Building J2ObjC

Requirements

• Apple Mac OS X system
• Latest version of Xcode
• Apache Maven

Note: Maven is no longer distributed with Xcode's command-line tools. Here is a well-written installation guide by Pankaj Kumar.

Building J2ObjC

To build from a command-line in a Terminal window, run:

$ make dist

to build the full distribution,

$ make test

to run all unit tests, and

$ make clean

to remove all files generated by the build.

Parallel Builds

The J2ObjC build supports parallel builds, which are specified using the -j<n> flag, where n is the maximum number of concurrent tasks. The maximum depends on how fast/powerful your system is; we suggest starting with -j4. Increase the number to shorten build times if your system can handle it, and decrease it if make fails with system errors.
