Seems like he's switched to summon

boop 2013-04-16 gunnarhenne [r57] Anpassung an summon ARM toolchain
svn checkout svn://svn.code.sf.net/p/boopfirmware/code/ boopfirmware-code
I just compiled the trunk with the attached Makefile & linker-file.
I used this "arm launchpad" compiler , a newer one might also work
gcc version 4.7.4 20130913 (release) [ARM/embedded-4_7-branch revision 202601] (GNU Tools for ARM Embedded Processors)
It's strange that the makefile creator keeps using ld for linking and not gcc
That is NOT the recommended way , and that's why he has to specify those libraries manually.
I have corrected to use gcc as linker
Ps: You have to adapt this line in the makefile , to point on there you have installed the arm-gcc toolchain
