Re: Kawa on Android - unable to use 'for-each' form

[Benny Tsai <benny dot tsai at gmail dot com>]

Using the files you provided, I have partial success!  "text:" still
doesn't compile, but I can now compile and run code containing the
"for-each" form.  The latter was a much more serious issue for me, so
I'm ecstatic!

After I calmed down a bit, I tried to determine the differences
between the 1.11.1 source you provided and the rev. 6931 source I got
from SVN.  The attached pre-ant-diff.txt is the diff of freshly
downloaded copies of the two sources.  post-ant-diff.txt is the diff
of the sources after I ran "ant -Denable-android=true" to generate the
kawa jar file, then "ant clean" to get rid of the generated files (to
avoid cluttering up the diff).

I ran diff via "diff -qrbx .* kawa-svn kawa-1.11.1" to ignore space
changes and .cvs*/.svn* files.

Comparing the two diffs, there are 5 java files that were
pre-processed by ant in the 1.11.1 version but not the SVN version.
This is also shown in the select-android section of ant-1.11.1.txt and
ant-svn.txt, the output captured while running ant on the respective
sources.  I've attached both versions of the 5 changed java files in
1.11.1-files.tar and svn-files.tar.  I don't know why pre-processing
behaved differently in the two runs, but I'm guessing this may be why
"for-each" works in the 1.11.1 source but not the rev. 6931 source I
got from SVN?

While looking at the select-android output, I also noticed that in
both runs, select-android displayed the following flags: +JAVA5 +JAVA2
-JAVA6 -JAVA6COMPAT5 -JAVA7.  I'm not familiar with the workings of
ant, but since I'm running JDK 1.6.0_24-b07, does this mean the
pre-processing done by select-android was done using the wrong
settings?
