Base class package "Class::Singleton" is empty

[salaun-urennes1]

Version

6.2.36

Installation method

from sources

Actual behavior

The make command fails because the "Class::Singleton" CPAN module is required; see the output of the make below. This module is not provided by default on CentOS 7.5.

Expected behavior

The documentation https://sympa-community.github.io/manual/install/install-sympa-distribution-source.html should mention this requirement.

Hi @salaun-urennes1,
The PR above may avoid dependency to Class-Singleton during make.
Could you please check if it works as expected?

[xavierba]

This perl module is available in CentOS 7:

# yum provides 'perl(Class::Singleton)'
perl-Class-Singleton-1.4-14.el7.noarch : Implementation of a "Singleton" class
Repo        : base
Matched from:
Provides    : perl(Class::Singleton) = 1.4

On a side note, all modules needed for Sympa which are not available in CentOS are available in EPEL, I've been doing my best to get them in.
Also, there should be no need to build sympa from sources on Fedora or CentOS, I'm maintaining a COPR repo for it and plan to submit it to Fedora/EPEL.

Sorry for the shameless unsolicited spam :-)

This perl module is available in CentOS 7:

Yes, but Salaun is installing from source. According to procedure, dependent modules have not been installed.

[salaun-urennes1]

You're right, Soji, execution of make happens before sympa_wizard.pl takes care of missing CPAN module installation; that's the problem I had.

@ikedas I try to build from #437 but autoconf fails with the error below. What is the trick to run autoconf?

$ autoconf 
configure.ac:29: error: possibly undefined macro: AM_INIT_AUTOMAKE
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:31: error: possibly undefined macro: AM_PO_SUBDIRS
configure.ac:248: error: possibly undefined macro: AM_CONDITIONAL
configure.ac:353: error: possibly undefined macro: AM_PROG_CC_C_O

[ikedas]

@salaun-urennes1, I forgot to explain: As Makefile.am has been changed, you have to recreate makefiles. autoreconf -i may do the work.
(However, you may also need installing gettext-dev or such.)

[salaun-urennes1]

I had to install additional packages : yum install gettext-common-devel automake autoconf
After that autoreconf -i went well and configure an make too.

From my point of view, your PR fixes the issue; thanks

[ikedas]

I merged the PR. If you don't find any problem, please close this issue.
Thanks for reporting bug!
