ac_prog_java_cc

Finds the appropriate java compiler on your path. By preference the java compiler is gcj, then jikes then javac.

The macro can take one argument specifying a space separated list of java compiler names.

For example:

  AC_PROG_JAVA_CC(javac, gcj)

The macro also sets the compiler options variable: JAVA_CC_OPTS to something sensible:

 - for GCJ it sets it to: @GCJ_OPTS@
   (if GCJ_OPTS is not yet defined then it is set to "-C")

 - no other compiler has applicable options yet

Here's an example configure.in:

  AC_INIT(Makefile.in)
  AC_PROG_JAVA_CC()
  AC_OUTPUT(Makefile)
  dnl End.

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

  PROJECT_ROOT      := @srcdir@
  # Tool definitions.
  JAVAC             := @JAVA_CC@
  JAVAC_OPTS        := @JAVA_CC_OPTS@
  JAR_TOOL          := @jar_tool@

# AC_PROG_JAVA_CC([COMPILER ...])
# --------------------------
# COMPILER ... is a space separated list of java compilers to search for.
# This just gives the user an opportunity to specify an alternative
# search list for the java compiler.

        [Define the compilation options for GCJ])
fi

])# AC_PROG_JAVA_CC
