DVBSky S960 (v2) installation issues

Sooooo…
I reinstalled, only thing I did after freshly installing was apt-get gcc and make.

I then downloaded the (supposedly) correct driver for kernel 3.14.x - 3.17.0.

It’s manual said

—Compile and install driver
1)Enter the source code directory

2)Check and choose one of the target systems, run ‘uname -a’ to get os informaton.
./v4l/build_x86.sh if build for 32 bit system os to support multi-standard, include DVB-T,DVB-T2 and DVB-C.
./v4l/build_dvbc_x86.sh if build for 32 bit system os to support DVB-C.
./v4l/build_x64.sh if build for 64 bit system os to support multi-standard, include DVB-T,DVB-T2 and DVB-C.
./v4l/build_dvbc_x64.sh if build for 64 bit system os to support DVB-C.

3)Compile the source code:
make

I used the x64 for the Vero4k version of osmc.
The .sh-File contains

#!/bin/bash

cp ./v4l/sit2_op.o.x64 ./v4l/sit2_op.o
cp ./v4l/sit2_mod.dvb ./linux/drivers/media/dvb-frontends/sit2_mod.c

and “make” results in

osmc@vero:~/media_build-bst-14$ make
make -C /home/osmc/media_build-bst-14/v4l 
make[1]: Verzeichnis „/home/osmc/media_build-bst-14/v4l“ wird betreten

sorry for it being German…
So you mentioned earlier I might be using the wrong toolchain… How would I use the correct one in this?

Edit:
From the other mentioned HowTo ([HowTo] Compile DVB Media Build drivers on RPi 3) I tried to copy the /boot/config-3.14.29-55-osmc to /lib/modules/3.14.29-55-osmc/.config to avoid the make-process not finding any .config… But that resulted in the error mentioned in my first post.

Need help turning OSMC into the proper build environment for compiling a wireless adapter driver - #2 by fzinken here you said

You just run make under kernel-osmc after a clone.

maybe that’s it? How would I do that?
