I am trying to build kdelibs from your svn tree. I'm building on a system with KDE 3.5.10 installed. The following packages are installed: tqtinterface cups poppler pcre libxml2 libxslt qt-3.3.8b dbus-qt3 qca-1 qca-tls arts I have not rebuilt arts. In the kdelibs build script, I'm using the --disable-dnssd option. As we discussed previously, seems I either need to install an avahi package or use the --disable-dnssd build option. Without that option the build fails quickly. However, your build system is looking specifically for avahi-qt3 and avahi-client. I believe those are Debian-specific package names. Eventually I will test building kdelibs with avahi installed. Right now the kdelibs package fails to build: In file included from /usr/lib/qt/include/qobject.h:48, from /usr/include/tqobject.h:32, from /usr/include/tqiodevice.h:26, from /usr/include/tqdatastream.h:26, from /usr/include/tqvaluelist.h:26, from ./kxerrorhandler.h:28, from kipc.cpp:35: /usr/lib/qt/include/qevent.h:64: error: expected identifier before numeric constant /usr/lib/qt/include/qevent.h:64: error: expected `}' before numeric constant /usr/lib/qt/include/qevent.h:64: error: expected unqualified-id before numeric constant /usr/lib/qt/include/qevent.h:145: error: expected `)' before 'type' /usr/lib/qt/include/qevent.h:146: error: declaration of '~QEvent' as non-member /usr/lib/qt/include/qevent.h:147: error: 'Type' does not name a type /usr/lib/qt/include/qevent.h:148: error: non-member function 'bool spontaneous()' cannot have cv-qualifier /usr/lib/qt/include/qevent.h: In function 'bool spontaneous()': /usr/lib/qt/include/qevent.h:148: error: 'spont' was not declared in this scope /usr/lib/qt/include/qevent.h: At global scope: /usr/lib/qt/include/qevent.h:149: error: expected unqualified-id before 'protected' /usr/lib/qt/include/qevent.h:151: error: expected unqualified-id before 'private' /usr/lib/qt/include/qevent.h:153: error: function definition does not declare parameters /usr/lib/qt/include/qevent.h:156: error: 'friend' used outside of class /usr/lib/qt/include/qevent.h:157: error: 'friend' used outside of class /usr/lib/qt/include/qevent.h:158: error: 'friend' used outside of class /usr/lib/qt/include/qevent.h:159: error: 'friend' used outside of class /usr/lib/qt/include/qevent.h:160: error: expected declaration before '}' token make: *** [kipc.lo] Error 1 make: Leaving directory `/dev/shm/kdelibs/kdecore' make: *** [all-recursive] Error 1 make: Leaving directory `/dev/shm/kdelibs/kdecore' make: *** [all] Error 2 make: Leaving directory `/dev/shm/kdelibs/kdecore' make: *** [all-recursive] Error 1 make: Leaving directory `/dev/shm/kdelibs' make: *** [all] Error 2 I hope that information helps.
