dnl @synopsis AC_PROG_JAVA_CC

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 dnl End.

dnl

dnl And here's the start of the Makefile.in:

dnl

dnl PROJECT_ROOT := @srcdir@

dnl # Tool definitions.

dnl JAVAC := @JAVA_CC@

dnl JAVAC_OPTS := @JAVA_CC_OPTS@

dnl JAR_TOOL := @jar_tool@
