Rudder

We use script /opt/rudder/bin/run-inventory to run FusionInventory. However, it works either by calling the perl shipped with Rudder (pre-4.3), or calling fusioninventory-agent from the path (for agent-thin)

It does not contain the logic to call FusionInventory from system perl

calling

perl  /opt/rudder/bin/fusioninventory-agent --config=none --no-task=Deploy "$@" 

is not sufficient, as it missed dependencies

Can't locate UNIVERSAL/require.pm in @INC (@INC contains: /opt/rudder/share/fusioninventory/lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /opt/rudder/share/fusioninventory/lib/FusionInventory/Agent.pm line 8.

I had to install:
perl-UNIVERSAL-require
perl-File-Which
perl-libwww-perl
perl-XML-TreePP

and only then I could run inventory, with following output

[error] Can't locate object method "isEnabled" via package "FusionInventory::Agent::Task::Collect" at /opt/rudder/share/fusioninventory/lib/FusionInventory/Agent.pm line 473.

As a side note, there still are libs in - is it expected ?
running

perl -I /opt/rudder/lib/perl5 /opt/rudder/bin/fusioninventory-agent --config=none --no-task=Deploy "$@"
