websocketpp库中的错误和Windows中的提升Visual Studio 2015

Question

我想从开发人员github编译这个简单的例子https://github.com/zaphoyd/websocketpp/blob/master/examples/echo_server/echo_server.cpp，但我得到的代码之外的奇怪的错误。

我也曾尝试开启/杂志选项，如图这篇文章：VC++ 2012 and Boost incompatibility - `throw()` specifications in library headers但它抛出不同的错误，称“线程支持unavaliable：它已与BOOST_DISABLE_THREADS被明确禁用”

是否有人知道如何解决这个问题？ 谢谢！

的错误： 我使用Visual Studio 2015年在Windows10 64， C:\websocketpp\websocketpp/transport/base/connection.hpp(187): error C2694: 'const char *websocketpp::transport::error::category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/transport/base/connection.hpp(187): note: see declaration of 'websocketpp::transport::error::category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\websocketpp\websocketpp/transport/iostream/base.hpp(89): error C2694: 'const char *websocketpp::transport::iostream::error::category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/transport/iostream/base.hpp(89): note: see declaration of 'websocketpp::transport::iostream::error::category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\websocketpp\websocketpp/error.hpp(151): error C2694: 'const char *websocketpp::error::category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/error.hpp(151): note: see declaration of 'websocketpp::error::category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\websocketpp\websocketpp/frame.hpp(831): warning C4267: '=': conversion from 'size_t' to 'uint32_t', possible loss of data 1>C:\websocketpp\websocketpp/extensions/extension.hpp(65): error C2694: 'const char *websocketpp::extensions::error::category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/extensions/extension.hpp(65): note: see declaration of 'websocketpp::extensions::error::category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\local\boost_1_59_0\boost/asio/detail/config.hpp(227): warning C4005: 'BOOST_ASIO_ERROR_CATEGORY_NOEXCEPT': macro redefinition 1> C:\local\boost_1_59_0\boost/asio/detail/config.hpp(213): note: see previous definition of 'BOOST_ASIO_ERROR_CATEGORY_NOEXCEPT' 1>C:\websocketpp\websocketpp/transport/asio/base.hpp(189): error C2694: 'const char *websocketpp::transport::asio::error::category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/transport/asio/base.hpp(189): note: see declaration of 'websocketpp::transport::asio::error::category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\websocketpp\websocketpp/transport/asio/security/base.hpp(109): error C2694: 'const char *websocketpp::transport::asio::socket::socket_category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/transport/asio/security/base.hpp(109): note: see declaration of 'websocketpp::transport::asio::socket::socket_category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\websocketpp\websocketpp/processors/base.hpp(165): error C2694: 'const char *websocketpp::processor::error::processor_category::name(void) const': overriding virtual function has less restrictive exception specification than base class virtual member function 'const char *std::error_category::name(void) noexcept const' 1> C:\websocketpp\websocketpp/processors/base.hpp(165): note: see declaration of 'websocketpp::processor::error::processor_category::name' 1> C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\system_error(167): note: see declaration of 'std::error_category::name' 1>C:\websocketpp\websocketpp/common/md5.hpp(367): warning C4267: '+=': conversion from 'size_t' to 'websocketpp::md5::md5_word_t', possible loss of data 1>C:\websocketpp\websocketpp/sha1/sha1.hpp(176): warning C4267: '=': conversion from 'size_t' to 'unsigned int', possible loss of data ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Answer 1

定义_WEBSOCKETPP_NOEXCEPT_和_WEBSOCKETPP_CPP11_CHRONO_的伎俩对我来说:) https://github.com/zaphoyd/websocketpp/issues/437
