Environment

Environment:
OS: macOS High Sierra 10.13
Node: 8.6.0
Yarn: 1.1.0
npm: 5.3.0
Watchman: 4.9.0
Xcode: Xcode 9.0 Build version 9A235
Android Studio: 2.3 AI-162.4069837

Packages: (wanted => installed)
react: 16.0.0-alpha.12 => 16.0.0-alpha.12
react-native: ^0.48.2 => 0.48.3

Target Platform: iOS (10.3)

Steps to Reproduce

1. Place your the source of your react-native based project on a case sensitive file system on macOS (HFS+ or APFS).
2. Manage your dependencies using cocoapods instead of react-native link.

Here is a minimal Podfile:

platform :ios, '10.3'
inhibit_all_warnings!

target 'MyiOSProject' do
  # React dependencies
  pod 'Yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
  pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
  pod 'GLog', :podspec => '../node_modules/react-native/third-party-podspecs/GLog.podspec'
  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
  
  # React and its submodules
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge',
    'DevSupport',
    'RCTPushNotification',
    'RCTText',
    'RCTImage',
    'RCTAnimation',
    'RCTNetwork'
  ]
end

3. pod install

4. Try to build the resulting xcworkspace using Xcode.

Expected Behavior

When opening the xcworkspace and press build it should build without errors.

Actual Behavior

I get a build error saying .../Pods/Folly/folly/Range.h:33:10: 'glog/logging.h' file not found

How to fix

Just fix your supplied GLog.podspec to have spec.name = 'glog' instead of spec.name = 'GLog'. The name of the library is glog not GLog. Because of this misspelling cocoapods names the subdirectory in the Headers folder wrongly and therefore the inclusion error on case sensitive systems.
