Anything supported by your *board* *vendor* is supported.

Is your board vendor providing security fixes for that 3.14? If not, use the 
one they are providing support for.

If they are not providing support for any kernel on that board, then you've 
got a doorstop. Use it as a doorstop and get another board.

ICU should always be used in the latest version since it contains data that 
changes every year, some of them multiple times a year, like the timezone 
database.

That also means you need to design your system so it'll get updates.

Re: [Interest] Qt Creator licensing for companies with Qt Commercial developers

2020-03-30 Thread Tuukka Turunen 

Hi,

That is not the question that was originally asked.

The question was about some developers using commercially licensed “Qt for 
Application Development” product and other developers using Qt Creator under 
open-source license. This is not allowed, because the license agreement of Qt 
for Application Development does not allow use of open-source versions of its 
contents in the same project (and Qt Creator is part of Qt for Application 
Development).

Yours,

Tuukka

The only difference that comes to mind is that the first group can use
Qt Creator under its commercial license, which may come with some extra
features (not exactly sure of which ones, at this particular point in time).

The second group can instead just use Qt Creator under its open source
license. The open source license of Qt Creator itself does NOT extend in
any way to the software you develop (cf. the GPL FAQ).

Hi,

Please read the commercial license agreement and the licensing FAQ. The 
restriction has nothing to do with open-source licensing. It is about a 
company, who is using a commercially licensed Qt not to use parts of the same

What about open-source versions provided by another distributor, e.g. someone 
doing apt install qtcreator ?

Also how is that compatible with this part of the Qt Creator license  ?

2020-03-30 Thread Andy 
That makes no sense. Your license prevents a company from using an
open-source tool? It says "if you license our stuff you cannot use the
open-source tool X"?

This whole thread is yet another great example of where the Qt Company is
totally tone-deaf.

Nobody understands your licensing. You have fewer people using Qt and
Qt-based things because of this.

I do understand that it can feel off to have such a restriction for using "Qt

these are included in the Qt for Application Development product. So both need 
to be used with same type of license: open-source or commercial.

OK, Here goes the explanations of how to interoperate with Qt Software 
packages. IANAL. We will start from the easy and work our way towards difficult.

QtCreator: QtCreator is free. You, as a developer of software, can use 
QtCreator as your IDE to develop your own software. The GPL license of 
QtCreator will NOT infect your software. Use QtCreator to create open or closed 
software. Free or commercial. Your choice.

QtCreator as Part of a Commercial Qt License: The only thing this gets you 
is the ability to get some "commercial" support versus just posting on the 
qt-creator mailing list.

Modifying QtCreator: If you are actually modifying QtCreator yourself to 
create a distribution outside of your organization then ANY codes you write or 
modify are subject to the QtCreator license. This has ramifications if you 
happen to have a Qt commercial license.

Using Qt5 in your software project: If you use Qt in your project ANYBODY 
contributing to that same project MUST have the same kind of Qt license. 
Period. Full Stop.

For the original question;
"Is it still possible for the developers who don't use Qt libraries in
any way, use Qt Creator IDE for editing and debugging?"

The answer is YES, but the devil is in the details. They *should* be able 
to just download the free version of QtCreator from http://download.qt.io and 
use that version. They can't use the "commercial" version of QtCreator unless 
they have a commercial license for Qt. But if their projects are *not* using 
Qt, then why do they have a commercial license for Qt?


Again, IANAL, but I believe this to be a reasonable summary of the 
licensing of QtCreator and Qt.

the problem is, as already stated, that some did not answer your 
question properly.
i understood your question. and as i said, your mixing up things. as we 
say: you mix apples and pears.

you're talking about using an executable X, based on open source 
software.
you're talking about using an library Y, for which you have a license, 
based on open source software, too.
you're talking about using exec X to use Y somehow.
you're talking about using exec X with other libraries.

now what has tool X todo with library Y? nothing.
well, it happen to be that tool X is written using library Y, but thats 
of no concern here.

the licese for Y only clearifies how you may use/include the library Y 
into your projects, 
and not how to use tool X to build apps using library Y.



other words:
would you ask if you have to use the commercial vs license because you 
bought a qt license?

Re: [Interest] Qt Creator licensing for companies with Qt Commercial developers

2020-03-30 Thread Tuukka Turunen 

Hi Andy,

I know that the dual licensing can be confusing. To defend it a bit: it gets 
confusing mainly when the question is about mixing the license types. It is 
simple and straightforward when a company uses commercial license and asks also 
possible contractors (working in the same project) to use commercial. Similarly 
it is simple when all use the open-source version.

If you want to understand the topic better, please read the commercial license 
agreement and the licensing FAQ. The restriction has nothing to do with 
open-source licensing. It is about a company, who is using a commercially 
licensed Qt not to use parts of the same licensed Qt product under open-source 
license. If there was no such restriction, a company could have a team of 10 
developers, but only 1 or 2 commercial license for Qt.

