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 +# AX_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 AX_PROG_JAVA macro. +# +# LICENSE +# +# Copyright (c) 2008 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.
