Question

I'm trying to install perl modules via cpanm inside conda environment with perl installed. The conda environment was build with following definition: 

name: perl_env

channels:
  - bioconda
  - conda-forge
  - defaults

dependencies:
  - perl=5.26
  - perl-app-cpanminus
  - perl-local-lib
  - gcc_impl_linux-64
  - gxx_linux-64
  - openmpi=4.1.0

The environment results with the following packages installed:

The same happens while installing different perl packages (DBI). I am not really able to overcome this error so I strongly ask for help, thank you in advice.

Yes, you are right! Within the activate conda perl_env I got strange behaviours. If I type:

which perl

/usr/bin/perl

if I type:

command -v perl

/igatech/rd/dev/snakemake-workflows/annotation-maker_p/tests/snakemake/.snakemake/conda/4520f5b9/bin/perl

or

whereis perl

perl: /usr/bin/perl /igatech/rd/dev/snakemake-workflows/annotation-maker_p/tests/snakemake/.snakemake/conda/4520f5b9/bin/perl /usr/share/man/man1/perl.1.gz

If I do:

perl --version

This is perl 5, version 26, subversion 2 (v5.26.2) built for x86_64-linux-thread-multi

Copyright 1987-2018, Larry Wall
...

or If I do:

/usr/bin/perl --version

This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 40 registered patches, see perl -V for more detail)

Copyright 1987-2012, Larry Wall
...

To be honest it's known that in my system which command behaves strangely. I wouldn't like that this was the cause of the problem...

PS: conda env 4520f5b9 is same as perl_env

I can try answer the first part of the question: How to use the correct perl when installing packages in the conda environment. I am on Ubuntu 20.04:

  • First I installed Anaconda into /home/hakon/anaconda3
  • Then I created a test environment:
$ conda create --name perl_test
$ conda activate perl_test
  • Installed perl 5.26.2 into the environment:
$ conda install -c anaconda perl
  • Initialized cpan (this assumes that I did not have any previous cpan configuration ( ~/.cpan/ ) and local lib ( ~/perl5/ ) set up in my home directory). Choose the local::lib option below:
$ cpan
Loading internal null logger. Install Log::Log4perl for logging messages
Sorry, we have to rerun the configuration dialog for CPAN.pm due to
some missing parameters. Configuration will be written to
 <</home/hakon/.cpan/CPAN/MyConfig.pm>>


CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible automatically? [yes] 

 <install_help>

Warning: You do not have write permission for Perl library directories.

To install modules, you need to configure a local Perl library directory or
escalate your privileges.  CPAN can help you by bootstrapping the local::lib
module or by configuring itself to use 'sudo' (if available).  You may also
resolve this problem manually if you need to customize your setup.

What approach do you want?  (Choose 'local::lib', 'sudo' or 'manual')
 [local::lib]           


Autoconfiguration complete.

local::lib is installed. You must now add the following environment variables
to your shell configuration files (or registry, if you are on Windows) and
then restart your command line shell and CPAN before installing modules:

PATH="/home/hakon/perl5/bin${PATH:+:${PATH}}"; export PATH;
PERL5LIB="/home/hakon/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}"; export PERL5LIB;
PERL_LOCAL_LIB_ROOT="/home/hakon/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB_ROOT}}"; export PERL_LOCAL_LIB_ROOT;
PERL_MB_OPT="--install_base \"/home/hakon/perl5\""; export PERL_MB_OPT;
PERL_MM_OPT="INSTALL_BASE=/home/hakon/perl5"; export PERL_MM_OPT;

Would you like me to append that to /home/hakon/.bashrc now? [yes] no

Note that I answered "no" on the previous question.

  • Now I copied the generated local lib to the conda environment:
$ echo $CONDA_PREFIX
/home/hakon/anaconda3/envs/perl_test
$ mv ~/perl5 /home/hakon/anaconda3/envs/perl_test
  • Then configured the conda environment so that local lib is activated when the environment is activated:
$ mkdir -p $CONDA_PREFIX/etc/conda/activate.d
$ vim $CONDA_PREFIX/etc/conda/activate.d/env_vars.sh
  • Add the following content to the previous env_vars.sh file:
export PATH="$CONDA_PREFIX/perl5/bin${PATH:+:${PATH}}"
export PERL5LIB="$CONDA_PREFIX/perl5/lib/perl5${PERL5LIB:+:${PERL5LIB}}";
export PERL_LOCAL_LIB_ROOT="$CONDA_PREFIX/perl5${PERL_LOCAL_LIB_ROOT:+:${PERL_LOCAL_LIB_ROOT}}";
export PERL_MB_OPT="--install_base \"$CONDA_PREFIX/perl5\""
export PERL_MM_OPT="INSTALL_BASE=$CONDA_PREFIX/perl5"
  • Restart the conda environment to load the above environment variables:
$ conda deactivate
$ conda activate perl_test
  • Install cpanm
$ cpan App::cpanminus
  • Install the module:
$ which cpanm

So this fails. If I try to install the failing module Acme::Damn manually:

$ wget https://cpan.metacpan.org/authors/id/I/IB/IBB/Acme-Damn-0.08.tar.gz
$ tar zxvf Acme-Damn-0.08.tar.gz
$ cd Acme-Damn-0.08
$ perl Makefile.PL

It shows that make tries to use a nonexistent C compiler:

 /tmp/build/80754af9/perl_1527832170752/_build_env/bin/x86_64-conda_cos6-linux-gnu-gcc

A clue to why this happens is given by the perl configuration data for cc : 

$ perl -V | grep cc=./
    cc='/tmp/build/80754af9/perl_1527832170752/_build_env/bin/x86_64-conda_cos6-linux-gnu-gcc'

I think that when perl tries to compile an XS module it uses the same C compiler that was used to compile perl with. But in this case that compiler does not exist any more, since conda installed (downloaded) a pre-compiled perl (so the cc variable refers to a compiler on another machine, the machine that was used to compile perl with)

Probably this means that you cannot (should not) install XS modules with a downloaded precompiled perl. I would recommend that you build perl from source on the same machine instead.

Edit

My bad, it is actually possible to install the same compiler that was used to build perl by running:

$ conda install -c anaconda gcc_linux-64
$ which  x86_64-conda_cos6-linux-gnu-gcc
/home/hakon/anaconda3/envs/perl_test/bin/x86_64-conda_cos6-linux-gnu-gcc

But still I am not able to make perl Makefile.PL use that version yet..

Edit 2

Added follow-up question .

Edit 3

After applying the patch in the follow-up question , I was able to install the module:
