Re: configure options so can run output binaries on armv5tel iPAQ 3955) arch?

Hi,

2 things:

1) .class files are architecture-independent.  So you can always
compile your java program (provided that they don't use native
libraries) elsewhere and copy the .class/.jar to your iPAQ.

2) as Chris mentionned, try to get the jikes compiler.

jikes + SableVM Classpath libraries gives you a full compilation system.
(as jikes by itself does not include class libraries).

SableVM has a javac wrapper around jikes.  However, it has been added
after the 1.1.10 release.

You can write your own wrapper or patch 1.1.10 with:
http://www.sable.mcgill.ca/~dbelan2/ebuilds/dev-java/sablevm/files/javac-wrapper-patch.diff
and rebuild it.  Note that the SableVM javac wrapper is first file in
the patch, could just use it and remove the + before the lines.

If you decide to patch and rebuild, you will need to run:
aclocal && \
libtoolize --force && \
autoconf && \
autoheader && \
automake --foreign -a -c

that requires having the autoconf/automake/libtool installed.
