I have modified a source file in open-jdk-6 and now want to rebuild it. In all guides it is stated that the build process is done via make. However I don't see any Makefile or target.
$ pwd
/usr/lib/jvm/java-6-openjdk-amd64
$ ls
ASSEMBLY_EXCEPTION com docs java jre lib org src.zip sunw
bin demo include javax launcher man sample sun THIRD_PARTY_README
I am using Ubuntu-AMD64
UPDATE
I have installed the sources according to dpkg command
$ dpkg -l | grep jdk

What did you modify? You only have a binary distribution, not the source tree. – Daniel B – 2014-04-02T18:10:04.777
I modified a sun/misc/somethings.java. please see the updated post – mahmood – 2014-04-02T18:13:33.430
The source code isn't something you install with
– Daniel B – 2014-04-02T19:41:28.663apt-get. It's available on the project's homepage, here.
