It uses the +# environment variable JAVAC then tests in sequence various common +# Java compilers. For political reasons, it starts with the free +# ones. +# +# If you want to force a specific compiler: +# +# - at the configure.in level, set JAVAC=yourcompiler before calling +# AC_PROG_JAVAC +# +# - at the configure level, setenv JAVAC +# +# You can use the JAVAC variable in your Makefile.in, with @JAVAC@. +# +# *Warning*: its success or failure can depend on a proper setting of +# the CLASSPATH env. variable. +# +# TODO: allow to exclude compilers (rationale: most Java programs +# cannot compile with some compilers like guavac). +# +# 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. The general documentation, as well as the sample +# configure.in, is included in the AC_PROG_JAVA macro. +# +# 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.
