在 Ubuntu 20.04.2 LTS 上编译/安装 RealTime 内核时出错

我需要安装一个 RealTime 内核才能使用 ROS2，我已经按照这个指导非常小心。但我总是得到同样的错误：

make[2]: *** [debian/rules:6: build] Errore 2
dpkg-buildpackage: Errore: debian/rules build subprocess returned exit status 2
make[1]: *** [scripts/Makefile.package:77: deb-pkg] Errore 2
make: *** [Makefile:1464: deb-pkg] Errore 2

例如我在终端上使用过的段落如下：

  • 新建一个文件夹，并在文件夹中输入：mkdir kernel && cd kernel
  • 下载内核和补丁wget https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.4.78.tar.gz：wget http://cdn.kernel.org/pub/linux/kernel/projects/rt/5.4/older/patch-5.4.78-rt44.patch.gz
  • 解压并解压缩这两个档案tar -xzf linux-5.4.78.tar.gz：gunzip patch-5.4.78-rt44.patch.gz
  • 进入内核文件夹：cd linux-5.4.78
  • 修补文件：patch -p1 < ../patch-5.4.78-rt44.patch
  • 使用旧的配置，在这种情况下，我有 2 个配置，所以我使用了：cp /boot/config-$(uname -r) .config对于我的情况$(uname -r)是5.4.0-70-generic
  • 在更新源代码的设置中添加了源，并按照指南中的说明安装了其他依赖项
  • 启用配置：yes '' | make oldconfig
  • 之后在菜单中启用不同的设置：make menuconfig
  • make -j使用nproc进行制作时发生错误deb-pkg

我该如何解决？

答案1

我遵循了本指南https://unix.stackexchange.com/a/294116/419660

sudo gedit .config

#在行前添加CONFIG_SYSTEM_TRUSTED_KEY并CONFIG_MODULE_SIG_KEY注释掉它们。运行后出现提示时选择所有默认值make -j numproc deb-pkg

我还需要关闭 BIOS 中的安全启动https://github.com/jakeday/linux-surface/issues/575

答案2

我在安装实时内核时多次遇到此错误，问题似乎出在编译为 debian 软件包上。我遵循的每个未编译为 debian 软件包的教程都有效。以下是我尝试过并有效的 2 个简单教程（您还需要安装 flex 和 bison）： https://hmenn.github.io/pages/UbuntuRT_patch.html https://stackoverflow.com/a/51709420

另外，您使用的是戴尔电脑吗？到目前为止，我发现遇到此问题的每个人都在使用戴尔电脑。

答案3

这看起来和我遇到的错误一样，解决方案是删除内核的这个功能。

SYSTEM_BLACKLIST_KEYRING = 否

答案4

你可以尝试一下

scripts/config --set-str CONFIG_SYSTEM_TRUSTED_KEYS=""
scripts/config --set-str CONFIG_SYSTEM_REVOCATION_KEYS=""
