Static library not built with bitcode

[muellermichel]

I'd like to add the static libary to a project, but it is not compatible anymore because of lacking bitcode. I also didn't find an xCode project to build the static library with that flag enabled. Is there an easy way to solve this?

Hello Michel.

Yes, it is possible to do so, but you first need to tell me which platform you target. Is is watchOS, iOS, OS X, tvOS?

[muellermichel]

Hi. It's iOS. I temporarily solved it by just adding the sources to the project instead, that works for me too. But thanks for your quick reaction!

OK, so that's cool for now. Yet your request is perfectly legit: let's keep this issue open until it is resolved.

Same problem here. Can you please rebuild the static library with bitcode enabled, so that the LLVM Optimization from Apple works?

hello @MarcDahlem. Do you know how to do this? A PR would be welcome.

hi @groue thanks for your quick answer.

I don't know your exact build process, but I think you're using xcodebuild in your makefile.

Therefore, here is an StackOverflow Answer, which explains in detail how to do it:

Maybe there is also another way, by directly changing the xcodeproj. See:

http://stackoverflow.com/questions/32868297/compiling-ios-library-with-bitcode-enabled

How to test if it works:

• create a new iOS Project
• Include GRMustache and call it somwhere (include as static library)
• Execute: It should work
  • (At the moment there is an error message, that says that if the project itself has bitcode enabled, all referenced libraries must have it as well)

Great, @MarcDahlem, you have all the pieces of the puzzle. I think you can apply it to the Makefile that produces the static library.
