By preference the java 12# compiler is gcj, then jikes then javac. 13# 14# The macro can take one argument specifying a space separated list of 15# java compiler names. 16# 17# For example: 18# 19# AX_PROG_JAVA_CC(javac, gcj) 20# 21# The macro also sets the compiler options variable: JAVA_CC_OPTS to 22# something sensible: 23# 24# - for GCJ it sets it to: @GCJ_OPTS@ 25# (if GCJ_OPTS is not yet defined then it is set to "-C") 26# 27# - no other compiler has applicable options yet 28# 29# Here's an example configure.in: 30# 31# AC_INIT(Makefile.in) 32# AX_PROG_JAVA_CC() 33# AC_OUTPUT(Makefile) 34# dnl End. 35# 36# And here's the start of the Makefile.in: 37# 38# PROJECT_ROOT := @srcdir@ 39# # Tool definitions. 40# JAVAC := @JAVA_CC@ 41# JAVAC_OPTS := @JAVA_CC_OPTS@ 42# JAR_TOOL := @jar_tool@ 43# 44# LICENSE 45# 46# Copyright (c) 2008 Nic Ferrier <nferrier@tapsellferrier.co.uk> 47# 48# This program is free software; you can redistribute it and/or modify it 49# under the terms of the GNU General Public License as published by the 50# Free Software Foundation; either version 2 of the License, or (at your 51# option) any later version. 52# 53# This program is distributed in the hope that it will be useful, but 54# WITHOUT ANY WARRANTY; without even the implied warranty of 55# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
