Fedora 20源码安装Xen4.3.0

<

blockquote contentScore=”2033″>
1.出现比较多的一个问题是权限不够，这是由于xen-4.3.0是拷贝过来，一些权限发生了变化。例如：
错误：make[3]: execvp: /home/chenchao/xen-4.3.0/tools/include/../../tools/cross-install: 权限不够
解决方法：进入到相应的目录，修改相应文件的权限即可。

2.编译参数不被识别
错误：cc: 错误：unrecognized command line option ‘-combine’
解决方法：/home/chenchao/xen-4.3.0/tools/firmware/seabios-dir-remote/Makefile中去掉编译参数-combine

3.编译出错
错误：Traceback (most recent call last):
File “./tools/layoutrom.py”, line 630, in
main()
File “./tools/layoutrom.py”, line 607, in main
info16 = parseObjDump(infile16, ‘16’)
File “./tools/layoutrom.py”, line 538, in parseObjDump
relocsection = sectionmap[sectionname]
KeyError: ‘.text.asm.out/../src/smp.c.77’
解决方法：加LC_ALL=C make编译，上网查到的原因是：语言设置为UTF-8。

4.缺少头文件库
错误：/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
# include < gnu/stubs-32.h>
解决方法：64bit系统编译32bit程序，遇到的问题，终端执行
sudo yum install glibc-devel.i686
sudo yum install libgcc.i686

5.编译命令not find
错误：/bin/sh: line 1: patch: command not found
解决方法：sudo yum install patch.x86_64

6.缺少lib库
错误：glib-2.12 required to compile QEMU
解决方法：sudo yum install glib2-devel.x86_64

7.没有该文件
错误：/tmp/qemu-conf-5475-3115-17647.c:1:17: fatal error: SDL.h: No such file or directory
#include < SDL.h>
解决方法：sudo yum install SDL-devel.x86_64
