Build Open JDK 7 on Mac OSX (TOTD #172)
- by arungupta
The complete requirements, pre-requisites, and steps to build
OpenJDK 7 port on Mac OSX are described
here. The steps are very clearly explained and here are the
exact ones I followed on my MacBook Pro 10.7.2:
Confirm the version of pre-installed Java as:
> java -versionjava version "1.6.0_26"Java(TM) SE Runtime Environment (build 1.6.0_26-b03-383-11A511c)Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-383, mixed mode)
Download and install Mercurial from mercurial.berkwood.com
(zip bundle for 10.7 is here).
It gets installed in the /usr/local/bin directory.
Get the source code as (commands highlighted in bold):
hg clone
http://hg.openjdk.java.net/macosx-port/macosx-port
destination directory: macosx-port

Install Xcode
from the App Store. Include /Developer/usr/bin in
PATH.
Note: JDK 1.6.0_26 ame pre-installed on my laptop and I
installed Xode after that. The compilation went fine and there
was no need to re-install the Java for Mac OS X as mentioned in
the original steps.
Build the code as:
make ALLOW_DOWNLOADS=true SA_APPLE_BOOT_JAVA=true
ALWAYS_PASS_TEST_GAMMA=true ALT_BOOTDIR=`/usr/libexec/java_home -v
1.6` HOTSPOT_BUILD_JOBS=`sysctl -n hw.ncpu`
The final output is shown as:

Change the directory and verify the version:
>cd
build/macosx-universal/j2sdk-image/1.7.0.jdk/Contents/Home/bin
>./java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build
1.7.0-internal-arungup_2011_11_19_00_32-b00)
OpenJDK 64-Bit Server VM (build 21.0-b17, mixed mode)
Now go fix
some bugs, file
new bugs, or discuss at the
macosx-port-dev mailing list.
