Why not recommended ???
I hear first time about it.
Yes, there are some differences in static linking, for example with
plugins.
You have to static link Qt plugins too (add plugins += to .pro file
and init plugins in code).
Other "bad thing" is that you'll be unable to reuse Qt libs: for
example you have two Qt based applications, In case with shared
linking you'll got that Qt libs will be loaded in memory only once.
It's nevermind how much applications use shared library (Qt libs in
our case), this lib will load only once. But with static linking
you'll got another appearance. Every Application will load it's own Qt
libs. This case got overhead. But If in linux there exists software
repositories , and system can guaranty to you that there are exists Qt
libs. In windows and windows mobile there no such way. In any case you
have to provide Qt libs with your application during deploy.
That's why static linking is better chois for deploying on Windows
Mobile, I think.
In other cases there are no differences.
As for qconfig and "-config" flag to use custom configuration is other
way, but using this way you need to clear understand what to leave and
what to exclude from Qt. During Static linking all this things made
for you by compiler (excluded all unused code during final linking ).
Yes I made this before, and didn't find any problems. Also you'll got
faster loading speed, using static linking.
Hi Rudenko Eugene,
I heared of creating static link is not recommended.
Do you have done it before?

You can link with Qt libraries using static linking, As I now MS
compiler have better optimization for static linking then gcc.
I think you'll got result size under 10Mb at all, with static linking.
You can try.
Also you can find Arora browser as example for building browser using
Qt.
