7 | # SYNOPSIS | |
8 | # | |
9 | # AX_PROG_JAVA | |
10 | # | |
11 | # DESCRIPTION | |
12 | # | |
13 | # Here is a summary of the main macros: | |
14 | # | |
15 | # AX_PROG_JAVAC: finds a Java compiler. | |
16 | # | |
17 | # AX_PROG_JAVA: finds a Java virtual machine. | |
18 | # | |
19 | # AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!). | |
20 | # | |
21 | # AX_CHECK_RQRD_CLASS: finds if we have the given class and stops | |
22 | # otherwise. | |
23 | # | |
24 | # AX_TRY_COMPILE_JAVA: attempt to compile user given source. | |
25 | # | |
26 | # AX_TRY_RUN_JAVA: attempt to compile and run user given source. | |
27 | # | |
28 | # AX_JAVA_OPTIONS: adds Java configure options. | |
29 | # | |
30 | # AX_PROG_JAVA tests an existing Java virtual machine. It uses the | |
31 | # environment variable JAVA then tests in sequence various common Java | |
32 | # virtual machines. For political reasons, it starts with the free ones. | |
33 | # You *must* call [AX_PROG_JAVAC] before. | |
34 | # | |
35 | # If you want to force a specific VM: | |
36 | # | |
37 | # - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA | |
38 | # | |
39 | # (but after AC_INIT) | |
40 | # | |
41 | # - at the configure level, setenv JAVA | |
42 | # | |
43 | # You can use the JAVA variable in your Makefile.in, with @JAVA@. | |
44 | # | |
45 | # *Warning*: its success or failure can depend on a proper setting of the | |
46 | # CLASSPATH env. variable. | |
47 | # | |
48 | # TODO: allow to exclude virtual machines (rationale: most Java programs | |
49 | # cannot run with some VM like kaffe). | |
50 | # | |
51 | # Note: This is part of the set of autoconf M4 macros for Java programs. | |
52 | # It is VERY IMPORTANT that you download the whole set, some macros depend | |
53 | # on other. Unfortunately, the autoconf archive does not support the | |
54 | # concept of set of macros, so I had to break it for submission. | |

59 | # This is a sample configure.in Process this file with autoconf to produce | |
60 | # a configure script. | |
61 | # | |
62 | # AC_INIT(UnTag.java) | |
63 | # | |
64 | # dnl Checks for programs. | |
65 | # AC_CHECK_CLASSPATH | |
66 | # AX_PROG_JAVAC | |
67 | # AX_PROG_JAVA | |
68 | # | |
69 | # dnl Checks for classes | |
70 | # AX_CHECK_RQRD_CLASS(org.xml.sax.Parser) | |
71 | # AX_CHECK_RQRD_CLASS(com.jclark.xml.sax.Driver) | |
