            No support? ;)

            Have you RTFM or looked in the forum? It's a known compile error with a known workaround.

            Bye.

            Poor Support
            I can not get hydrogen to compile. I emailed the author weeks ago with no response:

            if g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../lib -I/usr/lib/qt/include -I/usr/X11R6/include -DQT_THREAD_SUPPORT -D_REENTRANT -O3 -MT PreferencesDialog.o -MD -MP -MF ".deps/PreferencesDialog.Tpo" -c -o PreferencesDialog.o PreferencesDialog.cpp; \

            then mv -f ".deps/PreferencesDialog.Tpo" ".deps/PreferencesDialog.Po"; else rm -f ".deps/PreferencesDialog.Tpo"; exit 1; fi

            PreferencesDialog.cpp: In constructor `

            PreferencesDialog::PreferencesDialog(QWidget*)':

            I also get errors when trying to compile the latest CVS build.
