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.

please try the following patch. i cannot test it right now. especially the gsm.cpp change is relevant. i hope that everything is clean now. diff --git a/bchannel.c b/bchannel.c index f49572b..baa8434 100644 --- a/bchannel.c +++ b/bchannel.c @@ -23,7 +23,7 @@ #include <netinet/in.h> #include <netdb.h> #include <sys/socket.h> -#include <mISDNif.h> +#include <mISDN/mISDNif.h> #include <mISDN/mISDNcompat.h> int __af_isdn = MISDN_AF_ISDN; diff --git a/gsm.cpp b/gsm.cpp index b2bdd6b..d8906c4 100644 --- a/gsm.cpp +++ b/gsm.cpp @@ -44,12 +44,9 @@ static struct timer_list db_sync_timer; #include "gsm_audio.h" -#undef AF_ISDN -#undef PF_ISDN -extern int AF_ISDN; -#define PF_ISDN AF_ISDN } +#include <mISDN/mISDNcompat.h> struct lcr_gsm *gsm = NULL; > symbol lookup error: /sbin/lcr: undefined symbol: AF_ISDN

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

>. /lcr: symbol lookup error: ./lcr: undefined symbol: init_af_isdn pull lcr again. the mISDNuser header paths have changed. i changed more stuff. also try to remove the /usr/include/mISDNuser directory. it is obsolete. now compat_af_isdn.h can be removed from openbsc also. todo so, replace the include of this file by: #include <mISDN/mISDNcompat.h> int __af_isdn = MISDN_AF_ISDN; maybe it is better to use "static int", so it will not conflict when linking to lcr... we will see. the function call init_af_isdn(); can be removed.

hi, now after changing code of lcr, it compiles with libosmocom and openbsc. all packets are the latest (mISDN, mISDNuser, libosmocom, openbsc, lcr) i have started it without crashing, but i could not test it. please change to "develop" branch of LCR. be sure to add links to openbsc and libosmocore to the LCR source directories: libosmocore -> ../libosmocore/ openbsc -> ../openbsc/openbsc/ also i found some little problems while compiling osmocore and openbsc: the 'extern' is missing: diff --git a/include/osmocore/gsm48.h b/include/osmocore/gsm48.h index 6356379..787cdd0 100644 --- a/include/osmocore/gsm48.h +++ b/include/osmocore/gsm48.h @@ -6,7 +6,7 @@ extern const struct tlv_definition gsm48_att_tlvdef; extern const char *cc_state_names[32]; -const char *gsm48_cc_msg_names[0x40]; +extern const char *gsm48_cc_msg_names[0x40]; const char *rr_cause_name(uint8_t cause); void gsm48_generate_lai(struct gsm48_loc_area_id *lai48, uint16_t mcc, an here is a warning i did not analyse yet: /usr/lib/gcc/i686-pc-linux-gnu/4.3.4/../../../../i686-pc-linux-gnu/bin/l d: Warning: size of symbol `rsl_rlm_cause_strs' changed from 8 in ./openbsc/src/libbsc.a(abis_rsl.o) to 120 in /usr/local/lib/libosmocore.so regards, andreas
