Trouble of compilation on xcode4.2 for pjsip

Question

While I run my project on xcode 4.2 I got this kind of response with 31 errors of .o file missing

and that 31 error looks like this

Also I got linker error like

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Can anyone help me to solve this ?

Answer 1

A typical iPhone project compiles for three different architectures: armv6 and armv7 (two different generations of the iPhone processor) and i386 (for the simulator). In the current build run, you are a least building for armv7. It's the most important architecture as Apple only accepts builds with at least this architecture (if I'm not mistaken).

Unfortunately, the libraries you're linking with do not contain code for this architecture. (That's why you're getting the warnings at the top). The following error messages confirm that it's indeed caused by the pjsip and pjmedia libraries.

I don't know whether you downloaded the libraries somewhere or built them from the source code. But you'll need libraries that are at least built for armv7. Even better would be to have libraries built for all architectures.

You best follow this section of the Getting Started page that shows how to build for multiple architectures.
