dnl dnl The following commonly available Java macros converted to AX prefix dnl in support of proper thrift/autoconf extension naming rules dnl divert(-1) autoconf M4 macros for Java programs Copyright Stephane Bortzmeyer , 1999 Released under the GPL licence A sample configure.in is at the end of this file. Each macro is documented by comments before its definition. Here is a summary: AX_PROG_JAVAC: finds a Java compiler AX_PROG_JAVA: finds a Java virtual machine AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!) AX_CHECK_RQRD_CLASS: finds if we have the given class and stops otherwise divert(0) divert(-1) AX_PROG_JAVAC tests an existing Java compiler. It uses the environment variable JAVAC then tests in sequence various common Java compilers. For political reasons, it starts with the free ones. If you want to force a specific compiler: - at the configure.in level, set JAVAC=yourcompiler before calling AX_PROG_JAVAC - at the configure level, setenv JAVAC You can use the JAVAC variable in your Makefile.in, with @JAVAC@. *Warning*: its success or failure can depend on a proper setting of the CLASSPATH env. variable. TODO: allow to exclude compilers (rationale: most Java programs cannot compile with some compilers like guavac). divert(0) 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 ]) divert(-1) AX_PROG_JAVA tests an existing Java virtual machine. It uses the environment variable JAVA then tests in sequence various common Java virtual machines. For political reasons, it starts with the free ones. You *must* call [AX_PROG_JAVAC] before. If you want to force a specific VM: - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA - at the configure level, setenv JAVA You can use the JAVA variable in your Makefile.in, with @JAVA@. *Warning*: its success or failure can depend on a proper setting of the CLASSPATH env. variable. TODO: allow to exclude virtual machines (rationale: most Java programs cannot run with some VM like kaffe). TODO: allow to call this macro without [AX_PROG_JAVAC] before, using a class included uuencoded as an here document and uudecoded on the fly (check uudecode first) (rationale: a Java package can have no sources). divert(0) AC_DEFUN([AX_PROG_JAVA],[ test -z "$JAVA" && AC_CHECK_PROGS(JAVA, kaffe java) test -z "$JAVA" && AC_MSG_ERROR([no acceptable Java virtual machine found in \$PATH]) AX_PROG_JAVA_WORKS ]) divert(-1) AX_CHECK_CLASS tests the existence of a given Java class, either in a jar or in a '.class' file. *Warning*: its success or failure can depend on a proper setting of the CLASSPATH env. variable. divert(0) AC_DEFUN([AX_CHECK_CLASS],[ CLASS=$1 echo -n "Testing if we have Java class $CLASS...
