[yocto] Trying to filter out 2 strings from EXTRA_OECONF, why doesn't this work?

[Ola x Nilsson]

This is not a typical use of variables in bitbake.  I'm not sure whether it is defined behavior or not, but I doubt you'll find many such examples in the yocto layers.

You can write

EXTRA_OECONF_remove = "--with-term=rxvt --with-name=rxvt"

in your bbappend file.  

The problem with this style is that you can never add these options again using _append or any of the += operators.

I ended up completely overriding EXTRA_OECONF in my .bbappend with the configure flags that I wanted.

I guess I don't understand the order of evaluation in yocto's .bbappend and .bb files. Based on the error I got, problem with double use of  := operator, it seems that statements in .bbappend files are not evaluated in order.

The best way to fix this is to modify the original recipe so that all
three options become PACKAGECONFIG-configurable, and submit the patch to
whoever maintains the recipe.
