Ubuntu – How to install the Perforce client

As seen in the comments your Library is located at /usr/lib/oracle/12.1/client/lib/, but your path just includes /usr/lib/oracle/12.1/client/bin... you see why it can't find the library?

You can expand your LD_LIBRARY_PATH with the /usr/lib/oracle/12.1/client/lib/ directory (in your .profile or .environment or .bash_profile or (if you want it for all users) in the /etc/bash.bashrc file) - i don't know if sqlplus takes care of the LD_LIBRARY_PATH - just have a try.

To see to what LD_LIBRARY_PATH is set you have to type:

echo $LD_LIBRARY_PATH

(note the $ if you want to read the value!)

Hope this helps!

.txz is short for .tar.xz, just as .tgz is short for .tar.gz. You can unpack it like a .tar.xz archive:

Run tar xf *archive*.txz, since tar will automatically figure out how an archive is compressed and decompress accordingly.

Assuming you downloaded this file (or that one), linked to from here and listed under "Ubuntu 14," there are a few points to keep in mind:

1. Most archives for software kindly keep everything in a top-level folder, but this one doesn't! Therefore, I suggest creating a cinelerra folder, putting the archive in the folder (or downloading it to there in the first place, if you haven't already), and unpacking it there:

   mkdir cinelerra
   cd cinelerra
   wget http://cinelerra.org/2015/downloads/cinelerra-4.6.mod-ubuntu-14.04.1-x86_64.txz
   tar xf cinelerra-4.6.mod-ubuntu-14.04.1-x86_64.txz
   

2. Generic instructions for installing software from compressed tar archives are often instructions for installing from source, as source code is commonly packaged this way. However, Cinelerra is distributed for Ubuntu as a precompiled binary in a compressed tar archive. Thus, as the README file says:

   Run `./cinelerra` from this directory.  That's it.
