Download custom makefiles
-------------------------

   Get the files from http://josefsson.org/uclinux/old/

   Apply it as follows:

...........
cd uClinux/lib/
wget -O libgpg-error-1.5/config.h http://josefsson.org/uclinux/old/libgpg-error.configh
wget -O libgpg-error-1.5/makefile http://josefsson.org/uclinux/old/libgpg-error.mk
wget -O libgcrypt-1.2.4/config.h http://josefsson.org/uclinux/old/libgcrypt.configh
wget -O libgcrypt-1.2.4/makefile http://josefsson.org/uclinux/old/libgcrypt.mk
wget -O libtasn1-0.3.10/config.h http://josefsson.org/uclinux/old/libtasn1.configh
wget -O libtasn1-0.3.10/makefile http://josefsson.org/uclinux/old/libtasn1.mk
wget -O gnutls-1.6.3/config.h http://josefsson.org/uclinux/old/gnutls.configh
wget -O gnutls-1.6.3/makefile http://josefsson.org/uclinux/old/gnutls.mk
wget -O gsasl-0.2.20/config.h http://josefsson.org/uclinux/old/gsasl.configh
wget -O gsasl-0.2.20/makefile http://josefsson.org/uclinux/old/gsasl.mk
...........

Note that the modified config.h files uses the #include <endian.h> to
find out the endian-ness of the platform.  If that header file is
unavailable or incorrect, you'll have to modify endian-ness yourself
by setting WORDS_BIGENDIAN correctly.  Remember that x86 is little
endian, and many other platforms are big endian.  Use 'make check' in
libgcrypt to verify that it works correctly.

Adapt lib/Makefile
------------------

   Search for the following lines in lib/Makefile:

.......
# And build libraries in the prop directory last
dir_y += $(ROOTDIR)/prop
.......

   Add the following statements _before_ those two lines:

.......
dir_y += libtasn1-0.3.10
dir_y += libgpg-error-1.5
dir_y += libgcrypt-1.2.4
dir_y += gnutls-1.6.3
dir_y += gsasl-0.2.20
.......


   Search for the following line in lib/Makefile:

.......
LINKLIBS=\
.......

   Add the following lines _after_ that line:

.......
    $(ROOTDIR)/lib/libtasn1-0.3.10/lib/*.a \
    $(ROOTDIR)/lib/libtasn1-0.3.10/lib/libtasn1.h \
    $(ROOTDIR)/lib/libgpg-error-1.5/src/*.a \
    $(ROOTDIR)/lib/libgpg-error-1.5/src/gpg-error.h \
    $(ROOTDIR)/lib/libgcrypt-1.2.4/src/*.a \
    $(ROOTDIR)/lib/libgcrypt-1.2.4/src/gcrypt.h \
    $(ROOTDIR)/lib/libgcrypt-1.2.4/src/gcrypt-module.h \
    $(ROOTDIR)/lib/gnutls-1.6.3/lib/libgnutls.a \
    $(ROOTDIR)/lib/gnutls-1.6.3/includes/gnutls/compat.h \
    $(ROOTDIR)/lib/gnutls-1.6.3/includes/gnutls/gnutls.h \
    $(ROOTDIR)/lib/gnutls-1.6.3/includes/gnutls/pkcs12.h \
    $(ROOTDIR)/lib/gnutls-1.6.3/includes/gnutls/x509.h \
    $(ROOTDIR)/lib/gsasl-0.2.20/lib/src/*.a \
    $(ROOTDIR)/lib/gsasl-0.2.20/lib/src/gsasl.h \
.......

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

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

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

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

Finished
--------

The packages, more precisely the libraries and header files, should
now be available from:

...........
             uClinux-dist/lib/libgpg-error.a
             uClinux-dist/lib/libgcrypt.a
             uClinux-dist/lib/libtasn1.a
             uClinux-dist/lib/libgnutls.a
             uClinux-dist/lib/libgsasl.a
