Godot Version
4.3 (Arch Linux)
Question
I’ve been using Godot for about a week, starting with version 4.2.2, and had no issues using GDExtension with C++. However, after upgrading to version 4.3, I encountered a problem when trying to compile my GDExtension for Android.
When I compile the Godot C++ binding (godot-cpp) with scons platform=linux api_file=4.3, it compiles without any issues. But when I try to compile my GDExtension with scons platform=android, I get a SCons error during linking that says:
scons: *** [libgodot-cpp.android.template_debug.arm64.a] sh: Argument list too long
scons: building terminated because of errors.
This error did not occur in version 4.2.2, where I was able to successfully compile both Linux and Android versions of my GDExtension. Interestingly, using scons platform=linux for my GDExtension still works fine, so the issue seems specific to Android (ARM64) when linking against the Godot 4.3 C++ binding (godot-cpp).
Since I’m new to Godot (just 3 days in) and its build system (SCons), I might be making a mistake, but given that everything worked in 4.2.2, I suspect it could be an issue with the new version. I’m not new to game development, and I consider myself a competent C++ programmer, so I’m not completely lost.
Thank you for any help you can provide. Here’s my setup and the exact error message:
