Hello,

the detection of java is obviously existing, but in your case it is not
working if, as in your case, java is _not_ present.

On my system I have openjdk version 7 installed. It is detected, but I get

/usr/bin/mkdir -p java/org/octave
( cd ./java; javac -source 1.3 -cp org/octave -target 1.3 -d 
/home/haawda/paketierung/maintained_by_me/octave-hg/src/octave-build/scripts/java
 org/octave/ClassHelper.java )

I tried to add "-cp org/octave" to scripts/Makefile.in, with no change.

Is Octave supposed to work together with openjdk7?


Best Regards
