Hi I was trying to build the Qt 4.5 RPM from Koji on RHEL 5.3, and half way through, the compilation failed. From the error messages, I guessed it had something to do with SQLite. I then built (again from Koji) SQLite 3.6.12 and updated the RHEL machine. Now Qt compilation worked fine. When I installed Qt (& the devel package) on another machine, Qt Assistant failed to start. Updating SQLite on that machine fixed that too. So I guess we need a sufficiently new version of SQLite as a dependency (& BuildRequires) for Qt 4.5. regards, Syam
