However, With Dylan and later, running the suggested command gives the same error instead of opening a development terminal. To see this in practice, you will need to break a machine by modifying an .scc file such that another included .scc file is not found. The file not found causes the do_patch to fail, which prints the "Patch failures can be resolved in the devshell (bitbak -c devshell ${PN})" However, since devshell runs after do_patch, and do_patch fails, there is no way into the devshell. This bug is not to report a broken do_patch (it should have been broken), but is to report the invalid help message printed when an error does occur. 42973 1 bluelightning 2014-04-24 14:49:00 +0000 devshell.bbclass sets do_devshell to run after do_patch, so it seems that a broken patch could block devshell from executing for any recipe, not just the kernel. We could change devshell to be run after do_unpack instead, but then that would break some people's workflow if they expect to start with the patched source as they do currently. We do have another option here - we have a proper shell-based interactive patch resolution feature that is enabled by setting PATCHRESOLVE to "user". Since kernel-yocto.bbclass has its own custom do_patch it may not currenly work with this however; perhaps the best solution would be to make it work with that if it doesn't and change the message (which is specific to kernel-yocto.bbclass) to recommend using that rather than devshell which won't work anyway. 48697 2 bruce.ashfield 2015-02-10 21:11:06 +0000 For now, we'll get the message update and worry about changing the devshell dependencies in 1.9. Changing the status to "in design".
