linux2.6.29+qtopia2.2.0 如何实现多线程编程呢？

最近在做qt开发，需要用到多线程编程，不知道目前友善之臂提供的linux2.6.29+qtopia2.2.0能不能实现多线程编程？如何实现？
有做过的大侠指教！！！急

请问怎么解决啊

回答29楼，这个问题我已经解决。把src-mt.mk 里后3项全都注释掉。就能过去。不过我只是编译过去了x86，arm过不去，等待高人解答...

咋个就没人呢，难道问题太弱了？

每一步都按贴子写的，最后 在qt2/目录下执行make src-mt,出现下面的错误：

已解决：将qt2/src/tools/qtextcodec.cpp改成下面的(虽然很简单，可能就是这样大家知道也不说，想了下，贴出来最好了)

细细想来这是很直接的一个问题，折腾这么久，还是因为太害怕错误了，害怕得让人完全失去了分析问题的勇气。
