![ubuntu 内核 5.4.0-42.46 构建期间出现编译错误](https://linux22.com/image/939056/ubuntu%20%E5%86%85%E6%A0%B8%205.4.0-42.46%20%E6%9E%84%E5%BB%BA%E6%9C%9F%E9%97%B4%E5%87%BA%E7%8E%B0%E7%BC%96%E8%AF%91%E9%94%99%E8%AF%AF.png)
我通过 下载了 ubuntu 源代码git clone git://kernel.ubuntu.com/ubuntu/ubuntu-focal.git
。因为我想使用特定的版本,所以我执行了 git checkout Ubuntu-5.4.0-42.46 (此版本是 ubuntu 安装 .iso 中使用的版本。请参阅此处的相关问题:我应该使用哪个 ubuntu 源版本来添加一些调试打印?(用于 ubuntu 启动调试))
git-checkout 之后git log
显示以下结果:
commit 98c4545e2d65ed35c31056f72c4da20f6b5ea0d0 (HEAD, tag: Ubuntu-5.4.0-42.46)

为了构建内核,我执行了ARCH=arm64 CROSS_COMPILE=aarch64-none-elf- make defconfig
和ARCH=arm64 CROSS_COMPILE=aarch64-none-elf- make -j24 Image
。但这会给我下面的编译错误。可能是什么问题?

当我对 linux-5.4.21 源执行相同操作时,它可以编译成功。

我发现 ubuntu 有自己的构建整个 ubuntu (包括内核)的方法。如下所示:https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
arm64 案例的正确方法是(来自上面的页面)
LANG=C fakeroot debian/rules ARCH=arm64 clean
# quicker build:
LANG=C fakeroot debian/rules ARCH=arm64 binary-headers binary-generic binary-perarch
# if you need linux-tools or lowlatency kernel, run instead:
LANG=C fakeroot debian/rules ARCH=arm64 binary
您可以使用以下命令(从上面的页面)添加调试信息:
sudo apt-get install pkg-config-dbgsym
LANG=C fakeroot debian/rules clean
LANG=C fakeroot debian/rules binary-headers binary-generic binary-perarch skipdbg=false
