Error running the emulator on Windows: code: 126, kind: Uncategorized, message: "The specified module could not be found."

[tomcss]

The compiling went without problems, no errors or warning, using 'cargo build --release'. But when I try to run the application using 'cargo run --release', I get the following result at the end of this message.

I presume this is because it's not finding the VDP modules, but those didn't compile and didn't generate any module files.

Running make myself for the VDP yields a file not found response:

Is g++ in the path? And did you get the git submodules? Git submodule init and git submodule update.

[tomcss]

No, I just discovered it's not. I added ming64 to the path instead of mingw64.

It compiled, I copied over the .so files to firmware and it's running fine now.

I hope my incompetence will be of use to other people running into the same issue.
