Introduction to biber

Biber is a BibTeX replacement for users of biblatex, written in Perl, with full Unicode support.



Development versions of BLFS may not build or run some packages properly if dependencies have been updated since the most recent stable versions of the book.

Package Information



If you have updated to a new release of texlive-source, biber and its perl dependencies are still present in /usr and do not need to be rebuilt. However, biblatex installs in /opt/texlive/2022 and does need to be reinstalled.

If you installed the above dependencies using the BLFS instructions for each of them, perl ./Build.PL will complain that Mozilla::CA is not installed, but that is not needed unless CPAN was used to install the modules. BLFS patches LWP::Protocol::https to use the system certificates, Mozilla::CA uses old certificates.

It is possible to install all missing dependencies automatically. You must first install Module-Build-0.4232 using automatic installation of perl modules. Then run perl ./Build.PL and when it prompts you, become the root user and run ./Build installdeps - this will use CPAN and as noted above it will use Mozilla::CA instead of using system certificates.

User Notes:

Installation of Biber

Install Biber by running the following commands:

perl ./Build.PL &&

To test the results, enter: ./Build test

Now, as the root user:

./Build install

The corresponding version of biblatex is a separate project. The tarball is pre-packaged for untarring into the texmf-dist directory. Install it as the root user:

tar -C $TEXLIVE_PREFIX/texmf-dist -xf ../biblatex-3.18b.tds.tgz
