This is an example of the new error message after the patch: ``` runqemu - ERROR - In order for this script to dynamically infer paths kernels or filesystem images, you either need bitbake in your PATH or to source oe-init-build-env before running this script. Dynamic path inference can be avoided by passing a *.qemuboot.conf to runqemu, i.e. `runqemu /path/to/my-image-name.qemuboot.conf` Bitbake is needed to run 'bitbake -e', but it is not found in PATH. Please source the bitbake build environment. ``` CC: Richard Purdie CC: Alexander Kanavin Signed-off-by: Richard Grünert --- changes in v4: Changed commit message and error message string according to suggestions by Alexander Kanavin. changes in v3: Messed up the CC tag :) changes in v2: Changed the position according to suggestion by Alexander Kanavin.
