I’m trying to build this SIP application using PJSIP.

When I compile I get this error and no idea why or how something is duplicated.
I checked the:
Build Phases -> Link Binary With Libraries
Build Phases -> Compile Sources

for duplicates but there isn’t any.

Here is the error:

ignoring file /Users/kaanersan/Gogo/Gogo/libsrtp-arm-apple-darwin9.a, file was built for archive which is not the architecture being linked (i386): /Users/kaanersan/Gogo/Gogo/libsrtp-arm-apple-darwin9.a

ld: 126 duplicate symbols for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I had to cut out some parts of the error since it didn’t fit into the question but I believe the most important part is the last part anyways and that’s the red error, the rest are warnings.

Some help would be greatly appreciated!

Edit:

    It’s probably due to some funky include or erroneous definition statement about kSIPCallState, kSIPRegState or kSIPMwiInfo, but it doesn’t seem to be in ASIDataDecompressor. It’s necessarily from ASIHTTPRequest or something it includes.

    Reading the error message shows that only three symbols are duplicated (kSIPCallState, kSIPRegState or kSIPMwiInfo) and they always involve ASIDataDecompressor. Looking from there where there could be duplicate symbols is your best shot at debugging linker errors.
