I´m trying to use the boost Library example for a websocketserver (https://www.boost.org/doc/libs/develop/libs/beast/example/websocket/server/async/websocket_server_async.cpp) inside a DLL Project. I want to compile it into a single DLL.
It´s completely working inside a console Application, but if I move the code to my DLL Project I can´t even use the needed includes. This problem also appears on blank dll Projects with the same include configuration as the console app.
The include "boost/beast/core.hpp" failes with the following errors (all in the file "boost\beast\core\impl\file_stdio.ipp" in line 244):
- '(': illegal token on right side of '::'
- type 'unknown-type' unexpected
- syntax error: 'unknown-type' should be preceded by '('
- syntax error: ')'
- syntax error: missing ';' before '{'
I´m using the boost Version 1.72.0
I´ve got no idea what the difference between the console App and an DLL is.
Is it even possible to use the library properly for a DLL? If yes, do you have any ideas what I´m doing wrong?
Edit: The code causing the error inside the boost library is the following:
if(offset > static_cast<std::uint64_t>(std::numeric_limits<long>::max()))
{
ec = make_error_code(errc::invalid_seek);
return;
}
especially the "::max()" causes the error
