You've got the headers of pjsip, but it seems the compiler can't find the implementation (.c files).

Thanks for reply,

Can you please please tell me what I have to do for that?

I have already changed Header search paths and Library Search Path to desired locations.
then also I am getting this linker error..

the real error is that the compiler cannot find the symbol(s)

that means: you either need the source code for the function AND it to be in scope of the place objc is calling it

OR

you need the library file with the extern symbol declared already

Thanks for your reply,

Yes I have library files ".a files" for this and I am also providing "Library Search Path" in Project settings for them. But then also I am getting this error.

Please suggest me some solution..

your in heaps of luck:

i had to learn this the hard way, what architecture is the library? if it is ARM you need to change your build settings to "iPhone" instead of simulator
