Yocto Build imx.6 Qt5 Build Error due to Ubuntu 18.04 System headers

[alptugcalik]

I have setup the Yocto Project and built successfully a Linux image for my board. It works properly for simple applications. However, for some of my applications , the toolchain crashes. The header files in the toolchain tries to reach the headers in my ubuntu 18.04 system files. How can i solve this?

Hello,

Thanks for your reply. I have found out that a variable IMX_SYSROOT is used in some of the project files in Qt5. By adding this variable to project environment variables, i solved the problem. I specifically point the directory where I build the SDK of the imx6 board.

Hello Alptugcalik,

How the application is crashing? the yocto run fine? then you have an issue with the application that is not supported by yocto.

Regards
