mISDN/lcr/asterisk compilation issues

Dear openbsc folks, i am following up on the osmo-nitb/ggsn/sgsn config running w/ a nanoBTS-1800. i have been trying to get mISDN/lcr to build to be able to create the chan_lcr into asterisk (i am more familiar w/ dahdi/asterisk for isdn cahnnels) though so far i am not able to get it to work : *configuration : **host : running linux debian lenny 2.6.26-2-686) **autoconf 2.61 **mISDN-1_1_9.1 (downloaded as a tarball) builds mISDN_dsp.ko but not mISDN_l1loop.ko **lcr doest not build (./configure passes) /usr/src/lcr# git-apply --verbose lcrOpenBSC.patch Checking patch gsm_bs.cpp... error: while searching for: int bts_model_nanobts_init(void); static struct log_target *stderr_target; /* timer to store statistics */ #define DB_SYNC_INTERVAL 60, 0 static struct timer_list db_sync_timer; error: patch failed: gsm_bs.cpp:39 error: gsm_bs.cpp: patch does not apply /usr/src/lcr# make (...) gcc -DWITH_GSM_BS -I./openbsc/include -I./libosmocore/include -I./openbsc -Wall -DCONFIG_DATA="\"/usr/local/lcr\"" -DSHARE_DATA="\"/usr/local/lcr\"" -DLOG_DIR="\"/usr/local/lcr\"" -DEXTENSION_DATA="\"/usr/local/lcr/extensions\"" -D_GNU_SOURCE -fPIC -c bchannel.c -o bchannel.po bchannel.c:29:31: error: mISDN/mISDNcompat.h: No such file or directory bchannel.c:30: error: 'MISDN_AF_ISDN' undeclared here (not in a function) bchannel.c:31:24: error: mISDN/q931.h: No such file or directory bchannel.c: In function 'bchannel_create': bchannel.c:148: error: 'PF_ISDN' undeclared (first use in this function) bchannel.c:148: error: (Each undeclared identifier is reported only once bchannel.c:148: error: for each function it appears in.) bchannel.c:174: error: 'AF_ISDN' undeclared (first use in this function) make[1]: *** [bchannel.po] Error 1 make[1]: Leaving directory `/usr/src/lcr' (lcr from git : commit 6e1e99808e5b1c16b00904d31f95d0b74487023e) *questions : **do i need misdn to build lcr if running a nanobts w/ Abis-over-ip ? **am i missing something in the build order ? **any packaged version of misdn for debian 2.6.26-2-686 ? thanks for your support.
