Re: Obtaining perl-5.6.2 for modern Ubuntu

Hello, I managed to have perl 5.6 on Ubuntu 18.04.1. I'm doing 2 things :

Use patchperl (just mandatory when you want to build old perl on recent distributions)
Add the -lm to the cc -o miniperl ... (in the middle of the make step) - we add it through the configure script (-Alibs='-lm')

wget https://www.cpan.org/src/5.0/perl-5.6.2.tar.gz
tar xvzf perl-5.6.2.tar.gz
sudo cpanm Devel::PatchPerl
patchperl perl-5.6.2
cd perl-5.6.2
./Configure -des -Dprefix=/opt/perl5.6 -Aldflags='-lm'
make 
sudo make install
[download]

Hope it will help you (if you don't want to use perlbrew).

Rgds,

Thibault

I managed to have perl 5.6 on Ubuntu 18.04.1 Thanks for this - just the sort of approach I needed to see ! Nothing wrong with perlbrew's capability to build perl-5.6.2, but this approach makes the procedure clearer, and also saves me having to find out how to influence the Configure flags with perlbrew. Following those instructions, I built and installed a -Duselongdouble build of perl-5.6.2. (It failed only 2 tests of the test suite.) BTW, you missed out the `tar zxvf perl-5.6.2.tar.gz` step, which was enough to befuddle me for longer than I care to admit ;-) (I recommend that you correct that.) Cheers, Rob	[reply] [d/l]
