13 # AX_PROG_JAR tests for an existing jar program. It uses the environment
14 # variable JAR then tests in sequence various common jar programs.
16 # If you want to force a specific compiler:
18 # - at the configure.in level, set JAR=yourcompiler before calling
21 # - at the configure level, setenv JAR
23 # You can use the JAR variable in your Makefile.in, with @JAR@.
25 # Note: This macro depends on the autoconf M4 macros for Java programs. It
26 # is VERY IMPORTANT that you download that whole set, some macros depend
27 # on other. Unfortunately, the autoconf archive does not support the
28 # concept of set of macros, so I had to break it for submission.
30 # The general documentation of those macros, as well as the sample
31 # configure.in, is included in the AX_PROG_JAVA macro.
