dnl @synopsis AC_PROG_JAVA
|
||
|
|
dnl
|
||
|
|
dnl Here is a summary of the main macros:
|
||
|
|
dnl
|
||
|
|
dnl AC_PROG_JAVAC: finds a Java compiler.
|
||
|
|
dnl
|
||
|
|
dnl AC_PROG_JAVA: finds a Java virtual machine.
|
||
|
|
dnl
|
||
|
|
dnl AC_CHECK_CLASS: finds if we have the given class (beware of
|
||
|
|
dnl CLASSPATH!).
|
||
|
|
dnl
|
||
|
|
dnl AC_CHECK_RQRD_CLASS: finds if we have the given class and stops
|
||
|
|
dnl otherwise.
|
||
|
|
dnl
|
||
|
|
dnl AC_TRY_COMPILE_JAVA: attempt to compile user given source.
|
||
|
|
dnl
|
||
|
|
dnl AC_TRY_RUN_JAVA: attempt to compile and run user given source.
|
||
|
|
dnl
|
||
|
|
dnl AC_JAVA_OPTIONS: adds Java configure options.
|
||
|
|
dnl
|
||
|
|
dnl AC_PROG_JAVA tests an existing Java virtual machine. It uses the
|
||
|
|
dnl environment variable JAVA then tests in sequence various common
|
||
|
|
dnl Java virtual machines. For political reasons, it starts with the
|
||
|
|
dnl free ones. You *must* call [AC_PROG_JAVAC] before.
|
||
|
|
dnl
|
||
|
|
dnl If you want to force a specific VM:
|
||
|
|
dnl
|
||
|
|
dnl - at the configure.in level, set JAVA=yourvm before calling
|
||
|
|
dnl AC_PROG_JAVA
|
||
|
|
dnl
|
||
|
|
dnl (but after AC_INIT)
|
||
|
|
dnl
|
||
|
|
dnl - at the configure level, setenv JAVA
|
||
|
|
dnl
|
||
|
|
dnl You can use the JAVA variable in your Makefile.in, with @JAVA@.
|
||
|
|
dnl
|
||
|
|
dnl *Warning*: its success or failure can depend on a proper setting of
|
||
|
|
dnl the CLASSPATH env. variable.
|
||
|
|
dnl
|
||
|
|
dnl TODO: allow to exclude virtual machines (rationale: most Java
|
||
|
|
dnl programs cannot run with some VM like kaffe).
|
||
|
|
dnl
|
||
|
|
dnl Note: This is part of the set of autoconf M4 macros for Java
|
||
|
|
dnl programs. It is VERY IMPORTANT that you download the whole set,
|
||
|
|
dnl some macros depend on other. Unfortunately, the autoconf archive
|
||
|
|
dnl does not support the concept of set of macros, so I had to break it
|
||
|
|
dnl for submission.
