I have added the DEPENDS line and it indeed downloads and build the some protobuf related stuff, where did you get the dependency name from ? I can't see the protobuf-native as a recipe in the meta-oe website : https://layers.openembedded.org/layerindex/branch/master/layer/meta-oe/ I have just realised that GRPC (http://www.grpc.io/) is needed for my project, it is a library which uses the protobuffers, is there a recipe/package which provides them around or do I need to create my own recipe ? I would like to check the root filesystem being generated as part of the build process, where is it ? -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
