Hi all,

We're in the middle of an upgrade to Thud 2.6.2. While doing so, we
blindly updated all upstream layers we use and we found out (during
integration phase, no need to send lawyers :) ) that even though we have
GPLv3 in INCOMPATIBLE_LICENSE, qt5.11 was built.

LICENSE = "GFDL-1.3 & BSD & ( GPL-3.0 & The-Qt-Company-GPL-Exception-1.0 | The-Qt-Company-Commercial ) & ( GPL-2.0+ | LGPL-3.0 | The-Qt-Company-Commercial )"

My understanding of the above LICENSE is that even though I have GPLv3
blacklisted, because I haven't blacklisted The-Qt-Company-Commercial the
package got built. I'm not really happy with Qt doing that (no warning,
no LICENSE_FLAGS). Quick question unrelated to the actual important

Would it be possible (theoritically, I know you've nothing to do with
maintenance of meta-qt5; also not tested, just "pseudo-code") to have
something like:
python() {
if "GPLv3" in d.getVar('INCOMPATIBLE_LICENSE'):
d.setVar("LICENSE_FLAGS", "commercial")

so if we are blacklisting GPLv3, we have to add commercial_qtbase to
LICENSE_FLAGS_WHITELIST to be able to build it.

So now, the actual issue. I've blacklisted The-Qt-Company-Commercial as
well and qtbase is still building. How so?

For me, it results in the following:
LICENSE = "GFDL-1.3 & BSD & ( not-compat & The-Qt-Company-GPL-Exception-1.0 | not-compat ) & ( GPL-2.0+ | LGPL-3.0 | not-compat )"
which in the end looks like:
LICENSE = "GFDL-1.3 & BSD & not-compat & ( GPL-2.0+ | LGPL-3.0 | not-compat )"
which is basically:
LICENSE = "not-compat"

Is there an error in this simplification?
Am I misunderstanding how INCOMPATIBLE_LICENSE is working in Yocto?
Have I missed something?
Is there something actually buggy in the INCOMPATIBLE_LICENSE

Also, please note that I tested with GPL-3.0 in INCOMPATIBLE_LICENSE as
I wanted to exclude license "aliases" not being supported by
INCOMPATIBLE_LICENSE (and since it's what's apparently tested from what
is said in the mega-manual).

I want to be sure to not be able to build qt >= 5.7, we're never too far
from an unfortunate upgrade or people in the company not knowing we
cannot use qt >= 5.7.
