Sorry for my late answer.
As I stated in my original post, I tried to compile the all Kobo_reader package from github.
I tried to follow the wiki and got stuck with qt compile. The script try to compile qt 4.6.2. The problem
QT 4.8 is also on the repository, I can try to compile it with same parameters. Do I need to apply the patch in Kobo-Reader / patches / qt-everywhere-opensource-src-4.8.0_kobo.patch ?
Thanks in advance.
