yocto building qt tools that do not run on imx8

[terry1]

Programs that are SYSV will run, Exec format error if GNU/Linux

When will yocto be fixed?

/usr/bin/qt5/.debug$ ./qmake
-bash: ./qmake: cannot execute binary file: Exec format error

My qttest program built on the imx8 works

which BSP are you using?

[terry1]

From the Yocto Project user guild rev l4.14.78-1.0.0. Does this answer your question?

$ mkdir imx-yocto-bsp
$ cd imx-yocto-bsp
$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m
imx-4.14.78-1.0.0_ga.xml
$ repo sync

Although this is for i.MX6ul, you may take this for reference.
