|

|
---|
| 9 | # DESCRIPTION
|
---|
| 10 | #
|
---|
| 11 | # AX_JNI_INCLUDE_DIR finds include directories needed for compiling
|
---|
| 12 | # programs using the JNI interface.
|
---|
| 13 | #
|
---|
| 14 | # JNI include directories are usually in the Java distribution. This is
|
---|
| 15 | # deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
|
---|
| 16 | # that order. When this macro completes, a list of directories is left in
|
---|
| 17 | # the variable JNI_INCLUDE_DIRS.
|
---|
| 18 | #
|
---|
| 19 | # Example usage follows:
|
---|
| 20 | #
|
---|
| 21 | # AX_JNI_INCLUDE_DIR
|
---|
| 22 | #
|
---|
| 23 | # for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
|
---|
| 24 | # do
|
---|
| 25 | # CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
|
---|
| 26 | # done
|
---|
| 27 | #
|
---|
| 28 | # If you want to force a specific compiler:
|
---|
| 29 | #
|
---|
| 30 | # - at the configure.in level, set JAVAC=yourcompiler before calling
|
---|
| 31 | # AX_JNI_INCLUDE_DIR
|
---|
| 32 | #
|
---|
| 33 | # - at the configure level, setenv JAVAC
|
---|
| 34 | #
|
---|
| 35 | # Note: This macro can work with the autoconf M4 macros for Java programs.
|
---|
| 36 | # This particular macro is not part of the original set of macros.
