Just out of curiosity how do those of you that do Qt based development deal with the likely version mismatch between the Qt system libraries (in /usr/lib and likely other places) and the libraries used for development? For example, I'm using Qt 3.3.5 at work on a SuSE 9.2 system that uses Qt libs at version 3.3.3 (or something like that). We install the latest version of Qt 3 in /usr/local/qt and build. Then we add the appropriate lines to .profile to point the compiler and apps that we build to the right location for the 3.3.5 version. Our apps depend on MySQL so we build the qsqlmysql plugin too. We seem to have intermittent problems with the apps going to the wrong library location for libqsqlmysql.so. Do you overwrite the older delivered libs with the built ones? It seems like that would be a problem with version mismatches. Further, when you deliver an app do you customarily deliver the newer Qt libraries for the app and leave the system libs alone?
