OSX 10.14 builds incompatible for 10.13

[jdekonin]

Using the latest shas, when I build on 10.14 using clang 9.1, the resulting binary does not work on 10.13. A binary built on the 10.13 system does work on the 10.14 system.

The error I get is

bash-3.2$ ./jdk/bin/java -version
dyld: Symbol not found: ___objc_personality_v0
  Referenced from: /private/tmp/./jdk/bin/java
  Expected in: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices

Makes sense. Similar problems occur on Linux as well. i.e. you can't build on Ubuntu 16 and run the resulting JVM on CentOS 6.

OpenJ9 built on OSX 10.14 should work till OSX 10.9 because the build scripts set MACOSX_DEPLOYMENT_TARGET (env. variable) to 10.9. Below are the specific details for the above issue.

72 errors similar to the above two sample errors are seen when building OpenJ9 JDK11 on OSX with XCode 9: linker_errors_osx_1014.log. The issue is related to the functioning of the linker on OSX 10.14 + Xcode 9.

Other projects have experienced similar issues; example: https://github.com/golang/go/issues/27095. In this project, some people were able to resolve the issue: update OS or upgrade XCode version or don't use homebrew to install dependencies. Someone will have to verify if these solutions can be used with OpenJ9.

I also noticed other setup differences between OSX 10.13 and 10.14:

• 10.13 was using bash version 4.4.23, and 10.14 was using bash version 5.0.3.
• 10.13 had darwin17.7.0, and 10.14 had darwin18.2.0; guess: darwin corresponds to the OSX version.
• Due to different darwin versions, the functionality of clang may also differ.
• pkg-config was unavailable on 10.13 but available on 10.14.
