Upgrading mtd-utils in uClinux.

Linux-mtd,
I am attempting to compile the latest mtd-utils into uClinux's distribution dated 2006-08-03. After some unsuccessful attempts I found the new mtd-utils needed an updated zlib. I successfully upgraded to zlib version 1.2.3 inside uClinux-dist/lib/zlib. I now have that compiling and still am not getting anywhere with compiling the mtd-utils. I dropped the latest mtd-utils code into the directory uClinux-dist/user/mtd-utils. I have observed the Makefiles between the new updated mtd-utils and the old uClinux-dist/user/mtd-utils/Makefile are VERY different. I tried to use the old Makefile as a template to build the new code and it still is not compiling. What is the correct method of upgrading mtd-utils? It shouldn't be as difficult to upgrade some code in user space as I am making it. I feel like I must be going about this the wrong way. Are there any pointers, tips, or recommendations to get me going in the right direction?

Thanks,
Glen Johnson

Unless someone here has had this specific problem, some form of output from the compilation indicating what is going wrong would be helpful.

Yes, of course. I have a couple more direct question. First, I found the mtd-utils code is not properly using zlib.

make[3]: *** [mkfs.jffs2] Error 1

The warning: .rodata section contains relocations is printed and it appears all other attempts to use libz.a are dropped. I Googled this warning and there were a couple of places where it mentioned configure.in. Is this the real problem? If so how can it be fixed, not familiar with autoconf)?

Secondly, once I get the code to compile it appears I still need to add a section to the Makefile to install the files into the romfs image. Can I just pull this out of the old mtd-utils/Makefile or what? Suggestion's/recommendations?
Thanks,
Glen Johnson

No '-lz' on this command line -- you're not actually asking it to link against zlib. Thus is doesn't find any of zlib's symbols.

I've no idea what this is about. Perhaps the function pointers in the jffs2_zlib_comp compressor structure?

mkfs.jffs2 builds fine for me for FR-V uClinux, although that's ELF-FDPIC not flat. Are the relocations in .rodata actually a problem? Doesn't m68k have ELF-FDPIC yet?

Something wrong with 'make DESTDIR=/foo install' ?

Yes, it appears to. When I try to execute mkfs.jffs2 on the host system I get the following error.
BINFMT_FLAT: reloc outside program 0x54e20000 (0 - 0xf57f4/0x11ec0), killing mkfs.jffs2!
SIGSEGV

I have the uClinux distribution dated 2006-08-03. I did a grep -r ELF-FDPID ./ and found it mentioned in the code for the Fujitsu FRV processor and nothing else. Someone told me he thought it did. But I do not see it in the code. The compiler does appear to have elf support according to this line in the output of make, ARCH=m68knommu CROSS_COMPILE=m68k-elf- this however is Not ELF-FDPIC.
Is there a better way to tell if m68knommu supports ELF-FDPIC?
