# 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
|
||||||
|
#
|
||||||
|
# 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.
