環境 RHEL7.2
編譯src，這裏以igb網卡驅動爲例
[root@back rpm]# ls
igb-5.2.15_k-1.el7_2.src.rpm
step1：安裝編譯環境
網上所有文章都在說怎麼編譯，沒有人說(或者有人說，只是我沒有找到)編譯環境要安裝什麼包
yum install gcc rpm-build rpm-devel rpmlint make python bash coreutils diffutils patch rpmdevtools ==這是官方推薦的編譯環境
我還安裝瞭如下包
yum install kernel-devel
step2：使用rpm命令安裝igb-5.2.15_k-1.el7_2.src.rpm
[root@back rpm]# rpm -ivh igb-5.2.15_k-1.el7_2.src.rpm

這裏有一些warning，不用管它，我就用root編譯
[root@back ~]# cd rpmbuild/
[root@back rpmbuild]# ls
SOURCES SPECS
這裏只建立了兩個目錄，沒有建立RPM等目錄，也不用管，之後會自己建立的
step3：執行rpmbuild -bp 命令

可以看到，系統自動建立了這幾個目錄
[root@back rpmbuild]# ls
BUILD BUILDROOT RPMS SOURCES SPECS SRPMS
BUILD和BUILDROOT是編譯過程中需要的目錄，其中BUILDROOT是中間過程目錄
RPMS是編譯完成後生成的rpm包的存放地址
SOURCES是編譯過程在自動解壓後，存放解壓文件的目錄
SPECS目錄很重要，是你製作或修改spec文件的存放目錄
SRPMS是存放.src.rpm文件的目錄

根據報錯可以發現，這裏make是要找/usr/src/kernels/3.10.0-327.el7.x86_64目錄，而我當前的是[root@localhost SPECS]# ls -l /usr/src/kernels/3.10.0-229.el7.x86_64/目錄，這是因爲我當前的OS是7.1，而igb模塊的src.rpm是7.2版的(所以在make的時候會找3.10.0-327內核)
當前系統信息：
[root@localhost SPECS]# lsb_release -ia
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description: CentOS Linux release 7.1.1503 (Core)
Release: 7.1.1503
Codename: Core
rhel7.2系統的信息
[root@back x86_64]# lsb_release -ia
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 7.2 (Maipo)
Release: 7.2
Codename: Maipo
[root@back x86_64]# ll -l /usr/src/kernels/3.10.0-327.el7.x86_64/
所以該模塊需要在7.2下進行編譯
