您好：我看过这个帖子，把交叉平台-xplatform配置成linux-g++的话，这样是x86架构的吧，工具链使用的是arm-linux-gnueabihf-，这样编译就出错了：

我在ubuntu上可以使用webengine模块，只是想移植到开发板上，使用交叉工具链编译的qmake编译的时候提示找不到模块，就是libwebengine库没有生成，进入到qtwebengine模块内部，没有lib文件夹和mkspces文件夹，但是主目录下的Makefile已经生成，qtwebengine已经被选中编译了。

如果是要改成linux-g++的话，是不是qmake.conf中的工具链要直接指定成gcc g++，那这样的话在arm板上就用不了了。
