Building LLVM of all components fails

[zky97]

Build and compile environment OS Windows11 python version 3.10.0 cmake version 3.23.1 ninja version 1.11.0 MinGW64 version 8.1.0_x86_64-posix-seh-rev0, GNU Make version 4.2.1 RAM 64GB cmake command：

Does anyone have information that this issue has been resolved?

@zky97 @robert-edward-lee I have tried the following. As a result, I guess that it can not be built with ver 8.1.0 of mingw64. So, I recommend trying the latest MinGw.

• MinGW64 version 8.1.0
  • is not able to build
• MinGW64 version 12.2.0
  • is able to build

[robert-edward-lee]

@akif999 MinGW 11.2.0 is able to build too

but if you comment out this line, everything will be built too, heh)
