Ubuntu amd64下Xen编译错误解决方案(like centos 7)
 



 

• 编译环境
  

Ubuntu 14.04 64位

• Python错误
  

Traceback (most recent call last): File "./tools/layoutrom.py", line 630, in <module> 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'
原因是：语言设置为UTF-8
解决方法：使用 LC_ALL=C make命令进行编译

• cdefs.h
  

fatal error: sys/cdefs.h: No such file or directory
原因是：使用的是amd64版本的Ubuntu
解决方法：安装libc6-dev-i386软件包
 

• makeinfo
  

WARNING: `makeinfo' is missing on your system. You should only need it if
you modified a `.texi' or `.texinfo' file, or any other file
indirectly affecting the aspect of the manual. The spurious
call might also be the consequence of using a buggy `make' (AIX,
DU, IRIX). You might want to install the `Texinfo' package or
the `GNU make' package. Grab either from any GNU archive site.
原因：未安装makeinfo软件包
解决方法：安装texinfo

• tmpback.c语法错误
  

tpmback.c: In function 'tpmif_change_state':
tpmback.c:350:4: error: format '%d' expects argument of type 'int *', but argument 3 has type 'enum xenbus_state *' [-Werror=format=]
if(sscanf(value, "%d", &readst) != 1) {
^
cc1: all warnings being treated as errors
原因：gcc4.8.2对C99语法支持不好
解决方案：将系统默认的GCC 降级到4.7
具体操作如下：

• 使用apt-get安装特定版本的GCC
  

sudo apt-get install gcc-4.7

• 使用update-alternatives配置版本
  

下述命令将特定版本的GCC 列为GCC  的选项
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 40
下述命令设置选择哪个版本的GCC 作为默认的GCC 
sudo update-alternatives --config gcc

• xl报错
  

# xl info
xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
libxl: error: libxl.c:99:libxl_ctx_alloc: cannot open libxc handle: No such file or directory
cannot init xl context
是因为没有挂载 xenfs 的缘故
挂载一下:
# modprobe xenfs

# mount -t xenfs xenfs /proc/xen

• 启动Domain0
  

# /etc/init.d/xencommons start
