Cannot initialize a parameter of type 'const tchar *' (aka 'const wchar_t *') with an lvalue of type 'const char *'
When using clion to build my project, only then # include
Here is the process：

Hi @nightvoyager-xxs, Could you please try to build oneTBB with this compiler?
Hi, I'm sorry to revive this issue but did you manage to find the solution to this error? I'm having the exact same problem. @Data-Adventure
Hi @exldna ,
Thank you for reporting this. Can you please provide a reproducer. I tried on mingw environment on Windows and couldn't reproduce it. I also need to know the cmake build cmd you used - especially the generator option (-G) set by you.
I am trying to run the example code from the MS docs, and I get the following compilation error:
Creating a View Within a File
https://learn.microsoft.com/en-us/windows/win32/memory/creating-a-view-within-a-file
Severity Code Description Project File Line Suppression State Error (active) E0144 a value of type "const wchar_t *" cannot be used to initialize an entity of type "TCHAR *" FileIO_example_01 K:\Software Development\aaa_PlayGround\20240328_WinFileIO\WinFileIO_01\FileIO_example_01\FileIO_example_01.cpp 45

EDIT: I managed to get it to compile.
//TCHAR * lpcTheFile = (TCHAR *) TEXT("fmtest.txt"); // the file to be manipulated
const TCHAR * lpcTheFile = (TCHAR *) "fmtest.txt"; // the file to be manipulated
When I ran the executable, the file name for the test file ("fmtest.txt") was mangled, and the generated content is hex/binary from what I can tell.
I can reproduce the issue on latest master under mingw. Specifically, I used a fresh install of mingw winlibs, and the mingw makefiles generator for the initial setup. (I can build tbb using the visual studio toolchain, but can't even link with the devel libraries under mingw once they are installed due to this issue.)
