如何解决构建Android的Qt 5.15应用程序的多链接错误 参考文献：

应用程序使用 Qt 5.12.9 （适用于Android）构建良好。但是在链接阶段以 5.15.1 失败（由于已弃用的Qt API已修复，因此可以正常编译）。仅针对arm64-v8a ABI构建：

qmake ANDROID_ABIS="arm64-v8a" ...

具有这样的多个链接错误：

~/Qt/5.15.1/android/include/QtCore/qobjectdefs_impl.h:415: undefined reference to `operator delete(void*)'
obj/QGCMapEngine.o: In function `QList<QString>::append(QString const&)':
~/Qt/5.15.1/android/include/QtCore/qlist.h:626: undefined reference to `__cxa_begin_catch'
~/Qt/5.15.1/android/include/QtCore/qlist.h:628: undefined reference to `__cxa_rethrow'
~/Qt/5.15.1/android/include/QtCore/qlist.h:629: undefined reference to `__cxa_end_catch'
~/Qt/5.15.1/android/include/QtCore/qlist.h:644: undefined reference to `__cxa_begin_catch'

~/Qt/5.15.1/android/include/QtCore/qlist.h:647: undefined reference to `__cxa_end_catch'

尝试修复AndroidManifest.xml，如此处所述：Qt for Android known issues，但没有运气。通过安装最新的Qt SDK和从docker中的源构建的Qt可重现。任何想法是什么问题以及如何解决？

解决方法

问题在以下行的Access to XMLHttpRequest at 'https://75hkwcgiy.execute-api.us-east-1.amazonaws.com/Prod/plans/35580' from origin 'http://[mydomain].com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. GET https://75hkwcgiy.execute-api.us-east-1.amazonaws.com/Prod/plans/35580 net::ERR_FAILED 中进行了修复：QGCCommon.pri#L60

-nostdlib++

对于 5.15 ，需要将其删除并修补QMAKE_LINK += -nostdlib++ # Hack fix 以正确构建APK。在当前Qt Creator安装并默认使用 ndk21 的情况下， 5.12 和was ndk20 problem的该行都可以删除。
