Download patch

   Get it from http://josefsson.org/uclinux/

   This was written for the 20070607 version,
   SHA-1 01022c6fba6f9c480cb29ba35ba73bfbf2db3cdb.

   Apply it as follows:

   ...........
   $ patch -p 0 < 20070607.diff
   patching file uClinux-dist/config/Configure.help
   patching file uClinux-dist/config/config.in
   patching file uClinux-dist/lib/Makefile
   patching file uClinux-dist/lib/libgpg-error/makefile
   patching file uClinux-dist/lib/libgcrypt/makefile
   patching file uClinux-dist/lib/gnutls/makefile
   patching file uClinux-dist/lib/gsasl/makefile
   $
   ...........

Build uClinux
-------------

   ...........
   $ cd uClinux-dist
   $ make menuconfig
   ...........

   I changed the kernel to 'linux-2.4' and CPU to Freescale/M5407C3.

   Be sure to toggle 'Customize Vendor/User Settings' under
   'Kernel/Library/Defaults Selection' in the first dialog.

   Be sure to toggle libgpg-error, libgcrypt, gnutls and/or gsasl under
   'Library Configuration' in the second dialog.

   ...........
   $ make dep
   $ make
   ...........

   If you get build failures during ./configure of gnutls or gsasl
   related to missing 'libgcrypt-config' you need to do:

   ...........
   $ cd uClinux-dist/lib/libgcrypt/inst/bin
   $ ln -s m68k-elf-linux-libgcrypt-config libgcrypt-config
   ...........

Finished
--------

The packages, including in particular the libraries, should now be
available from:

   ...........
             uClinux-dist/lib/libgpg-error/inst/
             uClinux-dist/lib/libgcrypt/inst/
             uClinux-dist/lib/gnutls/inst/
             uClinux-dist/lib/gsasl/inst/
