How to fix headers name conflict between 2 pods?

[dawidzawada]

Hi, I'm working on React Native Turbo Modules library and I'm facing the issue - C++ Pod I'm installing - 'zxing-cpp' in my library podspec have a header file called Point.h - unfortunately this name is not very unique and it conflicts with header file Point.h from React-graphics development Pod.

I can clearly see that zxing-cpp looks for Points.h inside of React-graphics. Is there a way to fix this issue without changing the pods source code? I've heard that i can adjust header mapping config, is there a way to adjust it in for example podspec file to make zxing-cpp look for headers inside it own source code?

This is the file of zxing that imports wrong header:

Basically this can be reproduced by creating a turbomodules library with create-react-native-library and adding zxing to dependencies like that:

require "json"

package = JSON.parse(File.read(File.join(__dir__, "package.json")))
folly_compiler_flags = '-DFOLLY_NO_CONFIG -DFOLLY_MOBILE=1 -DFOLLY_USE_LIBCPP=1 -Wno-comma -Wno-shorten-64-to-32'

Pod::Spec.new do |s|
  s.name         = "react-native-lemon"
  s.version      = package["version"]
  s.summary      = package["description"]
  s.homepage     = package["homepage"]
  s.license      = package["license"]
  s.authors      = package["author"]

  s.platforms    = { :ios => min_ios_version_supported }
  s.source       = { :git => "https://github.com/dawidzawada/react-native-lemon.git", :tag => "#{s.version}" }

  s.source_files = "ios/**/*.{h,m,mm}", "cpp/**/*.{hpp,cpp,c,h}"
  s.dependency "zxing-cpp/Core"

  # Use install_modules_dependencies helper to install the dependencies if React Native version >=0.71.0.
  # See https://github.com/facebook/react-native/blob/febf6b7f33fdb4904669f99d795eba4c0f95d7bf/scripts/cocoapods/new_architecture.rb#L79.
  if respond_to?(:install_modules_dependencies, true)
    install_modules_dependencies(s)
  else
    s.dependency "React-Core"

    # Don't install the dependencies when we run `pod install` in the old architecture.
    if ENV['RCT_NEW_ARCH_ENABLED'] == '1' then
      s.compiler_flags = folly_compiler_flags + " -DRCT_NEW_ARCH_ENABLED=1"
      s.pod_target_xcconfig    = {
          "HEADER_SEARCH_PATHS" => "\"$(PODS_ROOT)/boost\"",
          "OTHER_CPLUSPLUSFLAGS" => "-DFOLLY_NO_CONFIG -DFOLLY_MOBILE=1 -DFOLLY_USE_LIBCPP=1",
          "CLANG_CXX_LANGUAGE_STANDARD" => "c++17"
      }
      s.dependency "React-Codegen"
      s.dependency "RCT-Folly"
      s.dependency "RCTRequired"
      s.dependency "RCTTypeSafety"
      s.dependency "ReactCommon/turbomodule/core"
      s.dependency "ReactCommon/turbomodule/core"
    end
  end
end
