1、环境

ubuntu12.04

arm-linux-gcc  4.6.2

dbus1.0.2

2、配置

参考yanzi1225627的博客 http://blog.csdn.net/yanzi1225627/article/details/7855124 

./configure --host=arm-linux --prefix=/usr/local/dbus-1.0.2-arm CC=arm-linux-gcc --cache-file=arm-linux.cache --without-x

2.1 报错：configure: error: cannot run test program while cross compiling

输入：sudo echo ac_cv_have_abstract_sockets=yes>arm-linux.cache

2.2 报错：checking for libxml-2.0 >= 2.6.0... configure: error: No XML library found, check config.log for failed attempts

缺少libxml2的库，那就安装吧,  输入 sudo apt-get install libxml2-dev

再次配置，成功

3、编译

make

出错：

dbus-sysdeps-unix.c:996:18: error: storage size of 'cr' isn't known

打开该文件，加入ucred的定义

<pre name="code" class="objc">struct ucred
{
pid_t pid; /* PID of sending process. */
uid_t uid; /* UID of sending process. */
gid_t gid; /* GID of sending process. */
};

若出错：......./arm-fsl-linux-gnueabi/bin/ld: cannot find -lxml2

可能是因为刚才使用apt-get安装的是ubuntu上的libxml2，虽然配置通过来，但现在需要的是arm版本的dbus，必然是需要链接arm版本的libxml2，所以还是重新交叉编译一个xml2好了。

下载libxml2

http://download.chinaunix.net/download.php?id=35177&ResourceID=6095

解压，进入目录，同样是configure => make => make install的安装方式

参考configure -help配置安装路径，编译器，安装环境

<span style="font-size:18px;">czw@ubuntu:/usr/local/libxml2-2.7.8-arm/lib$ ./configure --prefix /usr/local/libxml2-2.7.8-arm --host arm-linux CC=arm-linux-gcc
</span>

这个安装好顺利

xml2安装完成，设置环境链接环境变量

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/libxml2-2.7.8-arm/lib

或者再配置时加入CFLAGS=”-L/usr/local/libxml2-2.7.8-arm/lib“

继续make

成功

4、安装

make install

5、dbus1.2.4的安装

config-loader-libxml.c:26:30: fatal error: libxml/xmlreader.h: No such file or directory
compilation terminated.

./configure --host=arm-linux --prefix=/usr/local/dbus-1.2.4-arm CC=arm-linux-gcc --cache-file=arm-linux.cache --without-x --x-includes=/usr/local/libxml2-2.7.8-arm/include/libxml2

还有错误。。。待解决
