testptp.c 是否可以为其他人编译？

我正在尝试编译一个脚本来帮助我测试 LinuxPTP。 testptp.c 文件是帮助执行此操作的脚本。它内置于 Linux 内核中。但是，我无法编译它。这只是我吗？我看到很多人在谈论这个实用程序脚本，但我看到的唯一在线教程是：https://docs.nvidia.com/networking/display/NVIDIA5TTechnologyUserManualv10/Testptp

它告诉您使用 gcc 编译 testptp.c。我使用以下命令进行编译，在只有 testptp.c: 的目录中gcc testptp.c -o testptp。我还从 git 中提取了 Linux 内核并进入tools/testing/selftests/ptp并运行make。两者产生相同的结果。

这是我的输出：

我运行的是 Ubuntu 20.04。 Linux 内核版本：5.15.0-53-generic

这对其他人有用吗？

答案1

/usr/include/linux/ptp_clock.h覆盖文件以下文件似乎对我有用。
