@Kai771: 2008q1-126 is a known 'bad' release, with a buggy GCC that throws ICE in a lot of known conditions
I tweaked it somewhat more extensively than needed because I'm using a 'bleeding-edge' TC that uses a vastly more recent GCC & glibc combo than what's used on the Kindle (and than the TC used by the devs), so I *need* some of this stuff to actually avoid pulling incompatible stuff from those newer versions
(most notably the glibc's fortify support, and gcc's stack smashing protection I mentioned in my previous message).
There's also a few changes related to building mupdf in release mode, not debug, and not breaking the build of stuff targeted at the host system because I have an ARM march in the default CFLAGS, which obviously my host's x86 GCC would throw a fit about
I could be wrong, because I'm always putting my minimal self-built system in the searchpaths (via CPPFLAGS & LDFLAGS), but I'm not sure kpdf actually needs anything out of its tree (other than a proper glibc TC), so, I personally don't tweak/set SYSROOT, and don't use stuff from the Kindle's FS or the tarball alluded to.
All that said, take a look at your binaries built with MG 2012.03 via readelf (especially the .gnu.version* sections, via readelf -V for example). That should give you a good hint of what's wrong (shouldn't pull anything more recent than glibc 2.5 & gcc 4.1).
EDIT: Well, the runtime error you get when running it on the Kindle helps, too, but readelf is faster/more detailed
Version needs section '.gnu.version_r' contains 6 entries:
