# ===========================================================================
#
# SYNOPSIS
#
# AX_JNI_INCLUDE_DIR
#
# DESCRIPTION
#
# AX_JNI_INCLUDE_DIR finds include directories needed for compiling
# programs using the JNI interface.
#
# JNI include directories are usually in the Java distribution. This is
# deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
# that order. When this macro completes, a list of directories is left in
# the variable JNI_INCLUDE_DIRS.
#
# Example usage follows:
#
# AX_JNI_INCLUDE_DIR
#
# for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
# do
# CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
# done
#
# If you want to force a specific compiler:
#
# - at the configure.in level, set JAVAC=yourcompiler before calling
# AX_JNI_INCLUDE_DIR
#
# - at the configure level, setenv JAVAC
#
# This macro depends on AC_CANONICAL_HOST which requires that config.guess
# and config.sub be distributed along with the source code. See autoconf
# manual for details.
#
# Note: This macro can work with the autoconf M4 macros for Java programs.
# This particular macro is not part of the original set of macros.
