hi, I try to work with ztdummy in order to make conference. But I never succeed to install it. When I compile zaptel I have unresolved symbol in the end and when I lauch modprobe ztdummy I have this : /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol proc_mkdir_Rsmp_220b03b4 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol create_proc_entry_Rsmp_3a9bfbd2 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_output_wakeup_Rsmp_fc4c9ef0 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __write_lock_failed /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol request_module_Rsmp_27e4dc04 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol register_chrdev_Rsmp_65405f1d /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol remove_proc_entry_Rsmp_cfd23da1 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __tasklet_schedule_Rsmp_ed5c73bf /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol tasklet_kill_Rsmp_79ad224b /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_input_error_Rsmp_14a5ddc7 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __generic_copy_to_user_Rsmp_d523fdd3 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_unregister_channel_Rsmp_d0b1c903 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol unregister_chrdev_Rsmp_c192d491 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol remove_wait_queue_Rsmp_2d22232f /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol alloc_skb_Rsmp_3702adc3 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __read_lock_failed /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __wake_up_Rsmp_127fda83 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol skb_over_panic_Rsmp_7acbf56a /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_register_channel_Rsmp_bd63214e /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol printk_Rsmp_1b7d4074 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol kfree_Rsmp_037a0cba /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol tasklet_init_Rsmp_a5808bbf /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __kfree_skb_Rsmp_980007b5 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol cpu_raise_softirq_Rsmp_d01f3ee8 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_unit_number_Rsmp_960fd73e /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol sprintf_Rsmp_3c2c5af5 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_channel_index_Rsmp_dc85af48 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol kmalloc_Rsmp_93d4cfe6 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol ppp_input_Rsmp_65b5d6aa /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __pollwait_Rsmp_57ac46fa /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol schedule_Rsmp_4292364c /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol __generic_copy_from_user_Rsmp_116166aa /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol softnet_data_Rsmp_20eece54 /lib/modules/2.4.7-10/misc/zaptel.o: unresolved symbol add_wait_queue_Rsmp_0987e9bc /lib/modules/2.4.7-10/misc/zaptel.o: insmod /lib/modules/2.4.7-10/misc/zaptel.o failed /lib/modules/2.4.7-10/misc/zaptel.o: insmod ztdummy failed I try to recompile my kernel but i always have these messages.
