@thomasvl - PTAL

@muxi - The protobuf team will also have to agree to maintain/updating this like they do the objc one with releases.

[muxi]

Sounds good. We will ask them about it. Thanks!

[thomasvl]

@muxi this seems fine to me, so you'll need to get someone on the protobuf team for final sign off on name (i.e. - Protobuf-cc or something else) and also that why want to maintain/publish this with releases.

@thomasvl - we will get this done. Thank you for the help again Thomas.

Thanks for catching that. Fixed.

Hi there,
I'm posting this here for others that try to use it.
I tried using it with:

  pod 'Protobuf-C++', :git => 'https://github.com/protocolbuffers/protobuf.git', :tag => 'v3.11.2'

and the Protobuf-C++ target doesn't compile.
Looks like a header path issue (I have a bunch of those):

...../Pods/Protobuf-C++/src/google/protobuf/any.cc:31:10: fatal error: 'google/protobuf/any.h' file not found
#include <google/protobuf/any.h>
         ^~~~~~~~~~~~~~~~~~~~~~~
1 warning and 1 error generated.

After digging around looks like this pod does not support the use_frameworks! configuration.
After switching this off it looks like it's working :)

I have 2 questions for you:

1. Are you planning to publish this package to cocoapods anytime soon?
2. Are you planning to support useframeworks! option?

Regarding question 2, I managed to compile it by manually adding this search path to Protobuf-C++ pod target.

${PODS_TARGET_SRCROOT}/src

You can do it in the podspec file like so:

  spec.pod_target_xcconfig = {
    'HEADER_SEARCH_PATHS' => '"${PODS_TARGET_SRCROOT}/src"'
  }

But it crashes on startup with the following error:

dyld: Library not loaded: @rpath/Protobuf_C_.framework/Protobuf_C_

  Reason: image not found

You can clone this repo to reproduce the issue:

git clone https://github.com/shali3/ios-single-view-app.git

I have the same issue, please fix it!

This is a workaround you can do on your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if target.name == 'Protobuf-C++'
        # Pure C++ doesn't support framework imports. We need to help it find it's path.
        target.build_configurations.each do |config|
          config.build_settings['HEADER_SEARCH_PATHS'] = "${PODS_TARGET_SRCROOT}/src";
        end
      end
    end
  end
end
