Building Android FS with non standard java installation

[nictam]

Hi,

I am trying to build Android FS (eclair AOSP) on a Ubuntu server where
I don't have sudo permissions. So I downloaded JDK 1.5 from Sun and
installed it on my file system (e.g. ~/java).

I am setting the following env var before building (based on this
discussion http://ubuntuforums.org/showthread.php?t=253530)

export JDK_HOME=~/java/jdk1.5.0_22
export PATH=$JDK_HOME/bin/:$JDK_HOME/jre/bin:$PATH
export MANPATH=${MANPATH}:$JDK_HOME/man/
export JAVA_HOME=$JDK_HOME

I have all kind of errors like these:

build/tools/droiddoc/src/DroidDoc.java:1000: cannot find
symbol
symbol : class
ClassDoc
location: class
DroidDoc
ClassDoc classDoc = (ClassDoc)

errors

After settings the env var, I have the following Java install:

$ java -version
java version "1.5.0_22"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_22-b03)
Java HotSpot(TM) Server VM (build 1.5.0_22-b03, mixed mode)


If I don't set the env variables, I have this:

$ java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) Server VM (build 14.0-b16, mixed mode)

Is there a way I can configure my server (without root privileges) so
that I can build Android with Java installed in a non standard
location?

thanks

Your best bet is to wait until we work our way through the changes
that will allow to build with a Java 1.6 host environment.

Hi JBQ,

I am also getting the same errors as Nictam is getting on my ubuntu
9.04.
my java version is 1.5_15 only not 1.6.

Problem arises with erro code 41. and showing cannot found javadoc.

Thanks,
Asif

Are you sure that you have a real Java and not one of the
alternatives? I seem to remember that some of the non-Sun
implementations don't have enough javadoc support to build Android.

well, in fact it's now working fine... but I can hardly believe why...
if I add $JDK_HOME/jre/bin/ in my PATH, my build is failing, and if I
put $JDK_HOME/jre/bin (e.g. without the trailing '/') the build is
working fine. I have not taken the time to dig further.

so I confirm that I could build Eclair public code base with a non
standard installation of JAVA in my HOME folder (since I cannot make
'sudo' commands on my company's servers). [I also mentioned that here:
http://groups.google.com/group/android-platform/browse_thread/thread/558e83421b7c3333]

can you please confirm if the method looks good to you? I think there
should be many people out there that would be happy to have official
(I mean from google) instructions on how to build without messing up
the system config (e.g. installing new java).

It looks like you've been making quite some discoveries.

It'd be great if you could put together some kind of "start to finish"
instructions and post them on this group (possibly in a new thread) so
that other people can validate them.

done. I have submitted a new topic 'Building Platform code with a non
standard JAVA installation', it's pending moderators approval for now.

let's follow up on this new thread.

thx
