I have an compile error as follow, when I used klaus's class PjCallback.
main.cpp:(.text+0x8a): undefined reference to `globalPjCallback'main.cpp:(.text+0xa4): undefined reference to `PjCallback::PjCallback()'main.cpp:(.text+0xbf): undefined reference to `PjCallback::on_incoming_call_wrapper(int, int, pjsip_rx_data*)'main.cpp:(.text+0xc9): undefined reference to `PjCallback::on_call_media_state_wrapper(int)'main.cpp:(.text+0xd3): undefined reference to `PjCallback::on_call_state_wrapper(int, pjsip_event*)'collect2: ld returned 1 exit statusmake: *** [main.o] Error 1
Actually, I have defined all this function in Pjcallback class, and call them as follow:
/* Init pjsua */ { pjsua_config cfg; pjsua_logging_config log_cfg; PjCallback *pjCallback;
globalPjCallback = pjCallback = 0; pjCallback = new PjCallback();
pjsua_config_default(&cfg); cfg.cb.on_incoming_call = PjCallback::on_incoming_call_wrapper; //&on_incoming_call; cfg.cb.on_call_media_state =PjCallback::on_call_media_state_wrapper; // &on_call_media_state; cfg.cb.on_call_state = PjCallback::on_call_state_wrapper; //&on_call_state;
Can you help me?
my make file as follow:
#Modify this to point to the PJSIP location.PJBASE=/home/ym/legacy_project_here/pjproject-0.9.0
include $(PJBASE)/build.mak
CC = $(APP_CC)CC = g++LDFLAGS = $(APP_LDFLAGS)LDLIBS = $(APP_LDLIBS)CFLAGS = $(APP_CFLAGS)CPPFLAGS= ${CFLAGS}
# this is the line you will need to build the binary.all: PjSourcePort.o PjSinkPort.o PjCallback.o main.o
PjSourcePort.o: PjSourcePort.cppPjSinkPort.o: PjSinkPort.cppPjCallback.o: PjCallback.cppmain.o: main.cpp
$(CC) -o $@ $< $(CPPFLAGS) $(LDFLAGS) $(LDLIBS)
clean: rm -f PjSourcePort.o PjSinkPort.o PjCallback.o main.o sipgw
Thanks very much
