Thanks, all. I wanted to share the solution. This vendor-supplied version of yocto looks like 2.0, so the space separated expressions are not available. After putting some print statements in cooker.py I discovered that appending to BBMASK in conf/bblayers.conf or conf/local.conf has no effect. It was not until I modified BBMASK_forcevariable in my conf/bblayers.conf that I saw any change in behavior.
BBMASK_forcevariable = ".*openjre|.*openjdk|.*qemu_qoriq" This inability to modify BBMASK unless using _forcevariable was also noted last year. https://lists.yoctoproject.org/pipermail/yocto/2016-September/032033.html -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
