It's not just launchpad and building but also no proper C++11 support so now we have to keep old stuff around just for those not willing to upgrade. So in the end it's also the main developers who will say enough is enough.

And again,no one is forcing you to update. Just stick to whatever Kodi version you have and use it.

to be fair this is also a question of backporting more recent gcc.
And help with packaging would be welcome. If anyone wants to step up: Please provide a _tested_ gcc >= 6 for ubuntu 14.04 on launchpad, so I can copy it to our PPA.
I'm aware there are builds out there, but I cannot find a reputable "stable" PPA.

Is this really enough? Without replacing all of libc and things?

I don't think this is enough. The libstdc++ ABI changed with gcc 5. C++ code built with gcc 4 won't work with libstdc++ from gcc 5. You'd have to rebuild all dependencies with gcc 5 that link against libstdc++. They didn't bump the so version when they made this change either, so you can't ship both libstdc++. This is quite a risky change.

Yeah - will open pandora's box ... as 17.2 is redone now and still working for 4.8 we can now calmly decide what we will do with Leia v18.

yeah, agreed. Thats what I was getting at with "tested" gcc 5 and "deps of dependencies" earlier.

Something different happened after the kodi upgrade. Now the system write .kodi in my home/lino.
For some seconds I see a black windows and then nothing.
Following the error:
lino@lino ~ $ kodi
libEGL warning: DRI2: failed to authenticate

libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so

I think I told it now twice: your system is completely broken. Your issues have nothing to do with kodi, but with a totally broken userspace - starting with a VAAPI wrapper driver and missing user permissions.
