Question

我已經安裝在CentOS安裝kernel-devel，仍然找不到內核頭

# yum install kernel-devel 
Loaded plugins: fastestmirror, ovl 
Setting up Install Process 
Loading mirror speeds from cached hostfile 
* base: mirrors....net 
* extras: ... 
* updates: mirrors.....net 
Package kernel-devel-2.6.32-642.15.1.el6.x86_64 already installed and latest version 

但是還是頭文件都沒有發現海灣合作委員會：

# cat testkmem.c 
#include<sys/types.h> 
#include<sys/kmem.h> 
int main(){ 

    return 0; 
} 

# gcc testkmem.c 
testkmem.c:2:21: error: sys/kmem.h: No such file or directory 

如何解決這個編譯問題，任何額外的yum包所需？

Answer 1

你知道定位命令嗎？

$ locate kmem.h 
/usr/src/kernels/3.10.0-514.10.2.el7.x86_64/include/config/memcg/kmem.h 
/usr/src/kernels/3.10.0-514.10.2.el7.x86_64/include/trace/events/kmem.h 

:-)，我覺得你的PATH有錯誤。
