jamie@89: # SYNOPSIS
jamie@89: #
jamie@89: #   AC_JNI_INCLUDE_DIR
jamie@89: #
jamie@89: # DESCRIPTION
jamie@89: #
jamie@89: #   AC_JNI_INCLUDE_DIR finds include directories needed for compiling
jamie@89: #   programs using the JNI interface.
jamie@89: #
jamie@89: #   JNI include directories are usually in the java distribution This
jamie@89: #   is deduced from the value of JAVAC. When this macro completes, a
jamie@89: #   list of directories is left in the variable JNI_INCLUDE_DIRS.
jamie@89: #
jamie@89: #   Example usage follows:
jamie@89: #
jamie@89: #       AC_JNI_INCLUDE_DIR
jamie@89: #
jamie@89: #       for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
jamie@89: #       do
jamie@89: #               CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
jamie@89: #       done
jamie@89: #
jamie@89: #   If you want to force a specific compiler:
jamie@89: #
jamie@89: #   - at the configure.in level, set JAVAC=yourcompiler before calling
jamie@89: #   AC_JNI_INCLUDE_DIR
jamie@89: #
jamie@89: #   - at the configure level, setenv JAVAC
jamie@89: #
jamie@89: #   Note: This macro can work with the autoconf M4 macros for Java
jamie@89: #   programs. This particular macro is not part of the original set of
jamie@89: #   macros.
