这个是咋解决的，我看到库文件里面有libQtGui.so。不知道为什么不成功

不妨仔细看看那句话。是谁没被找到。

我也知道是谁没找到。但怎么解决啊？

求指点啊。我用的QT4.8也是这个问题。不知道如何解决……

没有遇到过，坐等答案

求解决办法啊！……

自己去Makefile里指定libQtGui.so的所在。

换了个低版本的交叉编译器又出现了
/usr/local/Trolltech/QtEmbedded-4.7.0-arm/lib/libQtCore.so: undefined reference to `inotify_init1@GLIBC_2.9'
/usr/local/Trolltech/QtEmbedded-4.7.0-arm/lib/libQtGui.so: undefined reference to `pipe2@GLIBC_2.9'

是这个libpng.so.3没找到？？？
