以下代码无法使用g ++编译此错误以及与clang类似的错误.

main.cpp:16:19: error: 'QByteArray' is a private member of 'QByteArray'
        Container2(const QByteArray &ba);
                         ^
main.cpp:3:18: note: constrained by private inheritance here

                 ^~~~~~~~~~~~~~~~~~

main.cpp:18:30: error: 'QByteArray' is a private member of 'QByteArray'

我不明白为什么Container2不允许继承Container1并通过公共构造函数初始化它,即使QByteArray的继承是私有的.

#include <QByteArray>

class Container1:private QByteArray
{
public: 
    Container1() {} …

我刚刚从Opensuse 13.1升级到13.2,并且无法让我的Qt开发让android正常工作.我的调查让我相信它更像是一个Android开发问题(蚂蚁)而不是与Qt有关.

在尝试部署示例项目时,我收到以下错误.我发现它可能与缺少的xml-apis包有关,可能xml-commons包应该提供这个功能,但它们似乎没有.

我对Java并不熟悉,现在已经坚持了一段时间.任何建议赞赏.
