[StackOverflow/docker] Compling libnm for ARM64

### ROOT CAUSE The issue arises because the `libnm` library (part of NetworkManager) is not being cross-compiled for ARM64 architecture. This could be due to missing dependencies, incorrect configuration, or incomplete toolchain setup for ARM64. The error likely occurs during the build phase when the compiler attempts to generate ARM64 instructions. ### CODE FIX To compile `libnm` for ARM64, follow these steps: 1. **Set up the ARM64 cross-compilation environment**: Ensure the ARM64 toolchain (e.g., `aarch64-linux-gnu-gcc`) is installed: ```bash sudo apt-get install binutils-aarch64-linux-gnu gcc-aarch64-linux-gnu ``` 2. **Configure the build for ARM64**: Use `meson` (if using the Meson build system) to cross-compile: ```bash meson build --cross-file arm64-cross.xml ``` Create `arm64-cross.xml` with: ```xml linux x86_64 linux arm64 gcc aarch64-linux-gnu-gcc aarch64-linux-gnu-ar aarch64-linux-gnu-strip ``` 3. **Build and install**: ```bash cd build ninja ninja install ``` If using `autotools`, set `CFLAGS` and `CXXFLAGS` for ARM64: ```bash CFLAGS="--target-arch=arm64" ./configure --host=aarch64-linux ``` **Note**: Verify dependencies are available for ARM64 (e.g., `libglib2.0-dev:arm64`). Adjust paths in the cross-file if necessary.
