如何编译支持文本编解码器的 Qt 库 4.7.1？
我已经成功构建了静态Qt库，我可以看到plugins/codecs/libqcncodecs.a，但我仍然无法像这样使用GB18030：
QTextCodec::codecForName("GB18030")
而且我仍然找不到中文相关的编解码器，
foreach (int mib, QTextCodec::availableMibs()) {
QTextCodec *codec = QTextCodec::codecForMib(mib);
QString sortKey = codec->name().toUpper();
qDebug()<<sortKey;
}
这就是我的应用程序的输出：
"SYSTEM"
"UTF-8"
"ISO-8859-1"
"ISO-8859-15"
"UTF-32LE"
"UTF-32BE"

如何添加中文文本编解码器？
I've successfully built static Qt library and I could see plugins/codecs/libqcncodecs.a, but I still can not use GB18030 like this:
QTextCodec::codecForName("GB18030")
and all I still couldn't find Chinese related codecs by
foreach (int mib, QTextCodec::availableMibs()) {
QTextCodec *codec = QTextCodec::codecForMib(mib);
QString sortKey = codec->name().toUpper();
qDebug()<<sortKey;
}
That's the output of my app:
"SYSTEM"

文档说：“要静态链接这些插件，您需要在您的应用程序中使用 Q_IMPORT_PLUGIN() 宏，并且您需要使用 QTPLUGIN 将所需的插件添加到您的构建中。”
我认为您的应用程序中缺少
Q_IMPORT_PLUGIN(qcncodecs)。The documentation says: "To link statically against those plugins, you need to use the Q_IMPORT_PLUGIN() macro in your application and you need to add the required plugins to your build using QTPLUGIN."
I think you are missing a
Q_IMPORT_PLUGIN(qcncodecs)in your application.
