Compile error in tests on Windows in MSVS 2019

[ales-kunst]

When I try to compile the tests in MSVS 2019 I get following compile-time errors:

Severity Code Description Project File Line Suppression State Error C2678 binary '==': no operator found which takes a left-hand operand of type 'const Executor' (or there is no acceptable conversion) with [ Executor=std::reference_wrapper<boost::asio::io_service> ] test_endpoint D:\programming\projects\cpp\3rdparty\boost_1_70_0\boost\asio\impl\executor.hpp 218 Error C2678 binary '==': no operator found which takes a left-hand operand of type 'const Executor' (or there is no acceptable conversion) with [ Executor=std::reference_wrapper<boost::asio::io_service> ] test_transport_asio_security D:\programming\projects\cpp\3rdparty\boost_1_70_0\boost\asio\impl\executor.hpp 218 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 319 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 402 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 427 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 448 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 468 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 493 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 526 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 564 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 574 Error C3861 'sleep': identifier not found test_transport D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\integration.cpp 604 Error C3861 'sleep': identifier not found test_transport_asio_timers D:\programming\projects\cpp\3rdparty\websocketpp\test\transport\asio\timers.cpp 188

Did I do anything wrong or do I need to add some preprocessor directives. All errors are connected somehow with boost libraries (or maybe I am wrong). I am using boost libraries 1.70.

[ales-kunst]

The first two problems I have solved with the solution (removing lib::ref) from issue #794. But the "sleep: identifier not found" I do not know which sleep should I take (from boost thread?).

二进制“==”: 没有找到接受“const Executor”类型的左操作数的运算符(或没有可接受的转换)

Hi, i have the same error as @ales-kunst related to boost. I have tried 1.70 to 1.72 boost libraries to built with vs2019 but unsuccesfully

boost\asio\impl\executor.hpp(218,1): error C2678: binary '==': no operator found which takes a left-hand operand of type 'const Executor' (or there is no acceptable conversion)

Is something i can do in websocketpp or boost?

我也遇到了同样的问题，在笔记本上报错，但是在台式机上是正常的，如何解决？
vs2019 16.5.0
boost 1.72

[huhuang03]

As #794, you can use boost 1.69..

[vkaragounis]

I have overcome this issue by downloading 1.72 boost and building myself with cmake (gui).
The folder lib32-msvc-14.2 created after building boost library contains the dlls that are compatible.
Project built with Visual Studio 2019 (v142) platform toolset.
As i can recall, i download develop branch

I think that my question is duplicate to issue #794 . Anyway I have used the following command lines to replace/remove some lines of code from certain files (look in the command line) to be able to compile the project:

sed -re '/#include ^<syslog.h^>/ d' ^
< %repo_location%\tmp\websocketpp\websocketpp\logger\syslog.hpp.orig > %repo_location%\tmp\websocketpp\websocketpp\logger\syslog.hpp

if not exist "%repo_location%\tmp\websocketpp\websocketpp\transport\asio\connection.hpp.orig" (
copy %repo_location%\tmp\websocketpp\websocketpp\transport\asio\connection.hpp %repo_location%\tmp\websocketpp\websocketpp\transport\asio\connection.hpp.orig
)
sed -e 's/lib::ref(*m_io_service)/*m_io_service/' ^
-e 's/lib::ref(*io_service)/*io_service/' ^
< %repo_location%\tmp\websocketpp\websocketpp\transport\asio\connection.hpp.orig > %repo_location%\tmp\websocketpp\websocketpp\transport\asio\connection.hpp

if not exist "%repo_location%\tmp\websocketpp\websocketpp\transport\asio\endpoint.hpp.orig" (
copy %repo_location%\tmp\websocketpp\websocketpp\transport\asio\endpoint.hpp %repo_location%\tmp\websocketpp\websocketpp\transport\asio\endpoint.hpp.orig
)
sed -e 's/lib::ref(*m_io_service)/*m_io_service/' ^
< %repo_location%\tmp\websocketpp\websocketpp\transport\asio\endpoint.hpp.orig > %repo_location%\tmp\websocketpp\websocketpp\transport\asio\endpoint.hpp

if not exist "%repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\none.hpp.orig" (
copy %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\none.hpp %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\none.hpp.orig
)
sed -e 's/lib::ref(*service)/*service/' ^
< %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\none.hpp.orig > %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\none.hpp

if not exist "%repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\tls.hpp.orig" (
copy %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\tls.hpp %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\tls.hpp.orig
)
sed -e 's/lib::ref(*m_context)/*m_context/' ^
< %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\tls.hpp.orig > %repo_location%\tmp\websocketpp\websocketpp\transport\asio\security\tls.hpp

As you can see I used also sed.exe to make this.
