Error: unhandled exception: index out of bounds [IndexError]

This may happen due to a mismatch between compiler package in your nimble repository versus the Nim version you used to compile the nakefile. Try to do the following:

1. Run nimble install in Nim's folder.
2. Run rm nakefile in the project's folder.
3. Run nake build.

compiler for 0.18.1 was already satisfied so in addition i also did:
nimble install compiler@#head

This brought me one step further to this:

Generating audio_effect.nim...
Generating mesh_instance_2d.nim...
Generating editor_file_system.nim...
Generating audio_effect_stereo_enhance.nim...
Generating label.nim...
   Warning: Package 'stub' has an incorrect structure. The top level of the package source directory should contain at most one module, named 'stub.nim', but a file named 'fpscounter.nim' was found. This will be an error in the future.
      Hint: If this is the primary source file in the package, rename it to 'stub.nim'. If it's a source file required by the main module, or if it is one of several modules exposed by 'stub', then move it into a 'stub/' subdirectory. If it's a test file or otherwise not required to build the the package 'stub.nim', prevent its installation by adding `skipFiles = @["fpscounter.nim"]` to the .nimble file.

Where does the 6713e70d756c04dbd54d32feb78ae62eed6bda4e commit come from? It's not in the devel tree of Nim.

I've compiled godot-nim-stub successfully with latest devel commit - c12726d41e7df20bce452b6d7f8959d8b9e401a9.

Also, it's better not to use #head with nimble because of nim-lang/nimble#318. nimble install -y will reinstall the version even if it already exists, so you should use that after updating devel.

So I'd suggest to do this:

1. Compile the latest Nim.
2. Run nimble install -y in Nim's folder.
3. Run nake clean in the project's folder.
4. Run nake build.

Notice that even though the code compiles successfully, it doesn't run well due to a number of breaking changes and regressions introduced in latest Nim. I'll adapt godot-nim as soon as the bugs are fixed in Nim itself. For now I'd suggest to use a stable version.
