[Digikam-users] building it for Mac OS / Windows

Hi there,

I've also managed to build on OS X.

I had to jump just some more hoops to get it going. Some dependencies  
of kde need a ggc 4.2 to compile,
while on Mac OS 10.4 (Tiger) the newest one to be delivered with  
xcode is 4.0.

So you have to get the apple-gcc42 package of macports and then start  
the compilation by typing

sudo port install digikam configure.compiler = apple-gcc-4.2

After that (and of course patching lqr as mentioned) digikam builds.
Before starting it you have to register some processes and start some  
daemons as told
be the notes to all the kde packages you installed with macports.

One file to load was a .plist which actually won't load right away.  
There was a active=no line in it which I had to change to make it work.

Digikam starts then if you manage to locate the executable in

But it's unstable as hell. I usually get about 5 clicks until  
something makes it go down. Last time it took quite an amount of OS X  
with it, leaving me at a new login window.
Therefor my unsaved notes in a text editor were lost and the command  
line given above is made up from memory.
If I just be very carefully with my clicks it just stops loading  
preview thumbnails after about 5 pictures.

As the whole build with all the dependencies took about two days, I  
gave it a try on a windows machine while waiting.
Of course there is no prebuild binary either. The website says so,  
but just redirects to the kde-on-windows site offering in 'kde  
installer', which just as macports compiles things from source.
Albeit said on the website, there is no beta3 package availiable  
within the 'kde installer', so I took the beta1.

It actually builds and starts! But it kept spitting error messages  
about not being able to connect to the dbus server with every other  
dialog box. That's probably the kde installers fault, which just  
didn't succeeded in preparing the whole kde environment.

If this is the state of being for the final release of digikam 1.0.0,  
you better scratch that 'multi platform' off the website. Digikam is  
strictly mono-platform, and this platform is KDE.
Whatever the KDE guys are saying, just because QT4 would enable it to  
run on other platforms than a KDE-based linux desktop theoretically,  
it is just not true at the moment.

So, while giving the older, non-beta releases another try, I have two  

Is anybody testing and developing on Mac OS X or even windows  
machines and therefor interested in bug reports?
Will the whole multi platform thing in general be actively supported  
by digikam, or just used as a sort of marketing buzzword and then  
rolled off to the KDE guys?

Thanks for the work done anyway, and willing to deliver those bug  
reports if wanted,
