Bitbake bbappend file percent in filename

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"?

Solution

  • 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.
