Creating private cocoapods with static libs

I tried to build a new private cocoapods library which embeds a static library (provided by an external vendor). The static library is composed by two kind of files : XX-libs-simulator.a and XX-libs.a.

When I run 

"pod spec lint . --verbose --use-libraries"

I get

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

** BUILD FAILED **

The following build commands failed:

Analyzed 1 podspec.

When I compile it with my Xcode, I have no issues. I already tried to change the following values :

  • "VALID ARCHITECTURES" : armv7, arm64 and x86_64, i386

  • "BUILD ONLY ACTIVE ARCHITECTURES" : both (yes / no)

For your information, the lipo output for the external libs is : 

lipo -info libXX.a
libXX.a are: armv7 arm64 

lipo -info libXX-simulator.a
libXX-simulator.a are i386 x86_64

How to get pod to compile my library like XCode ?

Solution

  • I didn't have the answer to my question but to avoid this issue I chose to create my own library without cocoapods. I think when you need a particular configuration, it's probably the easiest and the best way to do it manually using the old school methods.
