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 CLASSPATH!).
|
|
dnl
|
|
dnl AC_CHECK_RQRD_CLASS: finds if we have the given class and stops 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 Java
|
|
dnl virtual machines. For political reasons, it starts with the free ones.
|
|
dnl 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 AC_PROG_JAVA
|
|
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 the
|
|
dnl CLASSPATH env. variable.
|
|
dnl
|
|
dnl TODO: allow to exclude virtual machines (rationale: most Java programs
|
|
dnl cannot run with some VM like kaffe).
|
|
dnl
|
|
dnl Note: This is part of the set of autoconf M4 macros for Java programs.
|
|
dnl It is VERY IMPORTANT that you download the whole set, some
|
|
dnl macros depend on other. Unfortunately, the autoconf archive does not
|
|
dnl support the concept of set of macros, so I had to break it for
|
|
dnl submission.

|
|
dnl A Web page, with a link to the latest CVS snapshot is at
|
|
dnl <http://www.internatif.org/bortzmeyer/autoconf-Java/>.
|
|
dnl
|
|
dnl This is a sample configure.in
|
|
dnl Process this file with autoconf to produce a configure script.
|
|
dnl
|
|
dnl AC_INIT(UnTag.java)
|
|
dnl
|
|
dnl dnl Checks for programs.
|
|
dnl AC_CHECK_CLASSPATH
|
|
dnl AC_PROG_JAVAC
|
|
dnl AC_PROG_JAVA
|
|
dnl
|
|
dnl dnl Checks for classes
|
|
dnl AC_CHECK_RQRD_CLASS(org.xml.sax.Parser)
