Hi,

I'm trying to emerge systemsettings 4.2.0, but it fails every time:

It seems it can't find "_XiGetDevicePresenceNotifyEvent". This should be exported and found in libXi: nm /usr/lib/libXi.a | grep XiGetDevicePresenceNotifyEvent which I updated to 1.1.3 (latest stable).

Any ideas? I'm just a couple of packages away from 4.2!

I've updated libXext libXft libXau libXdmcp and libXpm, libxkbfile to latest stable, still no go

It seems it's not a kde problem, but a libXi + gcc one.

This test code will not link with gcc 3.x:

Code: Select all

#include <X11/extensions/XInput.h>

extern "C" {
            extern int _XiGetDevicePresenceNotifyEvent(_XDisplay *);
}



int main()
{
        int xitype;
        XEventClass xiclass;
        Display* display;

        DevicePresence(display, xitype, xiclass);


        return 0;
}

(the above is what x11helper.cpp contains)

But, will link with gcc 4.x:

gcc -o test test.c -lXi

So, in a nutshell, gcc 4.x is "required" for KDE 4? Off to start an emerge world...

Compiles fine with gcc 4.x

actually.. 4.1.*
i had an earlier version of gcc 4 with the same compile problem until i updated gcc to 4.1.2 and recompiled libXi.

same problem here; my gcc is already at 4.1.2, recompiled libXi and libXext libXft libXau libXdmcp libXpm libxkbfile. No success...

any hint?
