[Live-devel] problem in compiling simpleRtspClient

[Davood Falahati]

Dear Community,

I am interested in live streaming with your precious library. I am on
MacOsx Elcaptain and I made project with the following command:

./genMakeFiles macosx
./make
./make install

everything went well and I have installed libraries in /usr/local/lib and
headers in /usr/loca/include/liveMedia . etc.

I am using xCode 7. I created a C++ project and copied testRtspClient, in
my main file.

I have added all the headers and libraries in my project settings, now I
receive the below error. I could not find a proper help covering what to do
on Internet. Would you please help me?
