Cannot run g++ in powershell but can run in MSYS2 UCRT64

[CaliInn-Li]

I have an error when attempting to compile a simple C++ file in powershell, it will popup a message: "The procedure entry point clock_gettime64 could not be located in the dynamic link library C:\msys64\ucrt64\bin..\lib\gcc\x86_64-w64-mingw32\15.2.0\cc1plus.exe."

However, if I run this command: "g++ test.cpp -o test.exe" in MSYS2 UCRT64 shell, not powershell, everything is fine. And if I want to run the program in the powershell which compiled in MSYS2 UCRT64 shell, it will still give the same error message: "The procedure entry point clock_gettime64 could not be located in the dynamic link library C:\msys64\ucrt64\bin\libstdc++-6.dll."

MSYS2 version:

$ pacman -Q msys2-runtime mingw-w64-ucrt-x86_64-gcc
msys2-runtime 3.6.5-1
mingw-w64-ucrt-x86_64-gcc 15.2.0-8

My system is:

OS Name: Microsoft Windows 11 Home Chinese Edition

OS Manufacturer: Microsoft Corporation

OS Configuration: Standalone Workstation

OS Build Type: Multiprocessor Free

I have already added C:\msys64\ucrt64\bin to PATH:

PS C:\Users\lph12> $env:Path -split ';' | Select-String "msys64"

C:\msys64\ucrt64\bin

Thanks for your help!

I get the answer! it's the same issue as #24355.
This is caused by a version mismatch of libwinpthread-1.dll. Newer versions of GCC (15.x) require a specific implementation of clock_gettime64 found in the latest MSYS2 libraries. However, another software on system (e.g., Wireshark, Git for Windows, or Android SDK) contains an older version of the same DLL, and its path is prioritized in your system's PATH environment variable.
I ran the command:

PS C:\Users\lph12> where.exe libwinpthread-1.dll

C:\Program Files\Wireshark\libwinpthread-1.dll

C:\msys64\ucrt64\bin\libwinpthread-1.dll

You can see libwinpthread-1.dll in wireshark is priorer than the one in msys64. So you should move up the path to the top.
