unable to find the sources of your current Linux kernel.，sourceskernel

運行

sh ./VBoxLinuxAdditions.run

時FAILED，查看日誌：

/tmp/vbox.0/Makefile.include.header:97: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again.  Stop.Creating user for the Guest Additions.Creating udev rule for the Guest Additions kernel module.

意思是說沒有核心源檔案，解決的辦法是運行

yum instal gcc.i686 kernel.i686 kernel-devel.i686reboot

分別是編譯器，核心，核心標頭檔以及Makefile，然後再重啟，讓系統從新的核心檔案選項啟動。再運行

sh ./VBoxLinuxAdditions.run

就可以編譯成功了。
