你换系统倒是很快啊。

写的不标准。 我们的qt版本有差异吧， 可以修正一下。 HOHO

你找到这行：
evamain.cpp:1855: error: no matching function for call to `QString::QString(const std::basic_string<char, std::char_traits<char>, std::allocator<char> >&)'

把出问题的 QString(xxxx)（看起来应该是这个样子的， 没看代码，不确定） 构造函数的 xxxx（std::string 类型的变量） 后面加个".c_str()" 就应该ok了。 结果成为这个样子
QString(xxxx.c_str())

jozhu

你的第1855行的内容是：
mainWin->updateNick(id, codec->toUnicode(QString(frd->getNick())));

照你说的，我看加哪都不太合适啊。老兄你再看看

就改这行
[code:1]
mainWin->updateNick(id, codec->toUnicode(QString(frd->getNick().c_str())));
[/code:1]

少说，多干！
