Use bitcode for libprotobuf-lite.a and cardboard-xr-plugin/tree/master/Runtime/iOS/cardboard_api.a

[HerotechDevs]

I am getting an error in XCode

"CardboardXrProvider.a does not contain bitcode"

Even if I disable bitcode in the project settings it keeps giving this error. what to do?
(If i disable bitcode for unity framework I get a lot of other errors)

This issue should be solved on v1.2.0 (to be released very soon) as we have merged both the SDK and XR Provider into one single library (.a). Furthermore, release v1.2.0 also will include the XR Provider source code, which makes it possible for you to rebuild the binaries from source as needed to enable bitcode. Bear in mind that you will need to rebuild the protobuf library as well (see: https://developers.google.com/cardboard/develop/ios/protobuf).

With 1.2.0 out, you can now compile the library yourself.

Any news about 1.2.0?

Hi!

Following from issue #184, under iOS we would need cardboard_api.a to be able to compile with ENABLE_BITCODE enabled out-of-the-box. This is the normal configuration expected by Apple for release on the App Store.

To support this, the pre-compiled libprotobuf-lite.a for iOS should be provided with ENABLE_BITCODE enabled.

While it's not a problem for cardboard_api.a (as it's be compiled from this project), re-compiling libprotobuf-lite.a is more involved as it requires to install other external tools. As support for iOS is part of the core library, I think it would be better to provide the proper setup right out-of-the-box.

From this bug report, it's not clear (to me) if you plan to provide this pre-compiled library with ENABLE_BITCODE enabled or if this is leaved to us to re-compile it. (well.. as the bug is still open, maybe you plan to fix it... but I would like to be sure what the plan is :) )

Thanks.

Sorry for the long delay here, @kafumanto. The right solution for this would be avoiding the need to use a protobuf prebuilt binary and instead adding Protobuf C++ as a dependency in the Xcode project. This would allow the user to enable or not bitcode according to their needs.

A fix for this has been submitted and it will be included in v1.9.0. Thanks for reaching out!
