我在ubuntu上用ARM-linux-gcc重新编绎了QT，在Trolltech下生成QtEmbedded-4.8.6-arm目录，添加环境变量后qmake -v
root@ubuntu:/home/shiyu/qtex1# qmake -v
QMake version 2.01a
Using Qt version 4.8.6 in /usr/local/Trolltech/QtEmbedded-4.8.6-arm/lib

使用了新的qmake
然后我写了个hello.cpp用新的qmake编绎，make里就出现了下面的错误，
root@ubuntu:/home/shiyu/qtex1# make

找了好久都没解决方法，那位大神遇到过这个问题啊？ 此帖出自Linux与安卓论坛
