# notes for building qt-embedded & opie against uClibc 0.9.16 for the 
# Casio Cassiopeia BE-300 PDA and the linux4.be project
# see http://www.linux4.be for more info
# I have no idea if any of this is correct I was unable to test it...
# the final binaries are too large to fit in a ramdisk the BE can handle
# and as of 12/03/2002 the kernel does not support the cf slot or NAND
# "Kernel panic: Out of memory and no killable processes..."

# make install requires some hacking... since we are not installing on a real
# system ldconfig can not be called so we have to edit the Makefiles in the
# various lib dirs libpam, libpamc, libpam_misc and remove refereces to
# $(LDCONFIG)
# we also need to edit the top level Make.Rules because the use of $(FAKEROOT)
# is inconsistant. change FAKEROOT= to FAKEROOT=${prefix}
# this causes another problem... some things are installed doublely deep into
# the prefix dir... for example if --prefix=/home/johnbot/tmp then some files
# are installed in $prefix and others are installed in $prefix/$prefix just
# move the files in $prefix/$prefix to $prefix (mv $prefix/$prefix $prefix)

# *** OPIE CVS NOTES ***

./configure -xplatform mips

# lots of stuff does not compile
# some is fixable some not just skip stuff for now
# most of multimedia apps will not work cause i couldn't get xinelib
# to build...
# there is a time struct error that can be hacked with constants
# in noncore/mail/libmail/miscfunctions.cpp
# mainly we need the stuff in core/launcher and libopie built
# core/launcher/launcherview.cpp needs 
# #include <qstdlib> changed to #include <stdlib.h>
# 
# copy all the libs and includes from jpeg6b, e2fsprogs, & PAM to 
# $QTDIR/lib and $QTDIR/include so opie can find them
