Hi, I've worked on the patch originally proposed at http://sarovar.org/tracker/index.php?func=detail&aid=474&group_id=106&atid=495 I have rewritten the changes to the source files, so that they continue to use the xpdf code copy in the source tree and only use libpoppler if the compiler (or rather preprocessor) is called with -DPOPPLER. This version is attached. The harder part is the autoconf magic required for the switching, and not even writing autoconf (at least not yet), but rather incorporating the changes: On my system, "./reautoconf" does not work, instead complains: autoconf: invalid option -m I have $ autoconf --version autoconf (GNU Autoconf) 2.59 Written by David J. MacKenzie and Akim Demaille. Copyright (C) 2003 Free Software Foundation, Inc. Or is there a different way to regenerate configure after changes to its source files?
