# SYNOPSIS
|
|
#
|
|
# AC_PROG_JAVAC
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# AC_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
|
|
# 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.
