LinuxQuestions.org - Problems with Sofia-Sip

hello!

I hope, this is the right thread, otherwise I want to apologise! I'm a total newbie to the topic "sofia-sip" and my experiences in Linux are also not that good, so I wanted to start with a "hello-world" from http://gitorious.org/sofia-sip/pages/SofiaTutorial. I use Ubuntu on a Virtual Box, have run the installation with

./configure
make
make install

and have set the following symbolic links

ln -s /usr/local/lib/pkgconfig/sofia-sip-ua.pc /usr/lib/pkgconfig/sofia-sip-ua.pc
ln -s /usr/local/lib/pkgconfig/sofia-sip-ua-glib.pc /usr/lib/pkgconfig/sofia-sip-ua-glib.pc
sudo ln -s libsofia-sip-ua.so /usr/lib/libsofia-sip-ua.so (although I think it's not necessary)

Now my problem is the following: when I run the makefile, these error occur:

user@shafner:~/Sofia_SIP/Wrapper/HelloSofiaSIP$ make
gcc `pkg-config sofia-sip-ua --cflags --libs` -DCALLER -g -O0 -L/usr/lib/libsu.a -L/usr/lib/libsofia-sip-ua.so -L/usr/lib/libsofia-sip-ua.so.0 -L/usr/lib/libsofia-sip-ua.so.0.6.0 -L/usr/lib/pkgconfig/sofia-sip-ua.pc -L/usr/lib/pkgconfig/sofia-sip-ua-glib.pc -L/usr/lib -lsofia-sip-ua \

make: *** [hello-caller] Error 1

The functions, which are displayed above, belong to the su part of sofia-sip. The including of su.h (so that I can see that at least the errors with su_init and su_deinit are solved) in hello.c didn't change anything. I also tried to modify the makefile, now it's a bit of a mess, because I added some linkings successively:

CFLAGS = -g -O0

all: hello-caller hello-callee

hello-caller: hello.c
gcc `pkg-config sofia-sip-ua --cflags --libs` -DCALLER $(CFLAGS) -L/usr/lib/libsu.a -L/usr/lib/libsofia-sip-ua.so -L/usr/lib/pkgconfig/sofia-sip-ua.pc -L/usr/lib/pkgconfig/sofia-sip-ua-glib.pc -L/usr/lib -lsofia-sip-ua \
-o hello-caller hello.c

hello-callee: hello.c
gcc `pkg-config sofia-sip-ua --cflags --libs` $(CFLAGS) -L/usr/lib/libsu.a -L/usr/lib/pkgconfig/sofia-sip-ua.pc -L/usr/lib/libsofia-sip-ua.so -L/usr/lib/pkgconfig/sofia-sip-ua-glib.pc -L/usr/lib -lsofia-sip-ua \
-o hello-callee hello.c

clean:
rm hello-caller hello-callee

Does anyone of you please could help me or have experience with sofia sip?
