libmmal_core.so missing

Question

I'm sorry to say that I'm a complete newbie to linux and Raspberry Pi. I installed Raspbian on my pi years ago and just started working with it again.

I'm trying to install kodi on my system but after the regular install via apt-get and trying to start I get "error while loading shared libraries: libmmal_core.so: cannot open shared objekt file: No such file or directory".

I've tried about everything I could find online; can't seem to find anything though. Here https://www.raspberrypi.org/forums/viewtopic.php?t=51925&p=415168 was an idea I wasn't able to try out simply because I had no idea what the guy in the last post was talking about.

Any help? The file cannot only not be found but doesn't exist at all.

You need to determine:

1. If the library is present (it should be).

   The path is /opt/vc/lib. If that's not there or doesn't contain that library, run sudo rpi-update and make sure it at some point says "Updating VideoCore libraries".

2. If the library is in the linker path (it should be).

   For this:

   ldconfig -p | grep libmmal
   

   You should see it listed. If not

   echo /opt/vc/lib > pi_vc_core.conf
   sudo chown root.root pi_vc_core.conf
   sudo mv pi_vc_core.conf /etc/ld.so.conf
   sudo ldconfig
   ldconfig -p | grep libmmal
   

   It should be there now.

3. What kodi actually links to.

   I believe the binary is in a weird spot because it's started via a script. Try:

   ldd /usr/lib/kodi/kodi.bin
   

   What you don't want to see there is ????? after libmmal_core.so. =>

For me the solution was simply installing libraspberrypi0:

sudo apt-get install libraspberrypi0

Note that rpi-update shouldn't be necessary nowadays, as updates are included in raspberrypi-kernel and raspberrypi-bootloader.
