If you want qt3support put it in /etc/make.conf. Despite the fact that portage will tell you to enable qt3support for package XYZ, doing just that won't work. The qt3support USE flag only applies to the Qt packages, not to those packages that might require Qt 3.x support. I know. Specifically, it applies to: x11-libs/qt-core x11-libs/qt-gui x11-libs/qt-opengl x11-libs/qt-sql Enable it for all 4 and you will have Qt 3.x support for all Qt app's that are satisfied by the backwards compatibility support in Qt 4.x. The problem is that if you don't have qt3 support, Portage tells you to enable qt3support for _one_ of those packages. If you do exactly what portage tells you (enable it for that one package), then portage will complain and tell you to disable it for that package. At least that's what always seemed to happen for me. -- Grant Edwards grant.b.edwardsYow! I'm in direct contact at with many advanced fun gmail.comCONCEPTS.

I think you need to install the euses command, if you have not already done so; its package name is the same as its command name. If you then run: euses qt3support it will tell you exactly which packages are candidates for the USE flag. It sorts out lots of Portage's vagaries in this area. -- Regards, Dave [RLU #314465] == dwn...@ntlworld.com (David W Noon) == signature.asc Description: PGP signature

I tend to -- probably misleading myself that I'm saving on something (disk space, update time, who knows). Usually, if I need support for something, it is more than one package or that one package will want the support enabled for other packages it builds on as well. I'll have to remember that -- it will probably avoid similar problems with other subsystems. Glad you got it figured out tho. At least by learning it the hard way, you won't forget it. ;-) Sad to say, but I probably will. Hopefully google will find my post. Honestly, that's happend to me a couple times: I trip over a problem, and when looking for the solution Google finds a 6 year old thread (I started) from the first time I ran into the problem. It's really embarassing when your working with somebody else on the problem and _they_ stumble across that old thread containing the solution. -- Grant
