I have moved the ZRTP/SRTP files in the third_party structure
thus no more files in the pjmedia core distribution. The structure
is:
$PJBASE/third_party/build/zsrtp - Makefile to build the stuff
$PJBASE/third_party/zsrtp - include, src, ... files
These directories can be provided as a separate download/tar file.
The zsrtp Makefile builds the library and copies it to third_party/lib
as usual.
To simplify usage of transport_zrtp for an application the zsrtp
Makefile creates a build.mak file in $PJBASE/third_party/build/zsrtp
that an application Makefile can include.
For example:
#Modify this to point to the PJSIP location.
PJBASE=/home/werner/devhome/pjproject-1.8.5
include $(PJBASE)/build.mak
include $(PJBASE)/third_party/build/zsrtp/build.mak
CC = $(PJ_CC)
LDFLAGS = $(PJ_LDFLAGS)
LDLIBS = $(PJ_LDLIBS)
CFLAGS = $(PJ_CFLAGS)
CPPFLAGS= ${CFLAGS}
# If your application is in a file named myapp.cpp or myapp.c
# this is the line you will need to build the binary.
all: pjapp.c
pjapp: pjapp.c
$(CC) -o $@ $< \
$(CPPFLAGS) \
$(LDFLAGS) \
$(LDLIBS)
clean:
rm -f pjapp.o pjapp
the zsrtp/build.mak extends some $(PJ_*) variables to include the zsrtp
include path and the library.
Regis, would this fit into your Android build structure?
Only topic to solve: enable an application to tell pjsua to use the
transport_zrtp :-) .
