Introduction to biber

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

This package is known to build and work properly using an LFS-11.0 platform.

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/2021 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.

Recommended (required for the testsuite)



It is possible to install all missing dependencies automatically. You must first install Module-Build-0.4231 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:

tar -xf ../biblatex-3.16.tds.tgz -C /opt/texlive/2021/texmf-dist &&
texhash &&
./Build install

Command Explanations

tar -xf biblatex-3.16.tds.tar.gz -C /opt/texlive/2021/texmf-dist: this installs the new biblatex files over those installed by texlive.

texhash : this updates the file hash tables (otherwise known as the file name database).
