VS2015 / 2017 中的 TRACE 宏无法编译 - 我需要包含什么？

Question

I have an SDK for some Hardware I need to implement
I use The MFC Class they provide and created a windows console application. They heavily rely on the Trace Macro so i cant simply comment them out.

• I already manually installed the ATL + MFC Component for visual C++

• I installed the 2015 Compiler (as i read they changed something ...)

• I disabled precompiled headers

• I tried "switching" some options in Project properties, but that did not yield anything different :(

  TRACE(_T("PS10DLL not found\\n"));

I would expect to compile smoothly but the Error (they used it alot) is:
error C3861: "TRACE": Identifier was not found.

Answer 1

According to your issue, you are creating a windows console application? TRACE is used in the MFC support program and cannot be used in the WIN32 Application program.

TRACE is a definition in MFC. In Win32 code, you can directly use OutputDebugString to achieve the same effect.

I suggest you could refer to the link: How can I use the TRACE macro in non-MFC projects?
