jamie@89: # SYNOPSIS
jamie@89: #
jamie@89: #   AC_PROG_JAVAC
jamie@89: #
jamie@89: # DESCRIPTION
jamie@89: #
jamie@89: #   AC_PROG_JAVAC tests an existing Java compiler. It uses the
jamie@89: #   environment variable JAVAC then tests in sequence various common
jamie@89: #   Java compilers. For political reasons, it starts with the free
jamie@89: #   ones.
jamie@89: #
jamie@89: #   If you want to force a specific compiler:
jamie@89: #
jamie@89: #   - at the configure.in level, set JAVAC=yourcompiler before calling
jamie@89: #   AC_PROG_JAVAC
jamie@89: #
jamie@89: #   - at the configure level, setenv JAVAC
jamie@89: #
jamie@89: #   You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
jamie@89: #
jamie@89: #   *Warning*: its success or failure can depend on a proper setting of
jamie@89: #   the CLASSPATH env. variable.
jamie@89: #
jamie@89: #   TODO: allow to exclude compilers (rationale: most Java programs
jamie@89: #   cannot compile with some compilers like guavac).
jamie@89: #
jamie@89: #   Note: This is part of the set of autoconf M4 macros for Java
jamie@89: #   programs. It is VERY IMPORTANT that you download the whole set,
jamie@89: #   some macros depend on other. Unfortunately, the autoconf archive
jamie@89: #   does not support the concept of set of macros, so I had to break it
jamie@89: #   for submission. The general documentation, as well as the sample
jamie@89: #   configure.in, is included in the AC_PROG_JAVA macro.
