I try to compile a friends project and get the following error message:
! Package keyval Error: pdfa undefined.
See the keyval package documentation for explanation.
Type H <return> for immediate help.
...
l.2238 \ProcessKeyvalOptions{Hyp}
In this project there is no line 2238 and the package keyval
is not used either.
Same project can be compiled on other machines.
This happens when I use the package jheppub
, so a minimal working example would be:
\documentclass{article}
\usepackage{jheppub}

Package
hyperref
has introduced optionpdfa
in version 2008/04/19 v6.77r. If yourhyperref
version is older, then an update is needed to get the option.
