Mike,

thanks for the suggestions. I still get a segmentation fault. This is getting frustrating... I have been working on this for over a week and have got nowhere. Do you have a realease (uClinux) and toolchain that works? If you do, please send me an e-mail to apco25@yahoo.com and I can give you details of how to get it to me. As you know I am new to this. I am not apposed to doing research and reading. If you or someone out there has some good material on this sort of thing to troubleshoot this that would be great, I just don't know where to look. What can I read to figure out what all this stuff is? Where to begin? It seems like you and I are the only ones having trouble with this... Seems like others get it to build somehow. I have built other designs with this release (uClinux) for motorola and such and it works fine with my setup.

Thanks again,

Greg

Greg,

I've only now gotten back to looking at this. The segmentation fault seems
to have been the result of the error at the end of the make for
libcrypt_old.a. When running the make manually ${RANLIB} was not defined.
Manually running "ranlib libcrypt_old.a" seemed to fix the segmentation
fault.

But that wasn't the end of the problems. Next were a missing zlib.h and then
a missing libz.a.

It seems like all the problems trace back to the two targets: jffs and
jffs2. Rather than sort out why those were broken, I simply removed them by
commenting them out of the "TARGETS =" line of
uClinux-dist/user/mtd-utils/Makefile. This may be a known problem -- I
haven't checked yet.

Anyway, with them gone the make of the kernel completed. I don't know yet if
the result works.

Mike
