You mention a cpp file. Are you trying to build this with C++?
Have you included StdLib\StdLib.inc in your project’s .dsc file?
The error you are seeing was added to EfiCdefs.h to detect configuration
errors. When it occurs, you can be sure that your project’s build files are
not configured correctly.
Look at StdLib\StdLib.dsc and AppPkg\AppPkg.dsc for examples of .dsc files for
using StdLib.
Also, look at some of the application .inf files in AppPkg for examples of
properly formed .inf files.
These files have comments describing the constructs that are specific to StdLib.
Note that C++ is not currently supported, nor is it tested.
Make sure that you have read, and understand, the StdLib\ReadMe.txt file. If
you don’t follow the instructions in that file, builds with StdLib will either
fail or will not work as expected.
Sincerely,
Daryl McDaniel

Subject: [edk2] A compile fail problem when I include stdio.h into the cpp file
Hello everyone,
I have met a compile problem when I include stdio.h into the cpp file.
The error message is:
c:\myworkspace\StdLib\Include\sys/EfiCdefs.h(330) : fatal error C1189: #error :
You must specify /Zc:wchar_t- to the compiler to turn off intrinsic wchar_t.
Hence, I followed the tip to add the /Zc:wchar_t- into the BuildOptions of my
inf file.
However, this compile error still occurs, unless I direct delete the 330 line
of the EfiCdef.h.
It seems an issue.
Thanks,
