Static compile with jpg support

[ksqt]

Can I do a static compile with open source version and still get jpg support for the app?

[wysota]

Yes. You have to compile jpg support into the library itself (not as a plugin).

Sorry for the newbie questions, but, how do i go about doing this?

Depends on which Qt version you use. For Qt4 it should be enough to compile Qt in static mode (check FAQ for details) and to use libjpeg which comes with Qt (or to have a static libjpeg installed in the system). For Qt3 (AFAIR) there was some switch to compile jpeg support directly into Qt. Run configure with "-help" parameter and look for it.

I'm using Qt 4.1.1. With the open source version for windows(installed with the .exe) my program works fine. I can manipulate, etc. jpeg images. But if I try the open source "source" and build it, I cannot work with jpeg images. (configure -static)
Perhaps I am missing a switch during "configure"...

Also, how do I use "libjpeg"?

[wysota]

-no-libjpeg ........ Do not compile the plugin for JPEG support.
-qt-libjpeg ........ Use the libjpeg bundled with Qt.
-system-libjpeg .... Use libjpeg from the operating system. See http://www.ijg.org

ah...that is "libjpeg"...
I have already tried that "configure -static -release -qt-libjpeg" and built, but the program will not work. (identical program with shared works )

Check if Qt builds a static libjpeg library. If not, this could be a bug and should be reported to TT.

Where would I check to see if it did build a "libjpeg" library?
Sorry for such newbee-ish questions....

[wysota]

Probably somewhere around src/3rdparty/libjpeg directory relative to unpacked Qt source

[ksqt]

src\3rdparty\libjpeg exists.......so.......?

Are you can use jpg in dynamic compile with open source version ? If yes so i think you can do it with static compile
