What is the Build Process for Codes inside jdk/src/macosx/native/jobjc

[Erik Joelsson]

Hello Dan,

These sources are indeed treated separately. I don't actually know why, 
but they were in the old build. (There the native was compiled as an 
XCode project and the java code with Ant). When converting to the new 
build, we strived to keep differences in build output to a minimum. This 
means that the library libJObjC is built as both 32 and 64 bit and 
packaged as a universal binary. The java source for this is compiled 
with source/target 1.5 for the same reason. Now that equality with the 
old build is no longer a requirement, I would welcome the removal of 
this and moving the source to more standard locations.

To see how it's done, look in jdk/makefiles/CompileNativeLibraries.gmk 
and CompileJavaClasses.gmk and search for jobjc.
