Re: [Interest] Qt 5.15 pull out of open source?!

[Yuvraaj Kelkar]

I hope what Robert meant was that if you want someone to fix bugs for you on an 
old LTS, then you have to pay for the support.
Because that would make a LOT of sense.

Thanks,

Re: [Interest] Qt 5.5 DEB (or other install package) for Ubuntu 14.04 out there?

[Yuvraaj Kelkar]

Qt5 libraries do exist on Ubuntu 14.04.
If you have built your deb on 14.04, then the debhelper should have
put in the correct dependency information.
If you build on a version > 14.04 and try to run on 14.04 then your
debianization scripts need to be explicit about versions.

I used to do this by using a 14.04 VM. Now I use a 14.04 Docker image.

  I am just trying out the nano browser in Qt 5.5 on Windows 7 64-bit
  and find it almost unusable.
 
  Loading **any** website is slow but it is particularly noticeable with
  Google Maps.  It can take more than a minute to render the initial map
  and then zooming in first shows just a scaled and pixelated version of
  the map and then it can several minutes for the details to be rendered
  properly.  Also, switching from map to Earth/Satellite view seems to
  take forever too.
 
  What could be causing this incredible slowness?  It's not the network
  itself as the same sites load instantaneously in other browsers like
  Chrome and Firefox on the same machine and there is no proxy involved.
 
  Given that the primary use case I had intended for the Qt browser
  implementation is Google Maps, this is all very worrying!

Re: [Interest] memory fragmentation?

[Yuvraaj Kelkar]

Can you post the error you hit?
I've been compiling Qt on x86 and x86_64 for Windows and Ubuntu,
static and dynamic since 4.6.x, through to 4.8.1

My steps:
1. Get the latest Qt tarball/zip from the ftp site. Get the latest
openssl tarball. Extract both.
2. Compile openssl with nasm, point its output dirs to $QTDIR/lib
3. For static compile only: Update the windows mkspecs with -MTd
instead of -MDd.
4. For Windows, configure Qt with configure.exe -opensource -openssl
and build.

It has worked pretty consistently for me.

 It's called win32-msvc2008.

 win32 doesn't stand for the number of bits, it stands for the Win32 API.
 That is not changed in 64-bit mode.

 Simply select your MSVC 2008's 64-bit mode and Qt will compile in 64-bit.
 That's how it has been for... oh, 7 years?

Re: [Interest] Speaking about Qt

If your audience is app developers:

and the IOS people to the twitter feed of Qt4IOS:
http://twitter.com/Qt4iOS
and the website (still under construction):
http://mediator-software.com/

and tell them about RIM's BB10 - that supports Qt.
http://crackberry.com/press-release-rim-launches-blackberry-10-platform

Then casually mention that Qt (and QML) also works on all primary
desktop platforms, and then say something about native apps and write
once run everywhere.
