Clojure Master on android

[MHOOO]

After reading on the dev group about running clojure on android I
figured I might just as well try the hello-dalvik example myself.
However the master branch fails because it is exhausing the heap?:

Anyone else experience this error?

Try giving the dx command a bit more memory by adding something like:

-Jmx1024m

before --dex.

For reference: I am not experiencing this problem on ubuntu lucid using
openjdk.

HTH,

Unfortunately that didn't work quite so well. The java process ended
up using 1.4GB ram without terminating (waited approximately 10
minutes before I killed it).

Anything wrong with my configuration?

[Remco van 't Veer]

Hmm, I have a 32 bit setup to that's probably the issue:

java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)

OpenJDK Server VM (build 14.0-b16, mixed mode)

Don't have a clue how to fix this.

[MHOOO]

Worked around the issue by removing some unnecessary stuff from the
clojure build.xml, thus making the final clojure.jar smaller. (In
particular the dx program would halt on generating code for zip
$remove).
