Can't load lib on Ubuntu 16.04

When I try to add the module to mesos it fails to start and spits out:

Hi @andrew-t-l

Can you do an ldd on libmesos_dvdi_isolator-1.1.0.so just to verify first?

When you installed mesos, apt-get should have installed all the prerequisite libraries including libprotobuf. Give this a try:

sudo apt-get install libprotobuf-dev

[andrewl3wis]

Hey thanks for getting back to me, libprotobuf-dev is/was already installed and here is the output of ldd:

ldd /usr/lib/libmesos_dvdi_isolator-1.1.0.so

linux-vdso.so.1 =>  (0x00007ffdbad1d000)
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f6ded454000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f6ded08b000)

/lib64/ld-linux-x86-64.so.2 (0x0000558591d53000)

Also for what it's worth, everything seems to run fine on Centos 7.

Thanks for the feedback. Will need to stand up an environment for me to debug. We build the binary on Ubuntu 14.04 and it should be compatible with 16.04, but we don't test or verify on that platform at all.

[dvonthenen]

@andrew-t-l here is one last effort before I stand up an environment. Please give this a try. I number of people on 16.04 have reported these libs dont get installed by default and are the correct ones.

sudo apt-get purge libprotobuf-lite9v5 sudo apt-get install libprotobuf-lite9v5

You may need a reboot after installing the libs.

[andrewl3wis]

No dice, same error. Worked fine with CentOS 7, so might be able to use that for now.

[dvonthenen]

@andrew-t-l: Thanks for the info. I will stand up a 16.04 environment and let you know what I find.

Will reopen if still have issues.
