #include <boost/asio/spawn.hpp> int main() { return 0; } The compilation errors point to a missing boost::begin and boost::end functions: /usr/local/include/boost/coroutine/asymmetric_coroutine.hpp:2364:10: error: no member named 'begin' in namespace 'boost'; did you mean simply 'begin'? { return boost::begin( c); } It goes on for a while, but I think the problem is clear. The source of this problem seems that between 1.71 and 1.72 in boost/coroutine/asymmetric_coroutine.hpp the include of boost/range.hpp was removed, which leads to these functions being undefined. To me it looks like a clear bug, but the fact that this include was removed points to some deliberate action. Am I missing something?

[release] 1.73.0 open for merging
by Marshall Clow 11 Dec '19

11 Dec '19

The master branch is open for merging all stable changes from develop, including bug fixes and major upgrades to existing libraries. Breaking changes should be coordinated via the mailing list with the developers of the other libraries affected. New libraries may be added, but require permission of a release manager. In other words, merging does not require permission from a release manager, except for new libraries.

Boost 1.70 - Test library error on Sun Solaris Studio 12.3
by mik 11 Dec '19

11 Dec '19

Hi, I'm triying to compile the boost 1.70 on Sun solaris using the version 12.3, but I got an annoying error on the test library: "./boost/test/unit_test_log_formatter.hpp", line 39: Error: Identifier expected instead of "__global". For what I can understand it seems that compiler doesn't recognize the keyword __global. Below, there's the command line that I've used: ./b2 toolset=sun variant=debug address-model=64 threading=multi link=shared runtime-link=shared --with-test Do you have any suggestions? Thanks, Mirko
