For example, I wanted to prevent the execution of the real do_build, so I created an empty one: python do_build () { } This apparently simple trick didn't work, I got the error: " ... Failure expanding variable do_build: IndexError: string index out of range" changing the method to: python do_build () { # gibberish } did the trick. The limitation imposed seems unnecessary. Btw, I still didn't get any line number for the error, which tends to be annoying. 51974 1 richard.purdie 2015-06-27 21:53:39 +0000 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=dcbbe545bf5dbd34c8e2f934a33e59e5d38843cc 59070 2 daniel.alexandrux.istrate 2016-02-16 09:02:30 +0000 Verified on master: 36b43b233c841b3c09fc17e04686b4b758780963 Steps: 1. git checkout 43c6e8c0dd7a7139b476b94d69a0252c639393bf 2.
