DBD::Sybase error - perl

Question

First of all, let me thank you for your time and knowledge sharing, I'm kind of an ignorant in trems of perl modules
I have a 64bit ubuntu Server 12.04, with Perl version 14, subversion 2 (v5.14.2) built for x86_64-linux-gnu-thread-multi and CPAN exploration and modules installation (v2.10).
I'm trying to use a perl script accessing a Microsoft SQL Server and I'm having a really hard time upon the DBD::Sybase module
When I try to install DBD::Sybase CPAN tells me it's already installed:
cpan[1]> install DBD::Sybase
Reading '/root/.cpan/Metadata'
Database was generated on Wed, 29 Apr 2015 14:53:21 GMT
DBD::Sybase is up to date (1.15).
I also find multiple Sybase.pm files on my filesystem, some of them are under Perl path
root#server:# find /* -name Sybase.pm
/home/usriten/download/DBD-Sybase-1.15/Sybase.pm
/root/.cpan/build/DBD-Sybase-1.15-TtUI0T/Sybase.pm
/root/.cpan/build/DBD-Sybase-1.15-kNqdf7/Sybase.pm
/root/.cpan/build/DBD-Sybase-1.15-rZgcTa/Sybase.pm
/usr/local/lib/perl/5.14.2/Sybase.pm
/usr/local/lib/perl/5.14.2/DBD/Sybase.pm
/usr/local/lib/perl/5.14.2/DBI/Sybase.pm
But when I try to run my script it returns an error on a line that calls 'if ($self->{handle} = DBI->connect('
# ./check_mssql_health --hostname <MSSQL_Server_IP> --username <SQL_User> --password <Pass> --mode connection-time
mode connection-time
CRITICAL - cannot connect to <MSSQL_Server_IP>. install_driver(Sybase) failed: Can't locate loadable object for module DBD::Sybase in #INC (#INC contains: . /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl) at (eval 10) line 3
Compilation failed in require at (eval 10) line 3.
Perhaps a module that DBD::Sybase requires hasn't been fully installed
at ./check_mssql_health line 3192
I've already spent a lot of time scavenging posts but I did not find a solution or at least one I could understand and Implement.

Answer 1

When I try to install DBD::Sybase CPAN tells me it's already installed:
That simply means it found a DBD/Sybase.pm. No tests are performed; the module isn't even loaded.
In an act of desperation I've copied the Sybase.pm to the DBD/
That's the cause of the error you're asking about. Perl is finding the .pm you copied over, but not the other files created as part of the installation process.
Delete the files you created[1], then install the module properly (e.g. using your system's package manager if it has one, or cpan DBD::Sybase if it doesn't).
You appear to have created at least the following files:
/usr/local/lib/perl/5.14.2/Sybase.pm
/usr/local/lib/perl/5.14.2/DBD/Sybase.pm
/usr/local/lib/perl/5.14.2/DBI/Sybase.pm

Answer 2

I got it working with a different setup.
Don't use DBD::Sybase, but install freetds, unixodbc, and then DBD::ODBC. In the freetds.conf file set the appropriate parameters. Mine looks like this
[myMSSL]
host = 111.22.33.44
port = 1433
tds version = 7.2
client charset = UTF-8
and /etc/odbc.ini
[mySQSL_mydb]
APP = unixodbc
Description = Database mydb on myMSSQL
Driver = TDSdriver
Server = myhost
Database = mydb
Port = 1433
#Trace = No
I think these are the packages that you need.
libdbd-freetds - Freetds database server driver for libdbi
tdsodbc -ODBC driver for connecting to MS SQL and Sybase SQL servers
freetds-bin - FreeTDS command-line utiliti
ALternatively, see also this post:
Using Ubuntu, how do I install DBD::Sybase from CPAN?
(and some others, e.g this one: Access SQL Server from Solaris)

Answer 3

I would try and install it via apt
sudo apt-get install libdbd-sybase-perl -y
I've found CPAN to sometimes miss dependencies.
