The beauty of Yocto is that it handles this for you. When you first run Yocto bitbake for a particular MACHINE target it will build a cross-compiler, and associated supporting utilities from source for that target. These are the -native packages that are built. 'Native' in Yocto terminology means "something that run on the build host". It'll then move onto cross-compiling other configured packages for the target, which is all driven by meta-data and meta-data dependencies which are encapsulated in the 'recipes'. My personal experience fwiw is that the easiest way to cross-compile projects to run on the target of your choice is to create an autotools configuration for your project, which then makes it fairly trivial to create a Yocto recipe to cross-compile that project and to package it up into the target image. I have already mentioned this link today, and at the risk of repeating myself I would hope that this walkthrough would show you how to use various flavours of an autotooled project and associated recipe to cross-compile and package your application. https://wiki.yoctoproject.org/wiki/index.php?title=Building_your_own_recipes_from_first_principles The example used is here https://github.com/DynamicDevices/bbexample This is loosely based on the documentation here http://www.niksula.hut.fi/~mkomu/docs/autohowto.html You will of course wish to spend some time with the Yocto Quickstart too I imagine http://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html Regards, Alex -- _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
