Ok, I found the solution myslef. More here: https://bugs.launchpad.net/ubuntu/+source/kdbus/+bug/73780

First of all, thanks to the developers, great work! But: I got the same problem during compilation... Here is the workaround: According to http://dbus.freedesktop.org/doc/dbus-specification.html DBUS_NAME_FLAG_ALLOW_REPLACEMENT has a value 0x1, and DBUS_NAME_FLAG_REPLACE_EXISTING (also used in qdbusconnection.cpp) 0x2. So, add the following lines to kdbus-0.8.5/src/dbus-qt3-backport/dbus/qdbusconnection.h: #ifndef DBUS_NAME_FLAG_ALLOW_REPLACEMENT #define DBUS_NAME_FLAG_ALLOW_REPLACEMENT 0x1 #endif #ifndef DBUS_NAME_FLAG_REPLACE_EXISTING #define DBUS_NAME_FLAG_REPLACE_EXISTING 0x2 #endif I know, this is, to say the least, a real dirty solution, but it works fine :)

and my patch: //if (modeFlags & AllowReplace) if (modeFlags & !AllowReplace) //dbusFlags |= DBUS_NAME_FLAG_ALLOW_REPLACEMENT; dbusFlags |= DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT; it's kinda confusing me since the change is not only a name change but also a logical change. I'm not sure it will work as intended. As you've said, the spec says DBUS_NAME_FLAG_ALLOW_REPLACEMENT uquals 0x1 but the implementation says it's DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT; that equals 0x1

This is the patch I ended up making. Note that this probably makes no difference to anything, because this part of the code deals with whether or not another process can 'steal' kdbus's connection name, but kdbus doesn't use a named connection to dbus anyway. --- src/dbus-qt3-backport/qdbusconnection.cpp (revision 510765) +++ src/dbus-qt3-backport/qdbusconnection.cpp (working copy) @@ -373,8 +373,15 @@ return false; int dbusFlags = 0; +#ifdef DBUS_NAME_FLAG_ALLOW_REPLACEMENT if (modeFlags & AllowReplace) dbusFlags |= DBUS_NAME_FLAG_ALLOW_REPLACEMENT; +#elif defined DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT + if (!(modeFlags & AllowReplace)) + dbusFlags |= DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT; +#else +#error Neither DBUS_NAME_FLAG_ALLOW_REPLACEMENT nor DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT are defined. +#endif if (modeFlags & ReplaceExisting) dbusFlags |= DBUS_NAME_FLAG_REPLACE_EXISTING;

after a quick check (only God knows why hadn't I do this before), I found the answer: [geek@toni kdbus-0.8.5]$ grep -R DBUS_NAME_FLAG /usr/include/dbus-1.0/dbus/ /usr/include/dbus-1.0/dbus/dbus-shared.h:#define DBUS_NAME_FLAG_PROHIBIT_REPLACEMENT 0x1 /usr/include/dbus-1.0/dbus/dbus-shared.h:#define DBUS_NAME_FLAG_REPLACE_EXISTING 0x2 instead of ALLOW, it should be "not PROHIBIT" :)

Thanks for the investigation. It turns out that particular macro changed name between dbus-0.50 and dbus-0.60. So, I take it you guys are trying to compile kdbus with dbus 0.50 or earlier :-) In kdbus 0.8.6 I fixed it to compile with either dbus 0.50 or 0.60. dbus earlier than 0.50 is not supported.
