I suggest adding a new entry to the end of '3.2.1. Conditional Metadata': * Setting a variable for a single task: BitBake supports setting a variable just for the duration of a single task. Here is an example: FOO_task-configure = "val 1" FOO_task-compile = "val 2" In this example, FOO will have the value "val 1" while the do_configure task is executed, and the value "val 2" while the do_compile task is executed. Internally, this is implemented by prepending e.g. "task-compile:" to the value of OVERRIDES for the local datastore of the do_compile task. This syntax can also be combined with e.g. "_prepend", as in the following example: EXTRA_OEMAKE_prepend_task-compile = "${PARALLEL_MAKE} " Cheers, Ulf 64953 1 srifenbark 2016-08-08 16:40:31 +0000 Ulf, See http://www.yoctoproject.org/docs/2.2/bitbake-user-manual/bitbake-user-manual.html#conditional-metadata for the new item in that list.

Look at this version - http://www.yoctoproject.org/docs/2.2/bitbake-user-manual/bitbake-user-manual.html#conditional-metadata. I didn't like the way it originally read.

I agree that "this syntax can also be combined with for example..." sounds a bit sloppy. :) Cheers, Ulf 65312 5 bluelightning 2016-08-18 15:59:42 +0000 Great, I was just about to file this. One note to make is that if the task name contains underscores then they need to be replaced with hyphens when specifying the override e.g. VARNAME_task-populate-sysroot = "somevalue" 67558 6 srifenbark 2016-10-25 20:12:03 +0000 Moving to 2.3 M2 71474 7 srifenbark 2017-03-20 18:19:07 +0000 Setting to 2.3 M4. Paul - See http://www.yoctoproject.org/docs/2.3/bitbake-user-manual/bitbake-user-manual.html#conditional-metadata and the "Setting a Variable for a Single Task" item in the list. I added a new note. Tell me if this is okay. Thanks, Scott 72228 8 srifenbark 2017-04-10 18:17:22 +0000 Hi, No review since March 20th... assuming okay. Setting to RESOLVED and marking the doc flag "done." Scott
