So after several attempts, the issue is not solved yet but I succeeded into compiling legato tools by using this command : **repo init -u [GitHub - legatoproject/manifest: repo manifests for Legato](https://github.com/legatoproject/manifest)** (I think by not specifying the version of legato it will download the latest one) After that I built legato with make wp77xx (my version of magnOH) For the next step, I did : **make red\_wp77xx** in the my mangOH directory but the following error popped up : > echo “Not building LEGATO due to $LEGATO == 0” > Not building LEGATO due to $LEGATO == 0 > > # NOTE: When using leaf, these TOOLCHAIN\_X variables don’t need to be passed to mksys. > > TOOLCHAIN\_DIR=/opt/swi/SWI9X06Y\_02.22.12.00/sysroots/x86\_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi > TOOLCHAIN\_PREFIX=arm-poky-linux-gnueabi- > mksys -t wp77xx --object-dir=build/red\_wp77xx --output-dir=build/update\_files red.sdef > \*\* ERROR: > /home/insa/mangOH/apps/RedSensorToCloud/redSensorToCloud.adef:30:4: error: Binding to non-existent server app ‘avcService’. > Makefile:109: recipe for target ‘red\_wp77xx’ failed > make: \*\*\* [red\_wp77xx] Error 1 the error still persists even after I followed your suggestions : [Make red\_wp85, return ERROR - #9 by Alex](https://mangoh.discourse.group/t/make-red-wp85-return-error/1175/9) Hope you can bring me an anwser --- _[View the full topic](https://mangoh.discourse.group/t/cross-compiler-error/2801)._
