No. firstrunUI.h is a temp source file generated by Qt moc pre-compiler. On 
any linux box (like Mandriva for example !!!), i have the same error.

I have tried to solve this problem accordinly with Mandriva team... but 
without success. This problem is very wierd...

To solve it, just going into digikam/digikam folder, i start "make 
firstrunUI.moc". all temp source code generated by moc program will be done. 
You can compile all digikam after that. Later, nothing will be done on 
firstrunUI...

moc compiler is used to build GUI from xml file genrated by QtDesigner 
program. I hate it. I prefert build GUI from scratch because it's very easy 
to make gui/layout/widget using Qt API.

When i will more free time, i will rewrite this firstrunUI part from scratch 
(:=)))...

yes, it's enough. I'm working like this everytime.

Don't forget that to debug a source code, gdb is not enough. You need to use 
valgrind program to check memory allocation/using/leak. default settings is 
available in HACKING file from svn. Read the valgrind doc before. This tool 
is really incredible (:=))).
