Description Juro Bystricky 2015-04-30 23:39:22 UTC 
Assume recipe contains the following and MACHINE=qemux86-64:

SRC_URI = "file://file1"
SRC_URI_qemux86-64 += "file://file2"
SRC_URI_qemux86-64 += "file://file3"

run bitbake -e 

and observe:
SRC_URI="file://file2 file://file3"

Seemingly identical program: 

SRC_URI = "file://file1"
SRC_URI_append_qemux86-64 = "file://file2"
SRC_URI_append_qemux86-64 = "file://file3"


SRC_URI="file://file1 file://file2file://file3"

So apparently the two syntaxes are not equivalent, and I suspect there is a bug in the first case.

It should say 
<snip>

case 2:
run bitbake -e 

and observe:

SRC_URI="file://file1 file://file2 file://file3"

So apparently the two syntaxes are not equivalent, and I suspect there is a bug in the first case.

If you read the bitbake manual you will see that these are not intended to behave identically. This is how it is defined to behave.

Fair enough, RTFM. I got bitten by this but why blame self when I can blame it on a bug. However, I still think there are some inconsistencies. As I recall, this were the steps I took:

Step 1:

SRC_URI = "file://file1"
SRC_URI += "file://file2"

bitbake -> builds OK

Step 2: "Improve" recipe by adding an override:

SRC_URI = "file://file1"
SRC_URI_qemux86-64 += "file://file2"

bitbake -> builds OK

Step 3:
Final test, same "improved" recipe, clean build (wipe TMP)

bitbake -> error: file1 not found.
