在 Linux CPU 负载中包括 glibtop

Question

这是我的代码，用于查看 Linux 中的 CPU 负载，但我有一些错误！我下载了 glibtop 并将其放在与我的程序相同的目录中，但我有这些错误！

    `#include "stdio.h"
     #include "glibtop.h"
     #include "glibtop/cpu.h"

     int main(){
     glibtop_init();
     glibtop_cpu cpu;
     glibtop_get_cpu (&cpu);
     printf("CPU TYPE INFORMATIONS \n\n"
     "Cpu Total : %ld \n"
     "Cpu User : %ld \n"
     "Cpu Nice : %ld \n"
     "Cpu Sys : %ld \n"
     "Cpu Idle : %ld \n"
     "Cpu Frequences : %ld \n",
     (unsigned long)cpu.total,
     (unsigned long)cpu.user,
     (unsigned long)cpu.nice,
     (unsigned long)cpu.sys,
     (unsigned long)cpu.idle,
     (unsigned long)cpu.frequency); 
     return 0;
     }`

我的错误是：

cpuLoad.c:2:21: error: glibtop.h: No such file or directory
In file included from cpuLoad.c:3:
glibtop/cpu.h:25:21: error: glibtop.h: No such file or directory

你知道问题是什么吗？我不知道我应该如何告诉linux我的.h文件的路径！

Answer 1

gcc -I. 等

手册说：

-I dir 将目录dir添加到要搜索头文件的目录列表中。

Answer 2

我刚刚尝试了上面相同的代码，它的工作就像一个魅力。

$ gcc -Wall -g -Wextra main.c $(pkg-config --cflags --libs libgtop-2.0)
$ ./a.out
CPU TYPE INFORMATIONS

Cpu Total : 695672439
Cpu User : 4072158
Cpu Nice : 21564
Cpu Sys : 1523271
Cpu Idle : 687079036
Cpu Frequences : 100

它位于 Debian Unstable amd64 上，带有 libgtop2-dev 2.28.4-3 和 gcc 4.7.1。
