Hi all, I've been playing with the new mono api on the development version of Kamailio. I'm having some problems with it, perhaps there's something someone here knows that would help. If there's a better place to post this question please guide me to the right direction. I'm using CentOS 6.2, installed mono with yum, the mono version is 2.4.3.1. I had problems compiling the app_mono module, I got errors like: Package mono-2 was not found in the pkg-config search path. Perhaps you should add the directory containing `mono-2.pc' to the PKG_CONFIG_PATH environment variable No package 'mono-2' found ... So I changed the makefile to the one below (replaced "mono-2" to "mono" from the default). Then got it compiled and app_mono.so was generated. I don't know much about makefiles but me guessing what to do with it got the thing compiled. # # include ../../Makefile.defs auto_gen= NAME=app_mono.so BUILDER = $(shell which pkg-config) ifeq ($(BUILDER),) DEFS+=-D_REENTRANT -I/usr/include/mono LIBS= -lmono -lm -lrt -ldl -lpthread else DEFS+= $(shell pkg-config --cflags mono) LIBS = $(shell pkg-config --libs mono) endif DEFS+=-DOPENSER_MOD_INTERFACE SERLIBPATH=../../lib SER_LIBS+=$(SERLIBPATH)/kcore/kcore include ../../Makefile.modules Then I compiled Kamailio with the app_mono module included, during compilation I got output like this: [root@monotest kamailio]# make all CC (gcc) [M app_mono.so] app_mono_api.o app_mono_api.c: In function âsr_mono_logâ: app_mono_api.c:318: warning: implicit declaration of function âmono_freeâ CC (gcc) [M app_mono.so] app_mono_mod.o make[2]: `libkcore.so.1.0' is up to date. LD (gcc) [M app_mono.so] app_mono.so ... I added my params on the config: loadmodule "app_mono.so" ... modparam("app_mono", "load", "/usr/local/etc/kamailio/mono/MonoTest1.exe") Everything compiled though and I did not notice any errors. However, there must be something wrong with either my environment, mono version, compiling something or something else, command kamailio -c gives output with errors (note the warning before and the error below about mono_free): [root@monotest kamailio]# kamailio -c loading modules under /usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/ 0(26471) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/local/lib/kamailio/modules/app_mono.so>: /usr/local/lib/kamailio/modules/app_mono.so: undefined symbol: mono_free 0(26471) : <core> [cfg.y:3565]: parse error in config file /usr/local/etc/kamailio/modules.cfg, line 90, column 12-24: failed to load module 0(26471) ERROR: <core> [modparam.c:162]: set_mod_param_regex: No module matching <app_mono> found 0(26471) : <core> [cfg.y:3568]: parse error in config file /usr/local/etc/kamailio/modules.cfg, line 281, column 74: Can't set module parameter 0(26471) ERROR: <core> [cfg.y:3429]: cfg. parser: failed to find command mono_run Any ideas on what's the problem? I'll try the same on Ubuntu to compare but any suggestions and advice would be appreciated! cheers, Pirjo Ahvenainen
