Install CASES 4.3.1 on (K)Ubuntu 18.04 - solution that worked for me

Recommended Posts

UPDATE:

 

CAESES 4.4.1 comes with the lastest libpng12.so.0.59.0 and all the symbolic links set correctly (so forget about steps 1. - 4- below).

 

However, removing libz (step 5) is still required under (K)Ubuntu 18.04.

 

 

ORIGINAL POST:

 

CASES 4.3.1 doesn't run on (K)Ubuntu 18.04 out of the box because it requires libpng12 that isn't readily available for 18.04.

 

Here my work around:

 

  1. Get libpng12 (64-Bit) from https://packages.ubuntu.com/xenial/amd64/libpng12-0/download
    (This is the latest version for (K)Ubuntu 16(!).04)
     
  2. Extract libpng12.so.0.54.0 from the downloaded .deb package (I used ark and just looked through the file until I found it in /lib/x86_64-linux-gnu)
     
  3. Copy libpng12.so.0.54.0 to the lib-directory of your CAESES-Installation (usually something like ~/CAESES_4.3.1_Linux.x86_64/lib/Linux.x86_64)
     
  4. Set the symbolic link ln -s libpng12.so.0.54.0 libpng12.so.0 (in the lib directory)
     
  5. REMOVE libz.so  libz.so.1  libz.so.1.2.5 from yor CAESES-lib-directory
    (They are too old and apparently the newer version comes with 18.04)
     
  6. Make sure your proprietary graphics driver is installed.
     

Worked like a charm for me. Hope it helps.

Regards,

Bodo

Hi Bodo

 

Thanks, your solution did help me the libpng12-error

I also needed to install the canberra-gtk-module, by simply doing sudo apt install canberra-gtk-module

 

Afterwards I had a problem with the licensing:  it returned the error:

The license file contains hardware keys not corresponding to this workstation.
Please send us an email with the failed identifiers!

So i tried to start caeses by "./CAESES -resetauth"
But it didn't work out. So Joerg, here comes my e-mail :).

 

Regards

Bram
