[Interest] Interest Digest, Vol 114, Issue 39

[Roland Hughes]

So,

Just to be clear.

You are saying QtC has the latest version of Qt 5.x compiling and 
running on Scott's RHEL version though Qt-project does not?

That somewhere inside QtC all the compiler and OS versions abandoned by 
Qt-project mid Qt 5 have shiny happy versions of the latest 5.x?

If one defines "platform" as compiler version + OS version (to make 
wording simple) it would seem to me that one Qt-project abandoned it and 
started writing to newer compiler and platform version it would become 
impossible to make a working fork.

We had this problem with compiler standards quite a few years ago. C++11 
was supposed to be the minimum supported but the CI was (and probably 
still is) compiling with only the latest standard. I ran headlong into 
this when people were using stuff from from a much later C++ standard in 
the examples and I think a few other places.

Once they start using things that don't exist, or worse, exist 
differently, getting there from here is a very difficult journey.

There are some who every now and then still need something related to Qt 3. Somewhere Qt 2 is still in use. Perhaps Qt 1 even, but personally not certain about that. Qt 4 based systems of course and majority of customers are with Qt 5 currently.
