Error loading extension: res//DodgeTheCreeps.gdextension

[mareksubocz]

I've tried to run DodgeTheCreeps demo on M1 Macbook Pro. The project built and the game started, but nothing happened after clicking the "START" button inside the game and following errors appeared:

Can't open dynamic library: /Users/mareksubocz/it/gdext/examples/dodge-the-creeps/godot/../../../target/debug/libdodge_the_creeps.dylib, error: dlopen(/Applications/Godot.app/Contents/MacOS/../Frameworks/libdodge_the_creeps.dylib, 0x0002): tried: '/Applications/Godot.app/Contents/MacOS/../Frameworks/libdodge_the_creeps.dylib' (no such file).

The steps I took to set the project up were:

brew install godot
git clone https://github.com/godot-rust/gdext && cd gdext
export GODOT4_BIN=/Applications/Godot.app/Contents/MacOS/Godot
export LLVM_PATH=/Library/Developer/CommandLineTools/usr/bin
cargo build # successfully
cd examples/dodge-the-creeps
cargo build # successfully
godot # to run the game

Is there something I overlooked?

[Bromeon]

Could you check the contents of the directory gdext/examples/dodge-the-creeps/godot/../../../target/debug?

Also, try specifically cargo build -p dodge-the-creeps (although that shouldn't be necessary).

[mareksubocz]

Also, cargo build -p dodge-the-creeps didn't fix anything.

[Bromeon]

Is there only the dynamic library for godot_macros? Why not for godot?

[mareksubocz]

Sorry, I'm not sure what you mean

EDIT: I showed all of the contents of the debug folder if that's what you mean. Not sure why there are no libraries for godot itself.

[lilizoey]

try to cd into examples/dodge-the-creeps/rust before building

[Bromeon]

Can you do the following, and paste the full command line + output? Navigate to the gdext directory, then:

rm -rf target
cargo update
cargo build
ls -la target/debug

[mareksubocz]

try to cd into examples/dodge-the-creeps/rust before building

That didn't change anything.

Can you do the following, and paste the full command line + output? Navigate to the gdext directory, then:

rm -rf target
cargo update
cargo build

[Bromeon]

Thanks! This is very strange, it clearly compiles both godot and dodge-the-creeps crates, yet doesn't generate the cdylib files for them. For some reason, it does for macros though....

Do you get more information about cargo build output if you clean again, and then use the -v (verbose) flag? Please only list the godot-* and dodge-the-creeps crates, otherwise it's too much output 😅

[Bromeon]

Ah, there they are!

In your .gdextension file inside examples/dodge-the-creeps/godot, it looks like you need two extra lines:

macos.debug.aarch64 = "res://../../../target/aarch64-apple-darwin/debug/libdodge_the_creeps.dylib"
macos.release.aarch64 = "res://../../../target/aarch64-apple-darwin/release/libdodge_the_creeps.dylib"

(maybe remove the existing macos entries for now).

I'm actually 100% unsure about "aarch64" part. Might also be "arm64" or something else. Could you try a few things?

It would likely work without any prefix (just macos.debug = "..."), however that means that macOS on other architecture may break.

[mareksubocz]

Nice! That got rid of the problem, thank you so much!

I suspect however there is another thing to solve, the sprites don't display properly:

EDIT: FYI, the setting that works is macos.debug.arm64 and macos.release.arm64

[Bromeon]

Nice! That got rid of the problem, thank you so much!

Which architecture was it? How does your .gdextension file look now?

Btw, you should also be able to get the name through Engine::get_architecture_name.

I suspect however there is another thing to solve, the sprites don't display properly:

Can you open the editor once, save all scenes and see if anything changes? From the command line, you can navigate to the dodge-the-creeps/godot directory and run godot4 -e.

[mareksubocz]

architecture is arm64.

DodgeTheCreeps.gdextension:

[configuration]
entry_symbol = "gdext_rust_init"

[libraries]
linux.debug.x86_64 = "res://../../../target/debug/libdodge_the_creeps.so"
linux.release.x86_64 = "res://../../../target/release/libdodge_the_creeps.so"
macos.debug = "res://../../../target/debug/libdodge_the_creeps.dylib"
macos.release = "res://../../../target/release/libdodge_the_creeps.dylib"
windows.debug.x86_64 = "res://../../../target/debug/dodge_the_creeps.dll"
windows.release.x86_64 = "res://../../../target/release/dodge_the_creeps.dll"
macos.debug.arm64 = "res://../../../target/aarch64-apple-darwin/debug/libdodge_the_creeps.dylib"
macos.release.arm64 = "res://../../../target/aarch64-apple-darwin/release/libdodge_the_creeps.dylib"

saving the scenes triggers the same warnings. Do you want me to paste the outputs of godot4 -e? It doesn't fix the warnings.

[mareksubocz]

Let me know if you need it as text, as there is quite a lot of it :)

[Bromeon]

Also changing the scenes slightly (in insignificant ways) + saving doesn't update the files? You should see changes in git diff for Mob.tscn and Player.tscn...

[mareksubocz]

It does update the files, but the warnings stil remain. I'm not sure if Player.tsch is updated, as it is not present in git diff.

[Bromeon]

From your commit hashes:

index 32c2394..1775a2f

What are those? Looks like none of the recent gdext commits has them.

Does it also happen with latest master (commit 08c65941ce544b2255d5b09168c7e9944a9dd454)?

[mareksubocz]

I am currently using the latest commit. I don't know what those hashes mean, but i reverted all changes and compiled everything again and, despite still seeing some warnings, everything worked and I was able to play the game! Thank you so much :D Love the support of this project! The issue is ready to close.

[Bromeon]

Happy to hear it worked 🙂 Also, if you encounter more questions in the future, feel free to join or Discord, can sometimes be a bit faster 😎

If you don't mind, I will keep this issue open until I added support for aarch64 architecture on macOS. Thanks a lot for reporting!
