where are original packages on my system?
 

Hey what if you ran pkgtool on Slackware 12.2 and removed qt because it seemed like a good idea at the time. Where is the package if you want to bring it back? Isn't it on my system somewhere?

Once you remove a package, it is gone. Check your Slackware12.2 disc, and go to the /l directory, and issue the comand: installpkg qt-3.3.8b-i486-2.tgz

What happens if you install a slackbuild for qt4 instead? Can the KDE 3.5 even use it? Or what if you install qt4 and qt3.8? Can programs then pick whichever one they want to use or do all kinds of conflicts and problems arise?

How did that work so fast? It says it's 16 megabytes. I guess it's not the entire SDK but just the framework or something? I don't know. I mean I just typed your command and instantly konsole and konqueror and all my qt based stuff worked again. But I just compiled qt4 recently and it took all day. The source download was like 150 megs I think.

What you installed was a package containing QT3 already compiled, not the source code. For the source to QT and any other packages found on your disc look in the /source folder (that is if you downloaded the DVD iso which contains packages and sources for all packages).

Yeah but the source code for the qt4 SDK was like 150MB and this qt3 binary on the slack disc was 16MB. 150 megs of source doesn't compile into 16megs of binaries and libraries, does it? (Maybe it does, I don't know.) I figure either it's just a small part of qt3 or qt4 is massive compared to qt3. I guess it doesn't really matter. Nvm.
