Question

我正在尝试编译vmware vmci示例程序。该计划分为两部分

a）内核模块 b）示例数据报程序

当我编译该数据报程序时，我得到了这些错误：

gcc -I headers_path datagramApp.c
/tmp/cc6KkQ4a.o: In function `main':

Answer 1

您需要链接（共享）对象以获取VMCI的用户界面

AFAICT这是来自Vmware（？）的专有API，你应该安装[1]

典型的编译行看起来更像是：

gcc -I <headers_path> datagramApp.c -lvmci

注释

用类似的东西替换header_path（取决于构建模块的位置）
- 的/ usr / src / linux中/包括
- /选择器/ VMware /包括
-lvmci会建议在您的库路径中提供libvmci.so（请记住sudo ldconfig -a，可选择包含-L/path/to/libs以使gcc / ld找到它们）

[1]也许是Custom Installation of VMware Tools的一部分？
