Cannot compile, even after install of dependencies

[csotiriou]

I have downloaded the libechoprint project. After installing Homebrew, and boost and other dependencies, I was able to produce libechoprint-codegen-ios.a successfully, and make a FAT file out of it to use in the echo print for iOS sample.

However, I can't compile the echo print-ios sample. It gives me this error:

Undefined symbols for architecture armv7:
"__ZN7CodegenC1EPKfji", referenced from:
__Z15codegen_wrapperPKfi in Codegen_wrapper.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any help? I really need this framework.

Hi soulstormgr,

Thanks for the report. I will look into this and let you know as soon as I have some more information for you.

Best,

Integrated with my iOS project but most of time it shows song not found message. how can I solve this issue?
Please help me.

I guess this is because xcode doesn't compile the library for both i386 and armv7. I used the script in the project for compiling the codegen library from this tutorial and it worked for me.

I'm also unable to compile the echoprint-ios-sample app using Xcode 5. The latest approach I have tried is in this stackoverflow post: http://stackoverflow.com/questions/12135898/echoprint-ios-missing-framework

This is the error I get when building:

I was able to workaround my issue in Xcode 5 by changing the "deployment target" build setting from iOS 7 to iOS 6.
