我已经使用 docker 和 qemu 从我的 amd64 工作站为 PiCore64 编译了 canboat。具体来说，这是我的构建脚本：
#!/bin/sh
set -e
NAME=canboat
cd canboat
make all
cd ..
mkdir -p ./root/usr/local/bin/
cp canboat/rel/linux-aarch64/* ./root/usr/local/bin/

当我在 PiCore64 14.1.0 中加载此扩展时，我得到以下输出：

因此，显然可以找到所有必需的共享库，但我仍然对为什么收到错误感到困惑。有什么方法可以让我找到它正在寻找但找不到的东西吗？它缺少什么？
