Hi!

Its becoming a night mare installing RRDtool 1.4.7.
I did all the prerequisites.


cd /rrdtool-1.4.7

./configure
make
make install
ln -sf /opt/rrdtool-1.4.7 /opt/rrdtool
ln -sf /opt/rrdtool /usr/local/rrdtool

I have problem with RRDs.pm
perl -e "use RRDs; print $RRDs::VERSION;"
Can't locate RRDs.pm in @INC (@INC contains: /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 -e line 1.
BEGIN failed--compilation aborted at -e line 1.

If I locate:
locate RRDs.pm
/opt/rrdtool-1.4.7/bindings/perl-shared/RRDs.pm
/rrdtool-1.4.7/bindings/perl-shared/RRDs.pm
/rrdtool-1.4.7/bindings/perl-shared/blib/lib/RRDs.pm
/usr/local/lib/perl/5.10.1/x86_64-linux-thread-multi/RRDs.pm

Thanks

The compilation warnings are not a problem. Your issue is with the installation location.

You need to do a 'Site perl' install to install into your normal library locations, else it will go into a subdir under whatever install directory you specified. You've installed the Perl libraries under /opt/rrdtool/lib

Make sure you either have the location of RRDs.pm added to your perl module path, or else copy the relevant files to your relevant directory.

The librrd.so also needs to be in your LD_LIBRARY_PATH. Under Redhat, you can add a file /etc/ld.so.conf.d/rrdtool.conf containing the line '/opt/rrdtool/lib' to make this work.

Hi Steve!

Thanks alot for your reply.

I have create symbolic link
rrdtool -> /opt/rrdtool

so i have my rrdtool under

/usr/local/rrdtool

I was reading one of the post on:
http://martybugs.net/linux/rrdtool/
I can see the make site-perl-install but I am not sure where to run this so that it will automatically adjust the path required for perl.

I built the package again and now its.
Can't load '/usr/local/lib64/perl5/auto/RRDs/RRDs.so' for module RRDs: librrd.so.4: cannot open shared object file: No such file or directory at /usr/lib64/perl5/DynaLoader.pm line 200.

Compilation failed in require at -e line 1.
BEGIN failed--compilation aborted at -e line 1.

Thanks.

I tried the command below

yum install perl-Log-Log4perl-RRDs.noarch


Now i cant see any error if the run perl -e "use RRDs; print $RRDs::VERSION;"

I guess now the problem is solved.

Thanks
