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. +# +# A Web page, with a link to the latest CVS snapshot is at +# <http://www.internatif.org/bortzmeyer/autoconf-Java/>. +# +# This is a sample configure.in Process this file with autoconf to +# produce a configure script. +# +# AC_INIT(UnTag.java) +# +# dnl Checks for programs. +# AC_CHECK_CLASSPATH +# AC_PROG_JAVAC +# AC_PROG_JAVA +# +# dnl Checks for classes +# AC_CHECK_RQRD_CLASS(org.xml.sax.Parser) +# AC_CHECK_RQRD_CLASS(com.jclark.xml.sax.Driver) +# +# AC_OUTPUT(Makefile) +# +# LAST MODIFICATION +# +# 2000-07-19 +# +# COPYLEFT +# +# Copyright (c) 2000 Stephane Bortzmeyer <bortzmeyer@pasteur.fr> +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of the +# License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
