Hi Peter, hi all,

I cannot contribute much, but here it is

It is not "we", the poppler guys are others, we just use the stuff.

I guess anything is fine that makes it possible to show that the binary
has been compiled with poppler and not xpdf.

If there is a define that can be checked for it is probably only a bit
of coding, I have:
luatexextra.in:
-#define BANNER "This is LuaTeX, Version LUATEX-VERSION"
+#define BANNER "This is LuaTeX using libpoppler, Version LUATEX-VERSION"

uatexdir/utils/utils.c
-                    "Compiled with xpdf version %s\n",
+                    "Compiled with poppler version %s\n",

Here a poppler version number would be nice. I used pkg-config to get
it.

? Not that I have used it ever.

I would say we stay with the latest one, so 0.10. I have patches for all
poppler versions down to 0.4 or so, but they are getting messier and
messier the earlier a poppler version we try.

No, at least 0.10 I would say.

So I do.

When that is done I can contribute some patches for luatex/xetex/pdftex
so that it compiles again.

Again, thanks a lot and all the best
