dnl The following commonly available Java macros converted to AX prefix
dnl in support of proper thrift/autoconf extension naming rules
dnl
dnl autoconf M4 macros for Java programs
dnl Copyright Stephane Bortzmeyer <bortzmeyer@pasteur.fr>, 1999
dnl Released under the GPL licence
dnl
dnl A sample configure.in is at the end of this file. Each macro is
dnl documented by comments before its definition. Here is a summary:
dnl
dnl AX_PROG_JAVAC: finds a Java compiler
dnl AX_PROG_JAVA: finds a Java virtual machine
dnl AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!)
dnl AX_CHECK_RQRD_CLASS: finds if we have the given class and stops otherwise
dnl AX_PROG_JAVAC tests an existing Java compiler. It uses the environment
dnl variable JAVAC then tests in sequence various common Java compilers. For
dnl political reasons, it starts with the free ones.
dnl If you want to force a specific compiler:
dnl - at the configure.in level, set JAVAC=yourcompiler before calling
dnl AX_PROG_JAVAC
dnl - at the configure level, setenv JAVAC
dnl You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
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 compilers (rationale: most Java programs cannot compile
dnl with some compilers like guavac).
AC_DEFUN([AX_PROG_JAVAC],[
test -z "$JAVAC" && AC_CHECK_PROGS(JAVAC, "gcj -C" guavac jikes javac)
test -z "$JAVAC" && AC_MSG_ERROR([no acceptable Java compiler found in \$PATH])
AX_PROG_JAVAC_WORKS
])
dnl AX_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 [AX_PROG_JAVAC] before.
dnl If you want to force a specific VM:
dnl - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA
dnl - at the configure level, setenv JAVA
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 TODO: allow to call this macro without [AX_PROG_JAVAC] before, using a
dnl class included uuencoded as an here document and uudecoded on the fly
dnl (check uudecode first) (rationale: a Java package can have no sources).
