1 dnl @synopsis AC_PROG_JAVAC 2 dnl 3 dnl AC_PROG_JAVAC tests an existing Java compiler. It uses the environment 4 dnl variable JAVAC then tests in sequence various common Java compilers. For 5 dnl political reasons, it starts with the free ones. 6 dnl 7 dnl If you want to force a specific compiler: 8 dnl 9 dnl - at the configure.in level, set JAVAC=yourcompiler before calling 10 dnl AC_PROG_JAVAC 11 dnl 12 dnl - at the configure level, setenv JAVAC 13 dnl 14 dnl You can use the JAVAC variable in your Makefile.in, with @JAVAC@. 15 dnl 16 dnl *Warning*: its success or failure can depend on a proper setting of the 17 dnl CLASSPATH env. variable. 18 dnl 19 dnl TODO: allow to exclude compilers (rationale: most Java programs cannot compile 20 dnl with some compilers like guavac). 21 dnl 22 dnl Note: This is part of the set of autoconf M4 macros for Java programs. 23 dnl It is VERY IMPORTANT that you download the whole set, some 24 dnl macros depend on other. Unfortunately, the autoconf archive does not 25 dnl support the concept of set of macros, so I had to break it for 26 dnl submission. 27 dnl The general documentation, as well as the sample configure.in, is 28 dnl included in the AC_PROG_JAVA macro. 29 dnl 30 dnl @author Stephane Bortzmeyer <bortzmeyer@pasteur.fr> 31 dnl @version $Id: ac_prog_javac.m4,v 1.3 1999/12/29 10:46:15 bortz Exp $ 32 dnl 33 AC_DEFUN([AC_PROG_JAVAC],[ 34 AC_REQUIRE([AC_EXEEXT])dnl 35 if test "x$JAVAPREFIX" = x; then 36 test "x$JAVAC" = x && AC_CHECK_PROGS(JAVAC, "gcj$EXEEXT -C" guavac$EXEEXT jikes$EXEEXT javac$EXEEXT) 37 else 38 test "x$JAVAC" = x && AC_CHECK_PROGS(JAVAC, "gcj$EXEEXT -C" guavac$EXEEXT jikes$EXEEXT javac$EXEEXT, $JAVAPREFIX) 39 fi 40 test "x$JAVAC" = x && AC_MSG_ERROR([no acceptable Java compiler found in \$PATH]) 41 AC_PROG_JAVAC_WORKS 42 AC_PROVIDE([$0])dnl 43 ])
