yocto - Bitbake bbappend 文件名中的文件百分比

Question

我在 yocto 文档中找不到为什么某些 bbappend 文件的文件名中有“%”。一个例子是“qtbase_%.bbappend”。

这是否意味着“适用于所有版本的 qtbase bitable recipe”？

Answer 1

%接受通配符以匹配任何字符。例如
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.
