Thanks for replying. While I still don't understand why only 2008q1-126 version of CS/MG toolchain doesn't compile kpdfview, while both earlier and later versions do, without touching the Makefile, your post gave me a lot of ideas to try (feel free to laugh if you find any of my actions particularly dumb).

I took a look inside your version of Makefile for kpdfview (actually, a diff file). I don't know why you made so many changes to it. KPDFView compiles with default Makefile without problems if I use either arm-kindle-linux-gnueabi from x-tools-glibc2.5-gcc4.2.4.tar.gz or arm-none-linux-gnueabi from CS/MG 2007q3-51, and they both work on kindle. I can only asume that you made a newer arm-kindle-linux-gnueabi, and that it was needed in your version.

I first tried simpler approach: I changed default Makefile like this:

Code:
-CFLAGS:=-O3 $(SYSROOT)
-CXXFLAGS:=-O3 $(SYSROOT)
+CFLAGS:=-O3 -fno-stack-protector -U_FORTIFY_SOURCE $(SYSROOT)
+CXXFLAGS:=-O3 -fno-stack-protector -U_FORTIFY_SOURCE $(SYSROOT)
and tried compiling it using CS/MG 2012.03, hoping it will make it work on kindle. It compiled without errors, but it didn't work on kindle. Then I changed last line to:

Code:
CXXFLAGS:=-O3 -fno-stack-protector -U_FORTIFY_SOURCE -fno-use-cxa-atexit $(SYSROOT)
Again, compiled ok, but didn't work on kindle. Then I put in all your changes from the patch file, keeping only HOST:=arm-none-linux-gnueabi unchanged, since I used that compiler. Again, same results. It compiled, but didn't work on kindle.

I reverted back to original Makefile, then went to my kindle, and typed:

$ tar -cf lib.tar /lib
$ tar -cf usrlib.tar /usr/lib

I transfered those files to PC, and unpacked them under /usr/local/k3/sysroot. I typed:
Code:
export SYSROOT=/usr/local/k3/sysroot
and tried compiling it again. This time it didn't compile.

Code:
arm-none-linux-gnueabi-gcc: warning: /usr/local/k3/sysroot: linker input file unused because linking not done
AR        libluajit.a
CC        luajit.o
arm-none-linux-gnueabi-gcc: warning: /usr/local/k3/sysroot: linker input file unused because linking not done
BUILDVM   ../lib/vmdef.lua
DYNLINK   libluajit.so
/usr/local/k3/sysroot: file not recognized: Is a directory
collect2: ld returned 1 exit status
make[2]: *** [libluajit.so] Error 1
make[2]: Leaving directory `/home/kai771/kindlepdfviewer/luajit-2.0/src'
make[1]: *** [default] Error 2
make[1]: Leaving directory `/home/kai771/kindlepdfviewer/luajit-2.0'
make: *** [luajit-2.0/src/libluajit.a] Error 2
This didn't surprise me. I wasn't really expecting it to work. So I deleted /usr/local/k3/sysroot, and copied sysroot folder from x-tools-glibc2.5-gcc4.2.4.tar.gz at the same place. I tried compiling again, and I got the same result as above.

There are still things I need to read and try, but if someone is willing to help me save time, please do so. The goal is to make kpdfview compile with CS/MG 2012.03 and work on kindle. I have no other reason for doing this except curiosity, so if you're busy, please just ignore this.

Oh, and btw, I updated the guide to include instructions for CS/MG 2007q3.
