如何在ubuntu12.04上安装qtopia-2.2.0-friendlyarm (linux strrchr)
1、首先进入管理员状态：sudo su
这时进入管理员状态root@ubuntu:/opt/EmbedSky/Qte#，这个＃代表是管理员。如果是在普通用户下是me@ubuntu:~$ ，是$，在普通用户下也会产生许多问题。
2、进入管理员状余旅岩态后的环境变量和普通用户是不一样的，可以echo $PATH看看。添加arm-linux-gcc的环境变量。export PATH=$PATH:/opt/EmbedSkye/4.3.3/bin
3、可能出现的错误：
首先下面这篇文章给了我极大的提示。
在编译x86-qtopia-2.2.0-konqueror_build时里面提到的两个编译错误都会碰到，当然有可能会碰到库不
全的情况，错误会更多。至于哪些库我也记不清了。这是库已镇桐完全安装的情况下的产生的错误的解决办法。在编译天嵌公司的arm-qtopia-2.2.0-
konqueror_build也会碰到类似的错误。解决方法一样。主要就是要更改qmemoryfile_unix.cpp里面的一个函数的参数。

解决办法：
手动修改x86-qtopia-2.2.0/qtopia/src/libraries/qtopia/qmemoryfile_unix.cpp 141行
将
if (!f)
f = ::open(tmpFile.latin1(), O_CREAT | O_WRON);
修改为
if (!f)
f = ::open(tmpFile.latin1(), O_CREAT | O_WRON, 0666);

解决方法：
修改/x86-qtopia-2.2.0/qtopia/src/libraries/qtopia/backend/vobject.cpp:419行
char *dot = strrchr(g,’.’);
为
char *dot = (char*)strrchr(g,’.’);
4、konqueror的编译
上面是原作者的解决办法。能够成功编译，但是在编译konqueror时就会出现错误 setQpeEnv: not
found。这是无法读取目录下的setQpeEnv脚本所致。首先天嵌的x86-qtopia-2.2.0-konqueror_build也没什么逻
辑上的错误，但是无法读取确实很让人奇怪。
解决办法：在终端的/opt/EmbedSky/Qte/目录下手动执行source ./x86-qtopia-2.2.0/setQpeEnv,再运行 ./x86-qtopia-2.2.0-konqueror_build,就成功编译了。
