build.sh editieren
wichtig ist das "ccache\ "

#! /bin/sh

make CROSS_COMPILE=mipsel-linux- CC=ccache\ mipsel-linux-gcc

madwifi.stripped

  • build.sh
#!/bin/sh

make TARGET=mips-le-elf KERNELPATH=$HOME/projects/brn/madmax/mips/kernel CC=ccache\ mipsel-linux-gcc

Click Kernelmodul bauen

  • Kernel kompilieren (build.sh)
  • Click kompilieren (erst conf_mips.sh, Warning ignorieren, cd linuxmodule/, make)
  • im Verzeichnis linuxmodule: build.sh editieren
#! /bin/sh

make TARGET=mips-le-elf CROSS_COMPILE=mipsel-linux- CC=ccache\ mipsel-linux-gcc

Click Modular Router

How to (temporarily) set up a SDP independent from the running one

  • First build everything for the new SDP. To do so, follow Bernhard's description, BUT there are two important differences:
    • Change BRN_NEIGHBOR_BEACON_MAGIC in <YOUR_BUILD_DIR>/click/include/clicknet/brn.h to a unique value. (Otherwise there will be problems with an existing SDP!)
    • Don't deploy your new package in the last step
  • Then the following has to be done for every node that is part of the new SDP infrastructure

Put the new software onto the WGT

scp -r <YOUR_BUILD_DIR>/sdp/package/library/0 root@<wgt_to_be_changed>:/tmp/sdp/library/

Then telnet to the WGT and execute the following commands

killall S90sdp
/usr/sbin/rcclick stop
killall click
echo 0 > /tmp/sdp/current_id
rm /tmp/sdp/current
ln -s /tmp/sdp/library/0 /tmp/sdp/current
/usr/sbin/rcclick start /tmp/sdp

Now the new SDP should be running and you should be able to deploy software on "your" nodes without affecting the other ones. To get rid of it and restore the original SDP (the SDP the rest of the testbed is running) just reboot the WGT.
