LINK : error LNK2001: unresolved external symbol WinMain referenced in function #WinMain$exit_thunk (EC Symbol)? (ARM64EC / VS 2022)

Hi
Visual C++2022 with ARM64EC as target
wWinMain is defined and linking with Windows as subSystem
=>
linker error:
2>LINK : error LNK2001: unresolved external symbol wWinMain (EC Symbol)
2>MSVCRT.lib(exe_winmain.obj) : error LNK2019: unresolved external symbol WinMain referenced in function #WinMain$exit_thunk (EC Symbol)

This works for ARM64 / x86, but not for ARM64EC
Any Idea? a library issue?

Thanks
Yvan

May I know what kind of C++ project did you create? Could you provide the steps to reproduce the problem LNK2019?

Thanks for taking time to report this problem with us. Currently, STEINBERG is not supported here. You can go to github for support.

Thanks for your feedback, I am from Steinberg and the problem is not in the Steinberg VST SDK but in Visual C++ 2022 with ARM64EC.. and mWinMain.
