内容:
如题，桌面FC4，tmake-1.13 , qtx112.3.2 ,qte 2.3.10 ,arm-linux-gcc 3.4.1
qte编译成PC和ARM两个版本。PC版根据qte2.3.10里的安装手册编译，ARM版根据网友断水刀的方法编译（见附录二）。同样出现下面的错误，
问题一：请问大家这是什么原因？会对生成的库有影响吗？
我使用附录一所示的小程序进行测试，在QVFB运行正确，在ARM版的qte上编译也正常。可是把程序传到开发板上运行出现segmentation fault。我是把ARM版qte下生成的lib和arm的库文件发到我的文件系统中。运行程序前指定export LD_LIBRARY_PATH=/lib;(开发板上库文件)。我第一次移植qte，希望大家指点一下，是否我还需要在文件系统中加入什么东东？谢谢
附录：
一 小程序
#include
#include
int main(int argc, char **argv)
{
QApplication app (argc, argv);
QLabel *hello = new QLabel("HelloQt/Embedded! ", 0);
app.setMainWidget(hello);
hello->show();
return app.exec();
}
二 Qt/E 的交叉编译
要将我们写好的程序发布到开发板上，我们需要对Qt/Embedded 重新编译，与前面在宿主机上编译类似，步骤如下：
1． Build Qt/Embedded
tar –xzvf qt-embedded-2.3.10-free.tar.gz
mv qt-2.3.10 qt-2.3.10-target
export TMAKEDIR=$PWD/tmake-1.13
export QT2DIR=$PWD/qt-2.3.2
export QTEDIR=$PWD/qt-2.3.10-target
cd $QTEDIR
export TMAKEPATH=$TMAKEDIR/lib/qws/linux-arm-g++
export QTDIR=$QTEDIR
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
make clean
./configure -xplatform linux-arm-g++ -no-xft -no-qvfb -depths 4,8,16,32
make
出现

没有做过，期待高手~~~

Please check your version of uclibc on
1) /usr/local/arm/lib
2) /target/lib
It may due to different version.

你的QTE并没有编译成功，链接时没有链接到正确的libc或ulibc库上，检查一下
