Unable to compile helloworld.cpp example (from Visual Studio Code doc)

[slolo2000]

Hello,

I have created a post on github for "Vs Code cpptools".
You can find the post here : microsoft/vscode-cpptools#13086

As you can see, I am not able to compile a simple helloworld with the last version on MYSYS2 msys2-x86_64-20241208.exe
Available here (msys2-x86_64-20241208.exe

But I can compile a simple helloworld in c (with gcc)

Is there any minimum requirement with the last version which make the error message appears?

With a previous install program (msys2-x86_64-20230526.exe) I have no problem.
Available here : https://github.com/msys2/msys2-installer/releases/download/2023-05-26/msys2-x86_64-20230526.exe

Thanks in advance for your help.

Can you compile the helloworld file in ucrt64 environment without vscode?

[slolo2000]

I am rather new to Msys2 but after some research here is what I did:
I Double clicked on the file "D:\Dvpt\msys64\ucrt64.exe" => It opened a command window.

I have test 2 command lines (because I have 2 test projects.
The first one (c project)
gcc.exe -fdiagnostics-color=always -g D:\\Project\\c\\helloworld.c -o D:\\Project\\c\\helloworld.exe
It works very well 👍

The second one (c++ helloworld project)
g++.exe -fdiagnostics-color=always -g D:\\Project\\cpp\\helloworld.cpp -o D:\\Project\\cpp\\helloworld.exe
It works very well too 👍

So I'm even more confused about the fact that it works when outside the Msys execution environment (UCRT64) I have an error message (only for compiling in C++)

Any idea?

Could you please translate the error message in the screenshot?

[slolo2000]

The translation give this:

---

cc1plus.exe - Entry point not found

The procedure entry point crc32_combine was not found in the dynamic link library D:\Dvpt\msys64\ucrt64\bin..\lib\gcc\x86_64-w64-mingw32\14.2.0\cc1plus.exe.

Ok

In a MS DOS command:
D:\Project>gcc.exe -fdiagnostics-color=always -g D:\Project\cpp\helloworld.cpp -o D:\Project\cpp\helloworld.exe
Works well.

D:\Project>g++.exe -fdiagnostics-color=always -g D:\Project\cpp\helloworld.cpp -o D:\Project\cpp\helloworld.exe
Does not work and display the message above.

It is like it misses a path in environment variables which should initialized by ucrt64 environment.

[Biswa96]

Does adding D:\Dvpt\msys64\ucrt64\bin in PATH environment variable work?

For example, set PATH=D:\Dvpt\msys64\ucrt64\bin;%PATH%

[slolo2000]

As explained here I already added this folder to my PATH environment variable.

The strangest thing is that everything works perfectly with version msys2-x86_64-20230526.exe of Msys2 but not the latest version msys2-x86_64-20241208.exe

[slolo2000]

I have done a test to update from msys2-x86_64-20230526.exe to the latest version with the command line:
pacman -Suy
I have exactly the same problem as if I have done a fresh install.

I assume the latest version must use a path to files that is not in the system path.
Any help is welcome.

Hello,

With the help of the creators of the vscode-cpptools extension the origin of the problem has finally been found.
You can see the detail here microsoft/vscode-cpptools#13086 (reply in thread)

As you can see, there is a name conflict with a dll (zlib1.dll) between the Intel wifi driver and Msys2 (or a version problem at Intel which may have a very old version of a file).

What do you suggest to me?
Replace the Intel driver dll or move the "msys64\ucrt64\bin" folder higher in my path environment variables? (hoping the driver still works well).
