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.

|

dnl
|

dnl Finds the appropriate java compiler on your path. By preference the
|
||||
dnl java compiler is gcj, then jikes then javac.
|
||||
dnl
|
||||
dnl The macro can take one argument specifying a space separated list
|
||||
dnl of java compiler names.
|
||||
dnl
|
||||
dnl For example:
|
||||
dnl
|
||||
dnl AC_PROG_JAVA_CC(javac, gcj)
|
||||
dnl
|
||||
dnl The macro also sets the compiler options variable: JAVA_CC_OPTS to
|
||||
dnl something sensible:
|
||||
dnl
|
||||
dnl - for GCJ it sets it to: @GCJ_OPTS@
|
||||
dnl (if GCJ_OPTS is not yet defined then it is set to "-C")
|
||||
dnl
|
||||
dnl - no other compiler has applicable options yet
|
||||
dnl
|

dnl Here's an example configure.in:

dnl

dnl AC_INIT(Makefile.in)

dnl AC_PROG_JAVA_CC()

dnl AC_OUTPUT(Makefile)

dnl PROJECT_ROOT := @srcdir@
