【提问】在QTE2.3.x用qextserialport串口类应作怎样的修改? [复制链接]

我在QT3上编译下载的qextserialport没问题 ,但在QTE2.3.10下编译就出现如下错误:
qextserialbase.h:174: ISO C++ forbids declaration of `Offset' with no type

/qt_tool/qte-host-2.3.10/include/qiodevice.h:128:     virtual int

make: *** [mainwindow.o] Error 1

试着修改qiodevice.h 的内容把unit int 前的virtual去掉这些错误都没有了 ,但是其它的库可能调用了
qiodevice 又有其它的错误 ,那为知道怎么修改 ,请指点一下 .

编译通过了 !

楼主顺便贴下怎么处理的啊
可以参考下嘛

修改后只是在QTE2.3.10编译通过 ,但不能保证 使用时不出错呀.

我怎么才能上传 ?贴出来太多了

贴出来看看啊。

那位说一下，我也编译不了

顶，说一下，我也遇到这样的问题

Q_LONG的数据类型编译器不认识，可以跟进到源码里面把数据类型改成linux对应的标准类型，我是这么做的，可以用。
