5 | # SYNOPSIS | |
6 | # | |
7 | # AX_JNI_INCLUDE_DIR | |
8 | # | |
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 | # This macro depends on AC_CANONICAL_HOST which requires that config.guess |
36 | # and config.sub be distributed along with the source code. See autoconf | |
37 | # manual for details. | |
38 | # | |

39 | # Note: This macro can work with the autoconf M4 macros for Java programs. |
40 | # This particular macro is not part of the original set of macros. | |
