Compilation problem on xcode4.2 for pjsip

Question

While I run my project on xcode 4.2, I got this answer with 31 errors of the missing .o file

, and this error looks something like this:

I also got a 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 someone help me solve this problem?

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 launch, you are least building armv7 . This is the most important architecture, because Apple only accepts assemblies with at least this architecture (if I'm not mistaken).

Unfortunately, the libraries you link to do not contain code for this architecture. (That's why you get warnings at the top). The following error messages confirm that they are actually caused by the pjsip and pjmedia libraries.

I don’t know whether libraries were loaded somewhere or built from source code. But you will need libraries that are at least built for armv7 . It would be even better to have libraries built for all architectures.

It is best to follow this section on the Getting Started page, which shows how to create for multiple architectures.
