Re: Location of the JavaFX runtime library

The "--with-javafx" option doesn't seem to work:

Making all in gnu/kawa/javafx
java -classpath "../../..:./../../..:$CLASSPATH" kawa.repl -d ../../.. -P `echo gnu-kawa-javafx|sed -e s/-/./g`. --module-static-run  -C GroupObjectBuilder.scm MakeScene.scm defs.scm
(compiling GroupObjectBuilder.scm to gnu.kawa.javafx.GroupObjectBuilder)

MakeScene.scm:7:28: unknown type name 'javafx.scene.Parent'
make[1]: *** [scm-classes.stamp] Error 255
make: *** [all-recursive] Error 1

This is due to the fact that the jfxrt.jar is not present in the default classpath of the JDK (contrary to what the download page/documentation claims):

$ javap javafx.scene.Node
Error:  class not found: javafx.scene.Node

The "--with-javafx=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jre/lib/jfxrt.jar" option does work:

Making all in gnu/kawa/javafx
java -classpath "../../..:./../../..:/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jre/lib/jfxrt.jar:$CLASSPATH" kawa.repl -d ../../.. -P `echo gnu-kawa-javafx|sed -e s/-/./g`. --module-static-run  -C GroupObjectBuilder.scm MakeScene.scm defs.scm
(compiling GroupObjectBuilder.scm to gnu.kawa.javafx.GroupObjectBuilder)
(compiling MakeScene.scm to gnu.kawa.javafx.MakeScene)
(compiling defs.scm to gnu.kawa.javafx.defs)
echo timestamp > scm-classes.stamp
echo timestamp > ../../../kawa-jar.stamp

My environment here is a stock Mac OS X Lion with Oracle JDK 7u4:
