My suspicion is that EXPORTEDCLASSES isn't defined, and so no stubs files
were created by the javah step. For the demo, both the demo.InputFile and
demo.OutputFile classes need to be listed in that macro. They are in the
Makefile we distribute, but double-check by doing a "make -n libstubs.c".
You should get something very similar to:
--------
javac demo/File.java
javac demo/InputFile.java
javac demo/OutputFile.java
for i in demo.InputFile demo.OutputFile ; \
do \
javah -classpath .:/home/tball/java/build/classes -d CClassHeaders/ $i ;\
done
javah -classpath .:/home/tball/java/build/classes -d stubs/ \
-stubs demo.InputFile demo.OutputFile
cat /home/tball/java/build/include/StubPreamble.h stubs/*.stubs > libstubs.c
