Goal
Concise statement of the overall goal of the project. Refine this initial statement to include: project deliverables (code, docs, testing), required/suggested methodology, standards of quality, possible goal extensions beyond the main objective.
Requirements
List the requirements and level of expertise you estimate are required by the developer tackling this project will have to have: Required level of programming language(s), specific areas of RTEMS or tools, level of familiarity with RTEMS, cross-development, GNU/Linux, etx., development/documentation/testing tools, mathematical/algorithmic background, other desirable skills.
Resources
Current RTEMS developers, papers, etc that may help you in this project.

A first stab at building Open LDAP
As the project progresses, you will need to add build instructions, etc and this page will evolve from a project description into a HOWTO.
I am building this package because it is simpler than the Apache Runtime, and so is a good way to gain needed experience. I started with using the RTEMS Addon Packages. How to use the RTEMS Addon Packages is outlined http://www.rtems.com/wiki/index.php/RTEMS_Add-On_Packages.
Makefile.openldap
I put the following in rtems-addon-packages/Makefile.openldap
# # Declare supported terminal types. # This value can be augmented/overridden by the site-configuration file #
include ../RTEMS_Makefiles/Makefile.common
# # The following will work only if you have the latest ncurses version # of infocmp installed before trying to build for an RTEMS target. # The cf_cv_type_of_bool hack works around a bug when configuring # for a cross-target. # all:
ac_cv_member_struct_msghdr_msg_control=no \ ac_cv_func_memcmp_working=yes \ ac_cv_func_initgroups=yes \ ac_cv_func_setuid=no \ ./configure \
--host=$(RTEMS_CPU)-rtems4.11 \ --prefix=$(exec_prefix) \ --libdir=$(exec_prefix)/$(RTEMS_BSP)/lib \ --includedir=$(exec_prefix)/$(RTEMS_BSP)/lib/include \ --without-tls \ --with-yielding_select=yes \ --disable-mdb \ --disable-hdb \ --disable-cleartext \ --disable-overlays \ --enable-proctitle \ --enable-debug \ --disable-shared
make make install
Next:
$ cd ~/rtems-addon-packages $ git clone git://git.openldap.org/openldap.git openldap $ cd openldap $ make -f RTEMS_Makefiles/Makefile.openldap
Note: Very insecure! But builds OK.
examples/openldap/BuildTests.sh
Currently openldap/BuilTests.sh builds the programs needed to run the tests, not the tests themselves...
Interestingly, I found it necessary to symbolically link the slapd-common header and source to each test, as well as the libutil library.
### examples/openldap/BuildTests.sh ### #!/bin/sh
set -x rm -f rtems-grub.cfg
SRCDIR=../../openldap/tests/progs ln -s $SRCDIR/slapd-common.h . ln -s $SRCDIR/slapd-common.c . ln -s $SRCDIR/../../libraries/liblutil/liblutil.a . for TEST in \
slapd-tester \ slapd-search \ slapd-read \ slapd-addel \ slapd-modrdn \ slapd-modify \ slapd-bind \ slapd-mtread \ ldif-filter
do
rm -f $TEST.c ln -s $SRCDIR/$TEST.c . make TEST=$TEST SRCDIR=$SRCDIR rm -f $TEST.c $TEST.o
done rm -f slapd-common.h rm -f slapd-common.c rm -f liblutil.a
# Generate rtems-grub.cfg
echo \# RTEMS Grub configuration for the >> rtems-grub.cfg
# The number of executables
echo set default = $(ls o-optimize | \ grep '\.'exe | wc -l) >> rtems-grub.cfg
# The menuentries ls o-optimize | \ grep '\.'exe | \ sed "s//menuentry \"RTEMS \-\" \{\n set root=(hd1,1)\n multiboo$ sed "s/\.exe/\.exe\n\}\n/" >> rtems-grub.cfg
examples/openldap/Makefile
I modified the rtems-addon-packages/examples/ncurses/Makefile to turn openldap programs used to test openldap into stand-alone executables.
I had to add slapd-common.c to the C_PIECES, and slapd-common.h to the headers.
Also, to link the liblutil.a convienience library, I had to add liblutil.a to C_O_FILES (it's an object file after-all :), I linked the ldap libraries using LD_LIBS, and increased the HeapSize? by a factor of ten (because it said networking required more -- online research is needed to get an exact size required).
Finally, it's worth noting the $(TEST) parameter is used to identify which test to build, and PGMS stands for programs.
# # $Id$ # # Templates/Makefile?.leaf # Template leaf node Makefile # SRCDIR=../../openldap/tests/progs
# C source names, if any, go here -- minus the .c C_PIECES=slapd-common $(TEST)

$(INSTALL_VARIANT) -m 555 ${PGMS} /usr/local/tftpboot/bootfiles/m68360/
To build the executables, I had to change some lines in /opt/rtems-4.11/make/leaf.cfg
define default-bsp-post-link
- $(NM) -g -n $@ > $(basename $@).num
- $(SIZE) $@ endef
define default-bsp-post-link + $(NM) -g -n $@.o > $(basename $@).num + $(SIZE) $@.o endef
Then, I ran BuildTests?.sh
~/rtems-addon-packages/examples/openldap$ ./BuildTests?.sh
Again this only built the programs used to run the tests as stand-alone executables...
Currently looking at how to build the tests -- they're in shell script :)... Hope this helps!
