Here is a summary of the main macros:
AC_PROG_JAVAC: finds a Java compiler.
AC_PROG_JAVA: finds a Java virtual machine.
AC_CHECK_CLASS: finds if we have the given class (beware of
AC_CHECK_RQRD_CLASS: finds if we have the given class and stops
AC_TRY_COMPILE_JAVA: attempt to compile user given source.
AC_TRY_RUN_JAVA: attempt to compile and run user given source.
AC_JAVA_OPTIONS: adds Java configure options.
AC_PROG_JAVA tests an existing Java virtual machine. It uses the
environment variable JAVA then tests in sequence various common
Java virtual machines. For political reasons, it starts with the
free ones. You *must* call [AC_PROG_JAVAC] before.
If you want to force a specific VM:
(but after AC_INIT)
You can use the JAVA variable in your Makefile.in, with @JAVA@.
*Warning*: its success or failure can depend on a proper setting of
the CLASSPATH env. variable.
TODO: allow to exclude virtual machines (rationale: most Java
programs cannot run with some VM like kaffe).
Note: This is part of the set of autoconf M4 macros for Java
programs. It is VERY IMPORTANT that you download the whole set,
some macros depend on other. Unfortunately, the autoconf archive
does not support the concept of set of macros, so I had to break it
