Re: [microblaze-uclinux] Compiliation Error

["Stephen Craven" <scraven@xxxxxx>]

All,

I apologize for my ignorance -- I am new to the world of kernel compiling.
However, I have followed the posted instructions
(http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/Documentation/index.htm
l) to the letter and, even after applying the provided patch I still receive
compilation errors.

Using the most up-to-date CVS version of the sources and using only the
default options (mbvanilla_net, all defaults) I receive a 'make' error:
http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2005/02/msg00013.html

When I apply the patch from Yashi
(http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2005/02/msg0
0014.html) or use the previous kernel version
(http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2005/02/msg0
0020.html) as directed by Dr. Williams, I receive a different error
complaining about a missing crypt_old library:
http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2005/02/msg00021.html

And indeed this library, crypt_old, has not been created. When I go into the
lib/libcrypt_old directory and do a 'make' to create the missing library,
the kernel compilation returns yet another error -- segmentation fault,
actually:

mb-gcc  -Os -g -fomit-frame-pointer -fno-common -Wall   -mno-xl-soft-mul -mx
l-barrel-shift -mno-xl-soft-div -Dlinux -D__linux__ -Dunix -D__uClinux__ -DE

/usr/local/microblaze-elf-tools//bin/mb-ld: line 156: 11225 Segmentation
fault      $LINKER -r -d -o "$OFILE.elf2flt" $ARG1

I grabbed everything today, including the MB toolchain.  Do I need another
patch?  Should I be creating the crypt_old library?

Much thanks!
