Hi Dario, i suggest you to download the last Sylvain's burst_ind, because is improved of some features and patch it manually with Nohl's patch. Then you will be able to dump the bursts using ccch_scan, instead of layer23. Cheers, Luca > Can someone drive me to the right direction?

There is nothing wrong with Ubuntu 11.10 (11.04...) but apparently you changed more than jut 11.10 -> 11.04. From the little information you provide one can see you at least changed the place where you keep the sourcecode. So please keep your environment stable because otherwise you wasted the time of the ones that were kind enough to respond. So the path to success: 1.) Think, try to understand what happens 2.) Provide context when you are writing an email, what do you do, why do you do this? what you think should happen 3.) include complete output.... In this specific case: Find where the sourcecode of msgb_free is (the answer will be msgb.c), find the msgb.o (compiled object file) that was compiled for ARM. Look if there is a msgb_free in it (objdump,nm..) or if there is something wrong with this file (ls, file, readelf). My guess is that you did something funny during compile and ended up with a zero byte msgb.o. cheers holger

Compling pb with Ubuntu 11.04 64 bits

Hi all I'll upgrade a Ubuntu 11.04 64 bits to 11.10 and it seems something was wrong. Now I have reinstall an "old" Ubuntu 11.04 64 bits from scratch and the compile process is fairly better but I obtain this failure : apps/hello_world/main.o: In function `console_rx_cb': apps/hello_world/main.c:59: undefined reference to `msgb_free' comm/libcomm.a(sercomm.o): In function `sercomm_alloc_msgb': ../../shared/libosmocore/include/osmocom/core/msgb.h:330: undefined reference to `msgb_alloc' comm/libcomm.a(sercomm.o): In function `sercomm_drv_rx_char': comm/sercomm.c:246: undefined reference to `msgb_free' comm/libcomm.a(sercomm.o): In function `dispatch_rx_msg': comm/sercomm.c:227: undefined reference to `msgb_free' comm/libcomm.a(sercomm.o): In function `sercomm_drv_pull': comm/sercomm.c:161: undefined reference to `msgb_dequeue' comm/sercomm.c:188: undefined reference to `msgb_free' comm/libcomm.a(sercomm.o): In function `sercomm_sendmsg': comm/sercomm.c:125: undefined reference to `msgb_enqueue' comm/libcomm.a(sercomm_cons.o): In function `msgb_alloc_headroom': ../../shared/libosmocore/include/osmocom/core/msgb.h:330: undefined reference to `msgb_alloc' make[1]: *** [board/compal_e88/hello_world.compalram.elf] error 1 make[1]: Leaving directory `/srv/osmocom-bb/src/target/firmware' make: *** [firmware] error 2 Any idea Regards

Put it somewhere and post a link, or preferable go through it yourself once more. Are you sure that autoconf/automake deal well with the encoding of your accents in the directories? thanks

I think you have simply created a broken build environment on your system. I have no idea how you did that, but you seem to just have a mess of toolchains. You need to clean that up and set up the neccessary system and target toolchains. Nothing more, nothing less. //Peter
