I have a Kubuntu system where I installed the first GIF library I spotted -- one called giflib3g. This passes the configure tests and installs a /usr/include/gif_lib.h but the library is not compatible with KHTML because it is missing GifFileType member UserData. Switching to libungif4 resolves that. Can a check for that member variable be added to kdelibs' configure checks to ail out before compilation? -- KDE Quality Team GPG: FEA2 A3FE
