windows mingw64 compile fail

[aiaimimi0920]

My step：

git clone https://github.com/google/glog.git
cd glog

cmake -S . -B build -G "Unix Makefiles"
cmake --build build

An error occurred:

Everything is normal when compiling on Ubuntu. Is there any special operation required for compiling on the Windows platform?

I use MSYS2 MINGW64、windows 11 、 Latest code 54b2c17172dc39892de41ed2b3e72902e19ce0c0

Hope to receive some guidance, thank you in advance

Could you please provide the full output of cmake --build build --verbose?

You need to run CMake in the MINGW64 / MSYS2 shell not MSYS / MSYS2. You may need to install the mingw-w64-x86_64-cmake package. See our MinGW github action for reference:

https://github.com/google/glog/blob/cafba580ec4faeeb8e61a97f91819fd0db3205a0/.github/workflows/windows.yml#L179-L186

Thanks for your guidance, it helps a lot.

I am indeed using MINGW64/MSYS2. It should be caused by not installing the software package mingw-w64-x86_64-cmake. Because I did not encounter this problem when compiling other projects normally, I did not take it into consideration.

All in all, thank you very much
