Install Live555 missing member "test" of "std::atomic_flag" | install Live555 using C++20

I am currently trying to compile Live555 to use it in a C++ project. Unfortunately, I am not even able to compile it properly.

I have tried to compile it like in the documentation from here which failed because of the error "GroupsockHelper.cpp(46): fatal error C1083: file (Include) cannot be accessed: "ifaddrs.h": No such file or directory" (translated).

This bug is fixed when using vcpkg. But using vcpkg leads to another error. Running "vcpkg install live555:x64-windows" will result in the error: "BasicUsageEnvironment\BasicTaskScheduler.cpp(191): error C2039: 'test': is not a member of 'std::atomic_flag'".

When I followed this error, I came across this where it says that "test" is part of "std::atomic_flag" since C++20. Now I fail to get any information on how to compile it with the C++20 Standard. Some sources (e.g. this) state, that the the C++ Standard should be changed in Visual Studio, which seems wrong to me and also does not work. Then I also tried this command (which I found somewhere I cant recap) "vcpkg install live555:x64-windows --feature-flags=manifests,c++latest"/ "vcpkg install live555:x64-windows --feature-flags=manifests,c++20". This does not work either. It always leads to the C2039 error.

I think that I dont really understand what the MSVC is and what to do that MSVC/CMake uses C++20 when running vcpkg.

I am using Visual Studio 2022 Enterprise on Windows 10. MSVC installation in VS is v143. The cmd says it runs on "Visual Studio 2022 Developer Command Prompt v17.6.4" for x64.

I hope that this makes it roughly clear where my actual problem lies and why I cannot solve it by myself.

I tried:

  • to follow the Live555 documentation,
  • using vcpkg with "vcpkg install live555:x64-windows"
  • to change the VS properties like here
  • to used vcpkg flags like "vcpkg install live555:x64-windows --feature-flags=manifests,c++20"
  • of course to google how to use C++20, but to no avail

The cmd:

Solution

  • In the project's CMakeLists.txt add the following line (or edit an existing one):

    set(CMAKE_CXX_STANDARD 20)

    That configuration setting changes the compiler options/features. For example, that option will add the /std:c++20 flag to the Microsoft C++ compiler. Equivalent flags are set for other compilers.
