# SYNOPSIS
|
|
#
|
|
# AC_PROG_JAVA_CC
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# 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@
