| # 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.
