Re: [Yade-dev] doc warning on Qt4->Qt5

[Anton Gladky]

Hi Bruno,

the idea is to drop deprecated (and duplicated) Qt4-code,
when it will be reasonable. If you think there are 14.04
users, then you are right, it is better to wait till 14.04 gets
EOL and then drop Qt4 from the code and declare Yade
as Qt5-only.

Regards

Anton

Hi Anton,
I'm not sure I get all aspects of your question but I would tend to 
choose the energy-minimizing solution.
For binary packages (I guess it is your main question) I don't think it 
is worth it to support 14.04 if it needs more efforts. Backporting 
libqglviewer, typically, is a waste of time since we are in the tail of 
14.04. For the moment the 14.04 binary builds without problems, so let 
it be.
If in the futur some changes become painful because of Qt4 we can just 
drop 14.04 support at that point.

Would it be reasonable?

In my mind, this is not really related to the resurected comment. I 
found the comment more useful for people _compiling_ on 14.04 (and 
possibly on other exotic distros, clusters, etc.) as a pointer to a 
potential source of trouble.


Cheers

Bruno
