在Qt2.2.0下使用多线程的问题 [复制链接]

我用友善之臂的mini2440开发板写一个Qt应用程序，使用多线程编译出现问题如下：
main.cpp:462: error: invalid conversion from 'void*' to 'void* (*)(void*)'
main.cpp:462: error:   initializing argument 3 of 'int pthread_create(pthread_t*, const pthread_attr_t*, void* (*)(void*), void*)'
请问如何解决？
我的源代码在附件中。我是这样编译的：
./build
我的hello.pro 文件应该如何配置才能使用系统库函数？
