Is it possible to build a version from source code?

[Little-Data]

Great open source project, thanks for your efforts.
I'm trying to create a Simplified Chinese localization for this project and I get errors that say I can't build when debugging.
Here is the error log:

Can you consider adding localized language support?
I hope that I can build a version from the source code to debug.
