Yes. The GuiImplementation files are missing from Makefile.dialogs. Sorry Bo, that is no scons advantage, you have to add them to scons.manifest as well (which is already done).
The 'scons advantage' in another email means there is always one command to run. No autogen.sh, no configure. scons runs (cached) configure every time and ensure a correct build. In this moc case, I have to ask again: ****is it time to rename .C to .cpp now? ****** We are at the end of *big* changes and all big branches have been merged. I would propose that we do this now, before we all turn to the bug fixing mode. (This is relevant to the moc problem because scons can not automatically moc the files because of the .C extension.) Cheers, Bo
