|
|---|
| 3 | dnl Here is a summary of the main macros:
|
|---|
| 4 | dnl
|
|---|
| 5 | dnl AC_PROG_JAVAC: finds a Java compiler.
|
|---|
| 6 | dnl
|
|---|
| 7 | dnl AC_PROG_JAVA: finds a Java virtual machine.
|
|---|
| 8 | dnl
|
|---|
| 9 | dnl AC_CHECK_CLASS: finds if we have the given class (beware of
|
|---|
| 10 | dnl CLASSPATH!).
|
|---|
| 11 | dnl
|
|---|
| 12 | dnl AC_CHECK_RQRD_CLASS: finds if we have the given class and stops
|
|---|
| 13 | dnl otherwise.
|
|---|
| 14 | dnl
|
|---|
| 15 | dnl AC_TRY_COMPILE_JAVA: attempt to compile user given source.
|
|---|
| 16 | dnl
|
|---|
| 17 | dnl AC_TRY_RUN_JAVA: attempt to compile and run user given source.
|
|---|
| 18 | dnl
|
|---|
| 19 | dnl AC_JAVA_OPTIONS: adds Java configure options.
|
|---|
| 20 | dnl
|
|---|
| 21 | dnl AC_PROG_JAVA tests an existing Java virtual machine. It uses the
|
|---|
| 22 | dnl environment variable JAVA then tests in sequence various common
|
|---|
| 23 | dnl Java virtual machines. For political reasons, it starts with the
|
|---|
| 24 | dnl free ones. You *must* call [AC_PROG_JAVAC] before.
|
|---|
| 25 | dnl
|
|---|
| 26 | dnl If you want to force a specific VM:
|
|---|
| 27 | dnl
|
|---|
| 28 | dnl - at the configure.in level, set JAVA=yourvm before calling
|
|---|
| 29 | dnl AC_PROG_JAVA
|
|---|
| 30 | dnl
|
|---|
| 31 | dnl (but after AC_INIT)
|
|---|
| 32 | dnl
|
|---|
| 33 | dnl - at the configure level, setenv JAVA
|
|---|
| 34 | dnl
|
|---|
| 35 | dnl You can use the JAVA variable in your Makefile.in, with @JAVA@.
|
|---|
| 36 | dnl
|
|---|
| 37 | dnl *Warning*: its success or failure can depend on a proper setting of
|
|---|
| 38 | dnl the CLASSPATH env. variable.
|
|---|
| 39 | dnl
|
|---|
| 40 | dnl TODO: allow to exclude virtual machines (rationale: most Java
|
|---|
| 41 | dnl programs cannot run with some VM like kaffe).
|
|---|
| 42 | dnl
|
|---|
| 43 | dnl Note: This is part of the set of autoconf M4 macros for Java
|
|---|
| 44 | dnl programs. It is VERY IMPORTANT that you download the whole set,
|
|---|
| 45 | dnl some macros depend on other. Unfortunately, the autoconf archive
|
|---|
| 46 | dnl does not support the concept of set of macros, so I had to break it
|
|---|
| 47 | dnl for submission.
