Works for me, but I also had to change this: diff --git a/config.h.cmake b/config.h.cmake index c3b30db..a8a0c46 100644 --- a/config.h.cmake +++ b/config.h.cmake @@ -222,7 +222,7 @@ #endif /* Number of bits in a file offset, on hosts where this is settable. */ -/* #undef _FILE_OFFSET_BITS */ +#cmakedefine _FILE_OFFSET_BITS @_FILE_OFFSET_BITS@ /* Define to 1 to make fseeko visible on some hosts (e.g. glibc 2.2). */ /* #undef _LARGEFILE_SOURCE */ Tested on my laptop (Linux/x86 32 bit). I'll test on MacOS/ppc64 when I get back home. > Cheers, > Albert > > > Fabio > > > > _______________________________________________ > > poppler mailing list > > [email protected] > > http://lists.freedesktop.org/mailman/listinfo/poppler -- Fabio _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
