我有一个工作的氮6x板，该板在yocto krogoth-next build build with core core-image-sato上运行。我已经安装了QT Creator 3.5.1（基于QT 5.5.1），并且根据[Build＆amp;安装QT5工具链]文档。我添加了一个示例QT快速应用程序，其中选择了QT Quick 2.1的组件集并尝试编译源，我注意到以下错误。

所有QT库都存在于/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/include/qt5/下，我已经在套件下正确设置了SYSROOT路径，但是我无法弄清楚为什么我的应用程序未能参考这些库。对此的任何帮助将不胜感激。提前致谢。
MKSPEC指向您的套件指向的MKSPEC似乎是错误的（linux-g++），引用了您的构建日志
-I/opt/poky/2.1.1/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/lib/qt5/mkspecs/linux-g++
在为氮6x构建时，可能是linux-oe-g++。默认情况下，在您选择的QT版本中设置，也可以通过修改套件本身（QTCreator的选项）设置，在" Mkspec"下。
您看到的错误可能是由于Abi＆amp;指向的库的架构与您编译的X86/64代码不兼容。
还请确保在启动QTCreator之前启动Yocto的环境文件，如果遇到问题（即找不到有关" C"的错误错误）。这将设置通往交叉补偿器的路径。示例：
source /opt/poky/1.6.2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
