Bitbake bbappend file percent in filename

Question

I can't find in the yocto documentation why some bbappend files have a "%" in the filename. An example would the "qtbase_%.bbappend".

Does it mean "apply to all versions of the qtbase bitable recipe"?

The % wildcard is accepted to match any character. For example

PREFERRED_VERSION_linux-imx_mx6 = "3.10.17"

PREFERRED_VERSION_linux-imx_mx6 = "3.10%"

The wildcard is actually allow matching of the name and version up to the point of encountering the %. This approach will allow for matching of the major or major.minor.

Exampes:

busybox_1.21.1.bb

busybox_1.21.%.bbappend will match

busybox_1.2%.bbappend will also match

if we update to busybox_1.3.0.bb the above won't match, but a busybox_1.%.bb will.

Is it possible to specify a wildcard and a specific bbappend in one layer and if so are they prioritized and how? – Phidelux Sep 01 '17 at 10:05
Please create a new question. – Charles C. Sep 01 '17 at 16:10
Is this explanation correct for the filename too? I have file `systemd_%.bbappend`. Is this mean it can apply for all version of `systemd`? – SAMPro Mar 09 '22 at 09:32
% is for file name. And yes, `systemd_%` means all version of systemd – Charles C. Mar 09 '22 at 18:21
