# SYNOPSIS
|
|
#
|
|
# AC_CHECK_CLASS
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# AC_CHECK_CLASS tests the existence of a given Java class, either in
|
|
# a jar or in a '.class' file.
|
|
#
|
|
# *Warning*: its success or failure can depend on a proper setting of
|
|
# the CLASSPATH env. variable.
|
|
#
|
|
# 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.
