Hi, I built pjproject-1.2 package and tried different sample applications like pjsua and simple_ua; they all worked as expected Now I was trying to code any pjsip-based application by myself, first checking that the Makefile was properly set. Then I followed the guidelines from here<http://trac.pjsip.org/repos/wiki/Getting_Started_Using>, so I wrote a Makefile like this: PJBASE=/home/dulceangustia/pjproject-1.2/ include $(PJBASE)/build.mak CC = $(APP_CC) LDFLAGS = $(APP_LDFLAGS) LDLIBS = $(APP_LDLIBS) CFLAGS = $(APP_CFLAGS) CPPFLAGS= ${CFLAGS} all: voip-app.c voip-app: voip-app.c $(CC) -o $@ $< $(CPPFLAGS) $(LDFLAGS) $(LDLIBS) clean: rm -f voip-app.o voip-app Being my voip-app.c file: #include <pjlib.h> #include <pjlib-util.h> #include <pjmedia.h> #include <pjmedia-codec.h> #include <pjsip.h> #include <pjsip_simple.h> #include <pjsip_ua.h> #include <pjsua-lib/pjsua.h> int main() { puts("Hello pj"); return 0; } Makefile is properly formatted, but when issuing the make command I get that there's nothing to do with 'all'. It seems that the options APP_CC, APP_LDLIBS and so on are not properly set. I built pjsip with no options, so I don't know how to solve it or if I must specify every option. I just used this Makefile template as I'm using pjproject 1.2 package. Note that this is my first Makefile U_U. Any help on this will be much appreciated. Sorry for the inconvenience.
