[yocto] Application Development

Fri Jun 7 07:21:10 PDT 2013

When you create your image, what profile did you use.  Are you building one of our existing images, e.g. core-image-minimal, etc. or it's a customized image and if so, how did you customize your image, via layer or install extra packages?  I think x11 is brought in via some package dependency.  You said you were able to build the image, was the x11 packages there?  We're building a toolchain plus the sysroot that matching the rootfs of your target image here so it's not just the toolchain that is built.

Ok. But out of curiosity, why should I need X11 packages for a simple command-line based toolchain?
I assume that none of these X11 packages gets copied to my target device rootfs, or?
