Etch and Perl

Etch is written in Perl and has the following requirements for your Perl installation:

• Perl >= 5.6
• CPAN modules:
  • XML::LibXML
  • XML::SAX

The XML modules require the libxml2 library.

By default etch is configured to use /usr/etch/bin/perl. If your system comes with a recent version of Perl or you have a copy of Perl already installed somewhere that you'd like to use then you can just symlink /usr/etch/bin/perl to that location. For example, the sample RPM spec file that we provide for Red Hat systems links /usr/etch/bin/perl to /usr/bin/perl.

Red Hat

All versions of Red Hat Enterprise Linux and Fedora Core includes RPMs of all of the software that etch requires. Install the necessary RPMs with yum or up2date:

yum install perl-XML-LibXML perl-XML-SAX rsync rcs mktemp

up2date -i perl-XML-LibXML perl-XML-SAX rsync rcs mktemp

Make sure to symlink /usr/etch/bin/perl to /usr/bin/perl.

Solaris

Blastwave

The blastwave.org Community SoftWare (CSW) project is our recommended source for etch's dependancies on Solaris. Start by following their HOWTO, which will get their pkg-get installation tool installed and configured on your machine. Then use pkg-get to install the following packages:

pkg-get -i pm_xmllibxml pm_xmlsax rsync rcs mktemp

Make sure to symlink /usr/etch/bin/perl to /opt/csw/bin/perl.

Sunfreeware

Alternately you might be using Perl from Sunfreeware. You'll also need their libxml2, rsync, rcs and mktemp packages. The necessary Perl modules will then need to be installed using your favorite method of installing CPAN modules, since Sunfreeware doesn't provide packages of CPAN modules. If you don't have a favorite method this should do the trick:

/usr/local/bin/perl -MCPAN -e 'install XML::LibXML; install XML::SAX'

Make sure to symlink /usr/etch/bin/perl to /usr/local/bin/perl.

FreeBSD

We recommend you use the FreeBSD ports or package trees to install Perl and the other dependancies from the ports system into /usr/local. The easiest way to install the necessary packages is with the following command, which will fetch everything from the FreeBSD FTP site:

pkg_add -r perl p5-XML-LibXML p5-XML-SAX rsync

Make sure to symlink /usr/etch/bin/perl to /usr/local/bin/perl.
