Need a hint: Why can't I copy collectord to another machine from same OS on same arch and execute?

[bgewehr]

When I copy collectord to a new debian 9 container (it was compiled in another one of the same image on the same machine), it does not execute, saying file not found:

root@collectord1:/usr/local/sbin# ls -l

No idea OTOH, but running strace -f /usr/local/sbin/collectord may give a hint?

[bgewehr]

Does this explain to you what happens?

I tried to execute /mnt/ems/collectord on both containers. Only the one where it was built runs the file correctly:

root@i386-debian1:/# /mnt/ems/collectord

Possible values for target:

  tcp:<host>:<port>   Connect to TCP address <host> at <port> (e.g. NetIO)

The pid /var/run/ems-collector.pid file exists on both, so does the /etc/default/ems-collector conf file.

OK. All my fault. Wrong image source refered to, wrong arch was taken. now, i386 arc, all good.

BUT: What is the smallest way of providing all necessary so libraries from boost?

root@collectord2:/# collectord

rectory 

[bgewehr]

Found that it is enough to install

apt-get install libboost-system1.62.0
apt-get install libboost-program-options1.62.0

Now it's working as expected. Sorry for being dumb.
