What is the Build Process for Codes inside jdk/src/macosx/native/jobjc (original) (raw)

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.

Hi David,

Under src/macosx/native/jobjc folder, it contains not only native *.m source files, but also *.java files. If you check the build results in build/macosx-x8664-normal-server-release/jdk folder, it contains some build results specific for jobjc, say gensrcjobjc/, gensrcheadersjobjc/, jobjcclasses/, jobjcclassesheaders/. So it must have some extra build steps to generate those jobjc results. And I wonder what they are and why they are special and not merged into the regular native compilation and java compilation processes. Thanks! -Dan

I don't quite understand the question but all native code building is handled via jdk/makefiles/CompileNativeLibraries.gmk which in turn utilizes the set up from /common/makefiles/NativeCompilation.gmk HTH David On 18/04/2013 9:51 AM, Dan Xu wrote: Adding core-libs-dev

As for the sourcecodes for mac platform, it has a special place holding native and java codes for jdk, jdk/src/macosx/native/jobjc. I wonder how those codes are builtand whether its compilation process has any special handling. Thanks! -Dan
