I can no longer compile documents with the biblatex-philosophy style for the citations and references.

The document does not compile at all, and I get the following message

Undefined control sequence \ifblx@load@version@legacy

and several

Illegal parameter number in definition of \blx@defformat@d.

I have tried googling the problem, and only come across something about a year ago relating to a texlive or biblatex update.

Here is a minimal example that fails to compile:

\documentclass{article}
\usepackage[backend=biber,citestyle=philosophy-classic,bibstyle=philosophy-classic]{biblatex}
%   \bibliography{References.bib}
\begin{document}
% \maketitle
Text.
\end{document}

How can I fix this to compile documents with the biblatex-philosophy style?

  • Works fine for me in a current texlive 2016 and File: philosophy-classic.bbx 2016/11/26 v1.9 A set of styles for biblatex. Is your system up-to-date? – Ulrike Fischer Jan 24 '17 at 14:55
  • I can confirm that version 2016/11/26 v1.9 of philosophy-classic runs in your MWE as well as an extended document without problems together with biblatex 3.7. I strongly suspect that you are using an outdated version of biblatex-philsophy, you need to update the package to the current version either with tlmgr (TeX live) or the 'MikTeX Update' tool in both Admin and User mode. – moewe Jan 24 '17 at 17:21

    Yes, that was the problem was an old version of biblatex-philosophy. I'm using openSUSE Tumbleweed, so assumed that all texlive packages are up to date, but biblatex-philosophy is still at v1.3! Many thanks. – Tudor Protopopescu Jan 28 '17 at 09:45

The problem is no longer present in the current version of biblatex-philosophy (1.9 dated 2016-11-26). So you should update the package in your TeX distribution. When you update the package, make sure to update the biblatex package and Biber along with biblatex-philosophy to avoid version conflicts.

\ifblx@load@version@legacy is an outdated and no longer supported way to check if BibTeX or Biber is used as backend. See also Impossible to build document with biblatex-chicago.

The error \blx@defformat@d appears if one needs pre-3.3 code to modify the name format with biblatex version >=3.3. See Biblatex 3.3 name formatting.
