我最近在安装“keynav”（一种用于键盘控制鼠标指针的实用程序）时遇到了困难。第一个问题：
keynav.c:29:17: fatal error: xdo.h: No such file or directory
#include <xdo.h>
^
compilation terminated.
一旦解决了这个问题，第二个问题就解决了：
cc keynav.o -o keynav -lcairo -lXinerama -lglib-2.0 -lXext -lX11 -lXtst -lglib-2.0 -lxdo; \

不过，我现在已经成功安装了，所以我会发布答案，以防其他人需要它！
答案1
因此第一个问题是由于没有发展xdo 库的版本，并由
dnf install libxdo-devel
第二个问题是由于文件中keynav.c有一堆来自xdo.h头文件的错误命名的调用造成的。（我假设这里的版本之间存在一些不一致，但还没有调查过。）
无论如何，这些问题都可以手动修复，方法是在头文件中找到名称相似的函数，然后在源文件中编辑名称。以下是diff修改后的结果和原始结果：

如您所见，只需要更改函数的名称，而不是参数。
[如果您不知道diff：在这种情况下，每行上方的行---都是新的（以 开头<），而每行下方的行---都是已更改的旧行（以 开头>，并且您也需要在keynav.c文件中进行更改。）]
希望有帮助！
