1. tar xvfz qt-2.3.10.tar.gz
2.
QTDIR=/home/qt-2.3.10
LD_LIBRARY_PATH=$QTDIR/libLD_LIBRARY_PATH
PATH=$QTDIR/binPATH
export QTDIR LDLIBRARY_PATH
3. ./configure -xplatform linux-arm-g++ -shared
注意配置时 -shared前有个空格的，否则配置出错。
输入yes,5,16,no
4. make
5. 后来更换高版本的编译器后 连接例子时提示未定义的 __cxa_pure_virtual函数，解决方法是
改变该例子的Makefile里的arm-linux-gcc为 arm-linux-g++即可。
出错误后:
vim src/allmoc.cpp 加入下面的函数。
extern 'C' void
__cxa_pure_virtual(void)
{
//CYG_FAIL('attempt to use a virtual function before object has been constructed');
for(;;);
}
void* operator new[](size_t size)
{
return malloc(size);
}
void* operator new(size_t size)
{
return malloc(size);
}
void operator delete[](void* p)
{
free(p);
}
void operator delete[](void* p, size_t size)
{
free(p);
}
void operator delete(void* p)
{
free(p);
}
void operator delete(void* p, size_t size)
{
free(p);
}
拷贝lib目录到根文件系统就可以测试了。
arm-linux-gcc -v
