[SOLVED] Lisence for open source Qt application?
-
Thank you @mcosta,
-
yes i use "system" command... glad that i dont have to follow their licence...
-
This means that i probably have to test my edition with friends only and not to publish
a beta edition... because this way, it will not last as much as i need to publish my alpha :(
I will think about it a little bit more... maybe another name of my program is not so
bud... but i am afraid that it will not be an opensource...
3)Thank you... this is what i thought too..
Now i have to check only two of the infinitive license i had found... :) -

I am an ubuntu user...
and i chosed ubuntu for their open source philosophy...I want to publish my code and i will do it anyway...
I am just a little bit confused with the licences just because i want
to finish my code before someone take the idea and make a better
program than mine... and sell it instead of offering it as an open source -
Thank you very much @mcosta...
I will finally use the GNU GPLv3...
I know no one can change the license of my program,
i just worry of making his own program on my idea
before my alpha is ready... and sure, this way he could sell it.But it is not a big deal... my program will be finished soon,
and it will be an open source, so i am not afraid,
because open source always are better ;)Thank you, its SOLVED

Not always the case. Only some programs.
Anyways, I think it would be better if you read the contents of the GNU GPLv3. You might be mistaken of some things.

hi i have a similar problem to your:
I'm using visual studio express edition and windows SDK compiler
I'm using an external library with it'own license
I'm using Qt creator as developing environment
'm using Also the Qt libraries 4.8.5 non commercialSo each "tool", i think impose it's own licenses so at the end what i've should do? I want to release my software opensource and free( i think GPLv3 is the right license), i have to include each license in the package?? how i know if some licenses are in contrast. and what about copyright, i have to register the software somewhere to get copyright notice???
Thanks

ceora it's all really rather simple. Visual Studio and Qt Creator are just code editors: they don't impose any licensing on you, ever. I'm not sure about SDK compiler, but it should not cause any problems here, either.
For Qt (since you don't have the commercial license) your options are: LGPL or GPL. If you choose GPL, your code is required to be GPL, too. If you choose LGPL, your code can have any license (including proprietary, commercial EULAs). In all cases, you need to include the license for Qt with your code - so that users can read about their rights.

Everything now relies on that single library. What is it's license?

Looks BSD-ish, and definitely Open. As far as my limited knowledge says, you can use this safely in your app. Happy coding :)
