Comment 5 for bug 1276871

No, Adobe pdf isn't on the list in File->Open dialog.

$HOME/.config/inkscape/extension-errors file has this in it:
Extension "EPS Input" failed to load because a dependency was not met.
Dependency:
  type: extension
  location: path
  string: org.inkscape.input.pdf
<...>
Extension "PostScript Input" failed to load because a dependency was not met.
Dependency:

  location: path
  string: org.inkscape.input.pdf

In the inkscape port, POPPLER option is "on" for my build. This option turns on the dependency on libpoppler-glib.so, and also adds the configure option --enable-poppler-cairo.

However, config.log has this:
configure:13806: WARNING: unrecognized options: --enable-poppler-cairo
configure doesn't support --enable-poppler-cairo option.

configure.ac defines this option:
AC_ARG_ENABLE(poppler-cairo,
        AC_HELP_STRING([--enable-poppler-cairo], [Enable libpoppler-cairo for rendering PDF preview]),
        [enable_poppler_cairo=$enableval], [enable_poppler_cairo=yes])
However, it is missing from the configure file. This looks wrong. That's why configure rejects it.

Can you tell me, why inkscape-0.48.4 distributive doesn't have this option in configure file, and has it in configure.ac?
