This problem has nothing to do with redmine itself, I have found at least two ways to solve it, using the mysql library compilation, or using the ucrt64 library compilation, but need to manually modify the code

Thanks a lot for your help!

Using the mysql library compilation, or using the ucrt64 library compilation, but need to manually modify the code.

Can you give me more detail on how to do mysql library compilation and which line of code needs to be modified.
