# =========================================================================== # http://www.gnu.org/software/autoconf-archive/ax_prog_javac.html # =========================================================================== # # SYNOPSIS # # AX_PROG_JAVAC # # DESCRIPTION # # AX_PROG_JAVAC tests an existing Java compiler. 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.
