License | "or" problem?

License | "or" problem?

[Andrei Gherzan]

As i know qt4 has double license. This means that everybody can choose 
from GPLv3 and LGPLv2.1. This fact is reflected in bb file as:

LICENSE = "LGPLv2.1 | GPLv3"

Well, this "or" operand doesn't work as i end up with this error in a 
GPLv3 incompatible build:

ERROR: Nothing PROVIDES 'qt4-embedded'
ERROR: qt4-embedded was skipped: incompatible with license LGPLv2.1 | GPLv3

You need to explicitly white list qt4-embedded in the 
LGPLv2_WHITELIST_GPLv3, currently the parsing for exclusion just looks 
at the incompatible license.

Also, looking at the current LICENSE in qt, it will need to be further 
defined on a package level as to how each package is licensed, so that 
when the manifest and audit occurs only the LGPLv2.1 bits are included.

We are open to patches such as this.

BTW, we have not tested building a graphical non-GPLv3 image, so you are 
treading on new ground, please let me know how it goes and we might 
include a qt image that is non-GPLv3.

Sau!

Where do you get the idea that there is a mix of licenses for Qt4? As far as I 
am aware, the user is supposed to select either LGPLv2.1 or GPLv3, which is 
exactly what the current value of LICENSE above means.

Cheers,

So if it's like Paul says, this seems to be a bug.
