I get this error ../io-layer/.libs/libwapi.a(events.o): In function `_wapi_handle_set_signal_state': ../../mono/io-layer/handles-private.h:157: undefined reference to `mono_mutex_unlock_in_cleanup' ../io-layer/.libs/libwapi.a(handles.o): In function `_wapi_handle_new': /root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/handles.c:337: undefined reference to `mono_mutex_unlock_in_cleanup' ../io-layer/.libs/libwapi.a(handles.o): In function `_wapi_handle_new_from_offset': /root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/handles.c:426: undefined reference to `mono_mutex_unlock_in_cleanup' /root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/handles.c:480: undefined reference to `mono_mutex_unlock_in_cleanup' ../io-layer/.libs/libwapi.a(handles.o): In function `_wapi_handle_foreach': /root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/handles.c:620: undefined reference to `mono_mutex_unlock_in_cleanup' ../io-layer/.libs/libwapi.a(handles.o):/root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/handles.c:662: more undefined references to `mono_mutex_unlock_in_cleanup' follow ../io-layer/.libs/libwapi.a(threads.o): In function `thread_start_routine': /root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/threads.c:181: undefined reference to `GC_pthread_detach' ../io-layer/.libs/libwapi.a(threads.o): In function `CreateThread': /root/freeswitch.trunk/libs/mono-1.1.13.8/mono/io-layer/threads.c:309: undefined reference to `GC_pthread_create' collect2: ld returned 1 exit status make[4]: *** [pedump] Error 1 make[4]: Leaving directory `/root/freeswitch.trunk/libs/mono-1.1.13.8/mono/metadata' make[3]: *** [install-recursive] Error 1 make[3]: Leaving directory `/root/freeswitch.trunk/libs/mono-1.1.13.8/mono' make[2]: *** [install-recursive] Error 1 make[2]: Leaving directory `/root/freeswitch.trunk/libs/mono-1.1.13.8' ERROR make[1]: *** [depends] Error 1 make[1]: Leaving directory `/root/freeswitch.trunk/src/mod/languages/mod_mono' make: *** [modules] Error 1 Can some please help?
