cannot execute OpenBSC programs
by AHMET GÜLTEKİN 23 Mar '10

23 Mar '10

Hi, I have downloaded and compiled both libosmocore and OpenBSC. However, when I try to execute an OpenBSC program (for example ipaccess-find) I see the following error ~/openbsc/openbsc/src# ./ipaccess-find eth0 ./ipaccess-find: error while loading shared libraries: libosmocore.so.0: cannot open shared object file: No such file or directory could you help me. Thanks. Ahmet

IMPORTANT: Building OpenBSC with libosmocore

Hi All Just to clarify this (since we've had another question on the ML) On Wed, Mar 03, 2010 at 10:15:44AM +0100, Holger Freyther wrote: > You are using the latest version of libosmocore but not the one of OpenBSC. You always need to use latest OpenBSC with latest libosmocore. We really cannot afford to spend more time in supporting any kind of forward/backward compatibility on a commit level. However, what we should do, is to make official releases of both the library and the OpenBSC program. OpenBSC will then require a particular version of libosmocore, and the configure script will notice if it is not available. I think OpenBSC has been quite useful and stable for quite some time, it would be great to make something like an 1.0 release at some point soon. Maybe zecke and myself can do this in the next couple of weeks. > libosmocore is a rather new library and we move stuff from OpenBSC into this > library, which means if you have a new version of libosmocore and a bit older > one of OpenBSC your compiler will see stuff twice. This will probably still be the case for the weeks to come, while even more stuff (e.g. 04.08 call control IE parsing / generation) moves into libosmocore. So please, always do a full cycle of * "git pull" on libosmocore * "git pull" on openbsc * "./configure && make install" on libosmocore * "./configure && make" on openbsc This way you'll get a consistent build.

BS-11 multidrop problem
by till 20 Mar '10

20 Mar '10

Hi, i want to operate two BS-11 via one E1-card. And i did it almost like here: http://lists.gnumonks.org/pipermail/openbsc/2009-August/000733.html But i dont know how to configure the bport1 object for multidrop and how to use the hfcmulti module to get two interfaces (for lcr i compiled misdn_l1loop but i think this isnt the right here ;)). So atm i am not able to communicate with the second BS11 :/. Any idea? Thx & Greets Till

i thought it is the same (sorry, but i could not yet compile it myself). try changing gsm.h line 79 into: extern char gsm_conf_error[128]; or extern char gsm_conf_error[]; anyway: i hate global return values and i will change it. ________________________________ Von: Ihab el Bakri [mailto:ihab.elbakri@hotmail.com] Gesendet: Dienstag, 16.

oops, try this: --- diff --git a/gsm_conf.c b/gsm_conf.c index 560d9b3..6daf9b3 100644 --- a/gsm_conf.c +++ b/gsm_conf.c @@ -12,7 +12,7 @@ #include "main.h" -char *gsm_conf_error = (char *)""; +char gsm_conf_error[128] = ""; /* read options * --- i never had an error in the config, so an error message never created.

GSM overview
by Andreas.Eversberg 15 Mar '10

15 Mar '10

hi, i just found some valuable information this weekend at www.informatik.hu-berlin.de/~goeller/isdn/ an introduction into gsm tracing in german http://www.informatik.hu-berlin.de/~goeller/isdn/DieGSMDmKanaele.pdf and the same in english http://www.informatik.hu-berlin.de/~goeller/isdn/GSMDmChannels.pdf it gives a rough history of GSM development, GSM network structure, framing, encryption, coding, and services - in just 100 pages. for me it is usefull to verify my parsing of SYSTEM INFORMATION messages. it describes traces of the most importaint messages. andreas
