React-native: [0.62.0-rc.3] Catalyst macOS build issue typedef redefinition with different types

React Native version:

System:

    Xcode: 11.3.1/11C504 - /usr/bin/xcodebuild
  npmPackages:
    react: 16.11.0 => 16.11.0 
    react-native: 0.62.0-rc.1 => 0.62.0-rc.1

Steps To Reproduce

1. Create a new project npx react-native init SandboxProject_62 --version 0.62.0-rc.1
2. Enable macOS target in xcode
3. Build

Describe what you expected to happen:

Successful build for macOS target

Errors

[...]/SandboxProject_62/ios/Pods/Headers/Private/Flipper-Folly/folly/portability/Time.h:51:17:
Typedef redefinition with different types ('uint8_t' (aka 'unsigned char') vs 'enum clockid_t')

If I comment out this line, Flipper-Folly build does seem to pass but I end up with an OpenSSL linking error:

ld: in [...]/SandboxProject_62/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a(cryptlib.o), building for Mac Catalyst, but linking in object file built for iOS Simulator, file '[...]/SandboxProject_62/ios/Pods/OpenSSL-Universal/ios/lib/libcrypto.a' for architecture x86_64

Would be really awesome to have a working macOS target for the 0.62 release as everything seems to be pretty ready.

FYI this bug still exists in the latest 0.62.0-rc.2 release

I've opened an issue in Flipper: https://github.com/facebook/flipper/issues/834

Hi @mgcrea,

Have you had any success since posting this? I'm having the same problem and got stuck at libcrypto.a error.

@0xmtn @mgcrea I fixed this with updating my iOS Deployment Target Build setting in my app to be 9.0 and my platform :ios '10.0' to be platform :ios '9.0' in my ios/Podfile :

Change this:

ios/Podfile

platform :ios '10.0'

to this:

ios/Podfile

platform :ios, '9.0'

Don't forget to npx pod-install from the root of your project afterwards.

I guess this means flipper-folly doesn't like iOS version 10 as a deployment target...
