Version: 2.0.0 (using Devel)
I have got a problem with jpeg autorotation at import from a camera sd card. See bug #274947. Autorotate seems to fail, but there is no error message at STDOUT/STDERR.
Debugging the process lead me to

static void jpegutils_jpeg_error_exit(j_common_ptr cinfo)
jpegutils_jpeg_error_mgr* myerr = (jpegutils_jpeg_error_mgr*) cinfo->err;
kDebug() << buffer;

There I can see "kDebug() << buffer;", which would write the desired error output. But ENABLE_DEBUG_MESSAGES is not defined. It's commented out in line 83:
> //#define ENABLE_DEBUG_MESSAGES
Why should one not want to see an error message, if an error occured? Seeing an error message might have helped debugging the problem.
I enabled the gentoo "debug" USE-flag for digikam, hoping that this would magically define ENABLE_DEBUG_MESSAGES. But that did not happen.
Maybe I just don't understand all KDE-debugging guidelines.
I'm aware of kdebugdialog and I like the concept very much! :)
But I don't understand the above issue.
Can you bring light to this issue, please? Thx!
No error message, although error happened and is detected by the programm.
Error message is printed out to STDOUT or STDERR.
I forgot to mention Bug #139197, where you can find related info in comments 7 and 10.
Please don't misunderstand me. I don't want to be a smart ass. I admire you guys, putting all this stuff together, creating almost wonders!
I just want to understand how things work.
It's simple. Just use this option to pass on cmake script when you configure : "-DENABLE_DEBUG_MESSAGES"

Thanks for the info.
So I would say, this flag should be enabled, if the gentoo USE flag "debug" is enabled. Which is not the case for media-gfx/digikam-2.0.0_beta6.
Any gentoo maintainer for media-gfx/digikam-2.0.0_beta6 ebuild listening? Or do I have to file a separate gentoo bug?

That was a one-liner. Re-sync your overlay and it should work (with USE=debug).
Synchronized overlay and rebuild digikam with USE=debug.
build.log says "-DENABLE_DEBUG_MESSAGES=ON":

But error message is still not printed. :(
Using gdb to step through execution does not reach line
> kDebug() << buffer;
So I guess ENABLE_DEBUG_MESSAGES is not defined, when compiling

It makes sense to display the message on the console when an error occurs
and the operation is aborted by longjmp.
