Ubuntu amd64下Xen编译错误解决方案

• 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
