# SYNOPSIS
|
|
#
|
|
# AC_PROG_JAVA
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# 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
|
|
# CLASSPATH!).
|
|
#
|
|
# AC_CHECK_RQRD_CLASS: finds if we have the given class and stops
|
|
# otherwise.
|
|
#
|
|
# 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:
|
|
#
|
|
# - at the configure.in level, set JAVA=yourvm before calling
|
|
# AC_PROG_JAVA
|
|
#
|
|
# (but after AC_INIT)
|
|
#
|
|
# - at the configure level, setenv JAVA
|
|
#
|
|
# 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
|
|
# for submission.
