Thanks Ivan, for your explanation. So I removed libqt2-dev and then re-installed libqt2-dev. Now That the error in the previous mail is gone. libqt2.2-dev files are (partly) overwritten by libqt2-dev files and these are the files kpgpcrypt expects I suppose.
apt-get gives a lot of messages like this: dpkg - warning, overriding problem because --force enabled: trying to overwrite `/usr/lib/qt2/include/qiodevice.h', which is also in package libqt2.2-dev I wonder what will happen when the I try to link or run the application (kpgpcrypt): I need to overwrite libqt2.2 with libqt2 everytime I want to start this application? And when some kde2.1 application really needs libqt2.2 I need to do the opposite? libqt2.2-dev and libqt2-dev have also importent files in common (according to 'apt-get install libqt2' output when libqt2.2-gl is installed) dpkg - warning, overriding problem because --force enabled: trying to overwrite `/usr/lib/qt2/lib/libqt.so.2', which is also in package libqt2.2-gl dpkg - warning, overriding problem because --force enabled: trying to overwrite `/usr/lib/libqt.so.2', which is also in package libqt2.2-gl Now I get a error on kde includes when continuing to compile kpgpcrypt. So I guess that kpgpcrypt is not ready for kde2.1 as it was not ready for qt2.2... I am running kde2.1, there is no way of compiling/running kde2.0 applications on a kde2.1 system I guess? Gerralt
