Description:
Installing for mysql-cluster-community-client requires perl-Class-MethodMaker, which is not available on CentOS7 by default. 

perl-Class-MethodMaker is available from EPEL.

The WB docs ( https://dev.mysql.com/doc/workbench/en/wb-installing-linux.html ) cover EPEL a bit, but I couldn't find anything related to NDB Cluster.

How to repeat:
Try to install mysql-cluster-community-client w/o external repositories enabled on OEL7/RHEL7/CentOS7.

Suggested fix:
Add a note to the MySQL Cluster Documentation about the requirement for EPEL/perl-Class-Methodmaker

Hi,

I do not think we should really document in mysql cluster documentation what each distro pack in to what repo. The RPM system properly handles the dependency resolution and it's up to system administrator to know where to find the dependencies.. in the case of MethodMaker the admin might chose to get it from EPEL but it might chose to get it from some other repo, we are not forcing any of those, just as long as MethodMaker is there.

kind regards

Ok, but in that case shouldn't one of the installation steps be 'Install Class::MethodMaker'?

Maybe just list is as a prerequisite for the installation procedure?

Hi,

I strongly disagree, as then it can be argued that you also need to have whole bunch of other libraries configured, installed the os etc etc .. It is assumed that installation is done by the system administrator (in case of RHEL/OL that's supported platform in this case) and every decent sysadmin will anyhow have EPEL installed, not to mention, will know how to install dependencies. 

To list "what dependencies exist" you have that all inside the RPM, don't see a point of listing them on the documentation page, and if you are going to satisfy them by turning on EPEL or some other repo, or you will install it trough CPAN and --nodeps install it is totally sysadmin's choice.

take care
Bogdan
