Hello everyone, I am the only guy on earth that still uses UDOO Neo. I am trying to build a Yocto image (because URL's of ready images are 3 years old and broken of course). I am just trying to execute my QT application on a UDOO Neo for FOUR WEEKS (sounds easy, I know right?). Every attempt I made, faces me with some errors. And I am always giving up. Now I decided to build a Yocto image with QT5 goods for myself and run my application on fifth week. Guess what? There is an error. Did everything just like how it is done in https://github.com/graugans/meta-udoo/wiki/Getting-started. (host system is Ubuntu 18.04 LTS) When I run in the end, Code: $ MACHINE=udooneo bitbake udoo-image-qt5 Code: ----------Output------------- [some installation text.. I will directly skip to the summary.] NOTE: Tasks Summary: Attempted 90 tasks of which 0 didn't need to be rerun and 1 failed. Waiting for 0 running tasks to finish: Summary: 1 task failed: /home/closx/bin/udoo-community-bsp/sources/poky/meta/recipes-devtools/m4/m4-native_1.4.17.bb, do_compile Summary: There were 6 WARNING messages shown. Summary: There were 2 ERROR messages shown, returning a non-zero exit code. GUYS PLEASE HELP ME ANYONE FOR MY MENTAL STATE
