And it would yield the same bonus point in an application as using LyX would...

I am reasonably sure that the scenario you describe cannot occur with only a single version of Qt on your system. If you only used only packages form your distribution the only explanation I have is that the development package you use (i.e. libqt4-dev) does not match the installed libraries. Either there's a difference in version of both, or you use the development package with a set of defines that's incompatible with the the installed version. The latter seems actually be rather likely as qFlagLocation is only used if QT_NO_DEBUG is _not_ set, i.e. you use the Qt in "debug" mode. The system Qt is most likely not in debug mode. If this is the reason you need to make sure that QT_NO_DEBUG is defined when you compile LyX. I have no idea how Ubuntu packages the Qt development package, but I guess configuring LyX with "CXXFLAGS=-DQT_NO_DEBUG ./configure" or similar might help. Andre' PS: > could you please elaborate on how to use 'setting LD_LIBRARY_PATH'? > i'm not sure that i understand what you mean. That's only relevant for the case where you have multiple versions of Qt on your system, so let's ignore this for now.

Andre' for your information, when i compile lyx (either 1.6.1/2/3), i get this info when finished: Is it possible that you have two versions of Qt installed, accidentally? Is it possible that the Qt libraries and Qt headers are not the same? Are you sure that you managed to completely uninstall the old LyX? You might try compiling LyX and then NOT installing it, but rather running it "in place". So, after compilation finishes, type "src/lyx" to run it. Richard Richard
