oelint.vars.srcuriappend

severity: error

Example

In any bitbake recipe

SRC_URI += "file://abc"
inherit def

Why is this bad?

If the inherit class uses SRC_URI ?= "file://ghi" the setting would be ignored, a weak variable default only become effective if there's no previous value.

Depending on what should be done the SRC_URI operation in the recipe should a hard assignment SRC_URI = "file://abc" to override the default choices of the inherit class.

Or if it should be an append it needs to be SRC_URI:append = " file://abc"

This check only will raise issues, if all of the requested inherit classes, can be found in the same layer.

Ways to fix it

To override any default value use

SRC_URI = "file://abc"
inherit def

or to append use

SRC_URI:append = " file://abc"
inherit def

if you can fix the original class that creates the weak define, by using a small hack like

WEAK_DEF ?= "file://abc"
SRC_URI:prepend = "${WEAK_DEF} "
