I'm using echoprint API for song search from last 3 months. But suddenly it started giving me below errors. Already I have face many problems while adding that API to my project & now it start giving me linker error. It was working for me previously. Error like this:
"Codegen::Codegen(float const*, unsigned int, int)", referenced from: _GetPCMFromFile in File.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
ld: symbol(s) not found for architecture i386
ld: warning: directory not found for option '-L-L/Users/prajaktakulkarni/Downloads/echoprint-codegen-4.12 2/src/echoprint-codegen-ios/build/Release-iphoneos' ld: warning: ignoring file /Users/prajaktakulkarni/Documents/Instajam/libechoprint-codegen-ios.a, missing required architecture i386 in file /Users/prajaktakulkarni/Documents/Instajam/libechoprint-codegen-ios.a (2 slices) Undefined symbols for architecture i386: "Codegen::Codegen(float const*, unsigned int, int)", referenced from: _GetPCMFromFile in File.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)
The error message is saying that the static library libechoprint-codegen-ios.a hasn't been built for the i386 architecture - which is the architecture used by the simulator.
You can find out which architectures the static library has been built for by running the following code in Terminal:
lipo -info ~/Documents/Instajam/libechoprint-codegen-ios.a
It will likely tell you it is built for armv7 and armv7s. That will support all but the oldest iOS devices at the time of writing.
You could build libechoprint-codegen-ios.a to run on a simulator. Here's a good stackoverflow post if you are interested in doing that: Build fat static library (device + simulator) using Xcode and SDK 4+
The easiest option would be to just plug your phone in and not worry about building a fat static library. :D