I do understand that it can feel off to have such a restriction for using "Qt

Re: [Interest] Qt Creator licensing for companies with Qt Commercial developers

2020-03-30 Thread Juergen Bocklage-Ryannel 
Hi,

I guess the conflicting terms are these:

“Prohibited Combination” shall mean any means to (i) use, combine, incorporate, 
link or integrate Licensed Software with any software created with or 
incorporating Open Source Qt, (ii) use Licensed Software for creation of any 
software created with or incorporating Open Source Qt, or (iii) incorporate or 
integrate Applications into a hardware device or product other than a Device."

Especially this combination: “use … Licensed Software with any software created 
with … Open Source Qt”

KDE, doxygen, Wireshark (just to name a few) are using Open Source Qt. 

Can someone reflect how does it apply to that software? Can a customer use them 
to create software under the Qt commercial License terms?

I understand the wishes of Qt Company. Business wise these make sense, still 
there might be a conflict with other Licenses (especially Qt Creator Open 
Source). I am unsure if the Qt Commercial License is in direct conflict with 
(L)GPL license. But I guess someone has thought this through.

Best regards
/ jryannel

I am not a lawyer and any opinion towards Licensing is my personal very 
subjective opinion.

Up until now, you've said "same project". Now you are switching to
"company". Please clarify.

I'm assuming it is "project", since that's what the FAQ says.

If it is "project", please clarify what definition of project is used.

Re: [Interest] Qt Creator licensing for companies with Qt Commercial developers

2020-03-30 Thread Michael Jackson 
Dear Tuukka,
   Let us take a concrete example of a hypothetical company. The company has 10 
software engineers and 2 projects.

Engineers 1,2,3,4,5 work on proprietary project A that uses Qt commercial 
license. Each engineer (1,2,3,4,5) has a commercial Qt license assigned to that 
engineer. They use QtCreator from the commercial package to develop such a 
software. The proprietary software being developed is for a Desktop application 
and uses Qt5 as part of its development.

Now, Engineers 6,7,8,9,10 all work on an open source project B that does not 
use Qt libraries at all. Those engineers (6,7,8,9,10) all really like QtCreator 
and want to use it to develop that open source library. I, as the company 
owner, instruct those engineers to download the open source version of 
QtCreator and use that open source version of QtCreator to develop their open 
source software.

There is *no* cross over between the 2 engineering groups.

Is this situation allowed by the Qt Commercial license? If it is *not* allowed 
consider me a lost supporter of Qt anything.

Hi Michael,

Please read the commercial license agreement and the licensing FAQ. The 
restriction has nothing to do with open-source licensing. It is about a 
company, who is using a commercially licensed Qt not to use parts of the same 
licensed Qt product under open-source license. If there was no such 
restriction, a company could have a team of 10 developers, but only 1 or 2 
commercial license for Qt.

I do understand that it can feel off to have such a restriction for using 
"Qt Creator" when others are using "Qt libraries". The important point is that 
both these are included in the Qt for Application Development product. So both 
need to be used with same type of license: open-source or commercial. 
 
Yours,
 
Tuukka

OK, Here goes the explanations of how to interoperate with Qt Software 
packages. IANAL. We will start from the easy and work our way towards difficult.

QtCreator: QtCreator is free. You, as a developer of software, can use 
QtCreator as your IDE to develop your own software. The GPL license of 
QtCreator will NOT infect your software. Use QtCreator to create open or closed 
software. Free or commercial. Your choice.

QtCreator as Part of a Commercial Qt License: The only thing this gets 
you is the ability to get some "commercial" support versus just posting on the 
qt-creator mailing list.

Modifying QtCreator: If you are actually modifying QtCreator yourself 
to create a distribution outside of your organization then ANY codes you write 
or modify are subject to the QtCreator license. This has ramifications if you 
happen to have a Qt commercial license.

Using Qt5 in your software project: If you use Qt in your project 
ANYBODY contributing to that same project MUST have the same kind of Qt 
license. Period. Full Stop.

For the original question;
"Is it still possible for the developers who don't use Qt libraries in
any way, use Qt Creator IDE for editing and debugging?"

The answer is YES, but the devil is in the details. They *should* be 
able to just download the free version of QtCreator from http://download.qt.io 
and use that version. They can't use the "commercial" version of QtCreator 
unless they have a commercial license for Qt. But if their projects are *not* 
using Qt, then why do they have a commercial license for Qt?


Again, IANAL, but I believe this to be a reasonable summary of the 
licensing of QtCreator and Qt.

...and what, pray tell, is the point of leaving the old archives in a
half-broken state? I would either fix them, at least as far as being

I think it has been mentioned before -- to avoid overloading the mirrors 
with a lot of relatively low traffic data. I don't know how the 
mirroring works, so I don't know even _if_ there is another setup that 
would work...
