9 # DESCRIPTION
10 #
11 # AX_TRY_RUN_JAVA attempt to compile and run user given source.
12 #
13 # *Warning*: its success or failure can depend on a proper setting of the
14 # CLASSPATH env. variable.
15 #
16 # Note: This is part of the set of autoconf M4 macros for Java programs.
17 # It is VERY IMPORTANT that you download the whole set, some macros depend
18 # on other. Unfortunately, the autoconf archive does not support the
19 # concept of set of macros, so I had to break it for submission. The
20 # general documentation, as well as the sample configure.in, is included
21 # in the AX_PROG_JAVA macro.
