I know I promised you a jabber server, but in the end it was not so easy and the entry would be perhaps too long, so let's start with simple stuff :-)
Note I am not a programmer, have no C skills, so there can be a glitch here and there, but in the end all steps below led me to something that worked. If you find something really nasty, please let me know.
I took most of the inspiration at Daniel Fišer's page on Asus WL-600g hacking and just tweaked it to suit my setup.
1. On a fresh Mandriva 2008.1 installation some of the necessary tools are missing. Install them as root:
2. Since Asus still did not release the sources for AM200g, I used the GPL setup provided for AM604g, which uses the same chipset and seems to be almost identical (it even comes in the same box, except for missing USB port and second antenna). Follow these steps to install it:
3. Not surprisingly, the AM604g source is just as broken as the AM600g one, so the same steps as described by Daniel need to be done:
4. Now you can try to build the firmware, just for fun:
The firmware is created in the
5. To prepare the environment, create a file containing:
and set the environment before doing anything else:
(yes, this is "dot space dot ...")
6. Let's proceed to the helloworld example. Create it's own folder:
and follow the steps described in the automake manual:

I took most of the inspiration at Daniel Fišer's page on Asus WL-600g hacking and just tweaked it to suit my setup.
1. On a fresh Mandriva 2008.1 installation some of the necessary tools are missing. Install them as root:
# urpmi make gcc autoconf automake
2. Since Asus still did not release the sources for AM200g, I used the GPL setup provided for AM604g, which uses the same chipset and seems to be almost identical (it even comes in the same box, except for missing USB port and second antenna). Follow these steps to install it:
$ wget http://dlsvr02.asus.com/pub/ASUS/Broadband/xDSL/GPL_AM604G_ForRussia.zip
$ unzip GPL_AM604G_ForRussia.zip
$ cd GPL_AM604G_ForRussia
$ tar xvf GENERIC_6348_WLAN_A34_3-06-02-01_GPL.tar.gz
$ su
# ./consumer_install
3. Not surprisingly, the AM604g source is just as broken as the AM600g one, so the same steps as described by Daniel need to be done:
# cd /opt/toolchains/uclibc-crosstools/bin
# for A in mips-linux-uclibc-* ; do
> ln -s ${A} mipsel-uclibc-${A#mips-linux-uclibc-}
> done
# cd /home/hajma/Documents/GPL_AM604G_ForRussia/GENERIC_6348_WLAN_A34_3-06-02-01
# wget http://daniel.fiser.cz/IT/asus_WL-600g/cur_menu.patch
# patch -p0 <cur_menu.patch
4. Now you can try to build the firmware, just for fun:
# make PROFILE=GENERIC_6348_WLAN_A34
The firmware is created in the
images directory. Since I have no replacement for the router, I'm not going to try it, although it might actually work.5. To prepare the environment, create a file containing:
$ cat environment
TOOLCHAINS_HOME=/opt/toolchains/uclibc-crosstools
export LIBS="-L${TOOLCHAINS_HOME}/lib/gcc/mips-linux/3.4.2"
export INCLUDES="-I${TOOLCHAINS_HOME}/include/c++/3.4.2 \
-I${TOOLCHAINS_HOME}/mips-linux/sys-include \
-I/home/hajma/Documents/GPL_AM604G_ForRussia/GENERIC_6348_WLAN_A34_3-06-02-01/kernel/linux/include"
export CFLAGS="${INCLUDES} ${LIBS} -static"
export LDFLAGS="-static"
export CC="${TOOLCHAINS_HOME}/bin/mipsel-uclibc-gcc"
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${TOOLCHAINS_HOME}/lib
export PATH="${PATH}:${TOOLCHAINS_HOME}/bin"
and set the environment before doing anything else:
# . ./environment
(yes, this is "dot space dot ...")
6. Let's proceed to the helloworld example. Create it's own folder:
mkdir /home/hajma/Documents/GPL_AM604G_ForRussia/GENERIC_6348_WLAN_A34_3-06-02-01/userapps/opensource/helloworld
and follow the steps described in the automake manual:
In addition to the manual's instructions, the details of host architecture must be provided when compiling for another platform. Also I set the prefix as the flash drive gets mounted as
Create the following files in an empty directory.Once you have these five files, it is time to run the Autotools to instantiate the build system. Do this using the
src/main.cis the source file for thehelloprogram. We
store it in thesrc/subdirectory, because later, when the package
evolves, it will ease the addition of aman/directory for man
pages, adata/directory for data files, etc.~/amhello % cat src/main.c
#include <config.h>
#include <stdio.h>
int
main (void)
{
puts ("Hello World!");
puts ("This is " PACKAGE_STRING ".");
return 0;
}READMEcontains some very limited documentation for our little
package.~/amhello % cat README
This is a demonstration package for GNU Automake.
Type `info Automake' to read the Automake manual.Makefile.amandsrc/Makefile.amcontain Automake
instructions for these two directories.~/amhello % cat src/Makefile.am
bin_PROGRAMS = hello
hello_SOURCES = main.c
~/amhello % cat Makefile.am
SUBDIRS = src
dist_doc_DATA = README- Finally,
configure.accontains Autoconf instructions to
create theconfigurescript.~/amhello % cat configure.ac
AC_INIT([amhello], [1.0], [bug-automake@gnu.org])
AM_INIT_AUTOMAKE([-Wall -Werror foreign])
AC_PROG_CC
AC_CONFIG_HEADERS([config.h])
AC_CONFIG_FILES([
Makefile
src/Makefile
])
AC_OUTPUTautoreconfcommand as follows:~/amhello % autoreconf --installAt this point the build system is complete.
configure.ac: installing `./install-sh'
configure.ac: installing `./missing'
src/Makefile.am: installing `./depcomp'
In addition to the three scripts mentioned in its output, you can see thatautoreconfcreated four other files:configure,config.h.in,Makefile.in, andsrc/Makefile.in. The latter three files are templates that will be adapted to the system byconfigureunder the namesconfig.h,Makefile, andsrc/Makefile. Let's do this:
/var/usb/usb_1: # ./configure --build=i686-pc-linux-gnu --host=mipsel-linux --target=mipsel-linux --prefix=/var/usb/usb_1/hello7. Optionally you can strip (remove all unnecessary bits) the binary:
# make
# make install
# cd /var/usb/usb_1/hello/bin8. Copy the files to the flash:
# /opt/toolchains/uclibc-crosstools/bin/mipsel-uclibc-strip -o hellostripped hello
# /home/hajma/Documents/squashfs2.0r2/squashfs-tools/mksquashfs /var/usb/usb_1 /tmp/dir.sqsh -be -noI -noD -noF9. Plug the flash drive to the router and verify all runs fine:
# dd if=/tmp/dir.sqsh of=/dev/sdb1
$ telnet 192.168.1.1Final note: if you get "hello: applet not found" instead, it means you somehow did not compile the program for correct platform and BusyBox was not able to execute it.
