linux下opencv2.0编译问题

  我在fedora11中装好了qt和qtcreator（这个肯定能用的），后来又装了opencv2.0（一路的./configure make make install都没有问题）。
  但是我在qtcreator中编译时，会报错：C/C++ code

/data/release/pictureviewer.cpp:23: 错误：expected initializer before ‘*’ token
/data/release/pictureviewer.cpp: In member function ‘void Dialog::openCAM()’:
/data/release/pictureviewer.cpp:239: 错误：‘cascade’在此作用域中尚未声明

我就很郁闷，因为我已经把libcv.so等opencv的库都放到了/usr/lib里面了，而且也修改了/etc/ld.so.conf
还根据网上的教程，把qmake.conf和*.pro里面添加了INCLUDEPATH等内容···还是不行···希望各位帮帮忙，因为我为这个问题搞了很久了。

???版主帮帮忙吧···
