Using --with-java and kaffe 1.0.6, as provided on disc 2 with RedHat 7.0, here are the last few lines of my failed compile:

=======================================================

The compilation bug is easily rectified by editing ext/java/Makefile and removing the line that reads:

@test ! -f reflect.class || mv reflect.class net/php # bug in KJC javac

Apparently, this was a work around for a bug in kaffe, but the bug in kaffe (at least in RedHat 7.0's dist) seems to be gone, and the workaround, in fact, BREAKS the compilation. A version check for kaffe may be needed to determine whether the workaround needs to be applied or not.

Hope this helps. I love PHP (but also Perl and Python, to be honest - I pretty much a big fan of any language beginning with a "P" :D).

Ok, got an update for ya:

javac is still not working correctly. I don't have the time to explore whether it is a problem with kaffe itself or RedHat has introduced a bug in their dist, but here it is:

The *old* javac "bug" (which ext/java/Makefile was attempting to work around) seems like it was probably that it would ignore the directory path given in the argument (at least if it found a file of the same name in the CWD). Well, now it seems to put in the CWD *twice* in the output file. Specifically, "javac net/php/reflect.java" created "net/php/net/php/reflect.class". (Perhaps RH had a patch to fix the original problem, and then kaffe fixed it, but RH's patch is still applied to, thereby fixing the bug *twice* - I'm just guessing). It seems to me that the simplest reliable way now is to get rid of the path issue completely by making javac always work in the CWD. I.e. remove these two lines from ext/java/Makefile:

javac net/php/reflect.java
@test ! -f reflect.class || mv reflect.class net/php # bug in KJC javac

and replace them simply with:

(cd net/php; javac reflect.java)

I think this will work no matter what buggy or non-buggy javac is being used.

Is this still happening with latest snapshot from http://snaps.php.net/ ??
