The "Java issues" part isn't quite right. It turns out that the java 1.2 problem with the new gcj is really a bug in Ant, and there's already a patch in Ant trunk to fix it. So, to build with gcc-4.3 and Ant you'll need this patch: svn diff -r529854:529855 http://svn.apache.org/repos/asf/ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/compilers/DefaultCompilerAdapter.java ------------------------------------------------------------------------ r529855 | bodewig | 2007-04-18 05:17:52 +0100 (Wed, 18 Apr 2007) | 1 line Java 6's javac doesn't understand -source 1.1 either (found by Gump and the log4j build <http://gump.zones.apache.org/gump/test/logging-log4j-12/logging-log4j-12/gump_work/build_logging-log4j-12_logging-log4j-12.html>) ------------------------------------------------------------------------ Index: src/main/org/apache/tools/ant/taskdefs/compilers/DefaultCompilerAdapter.java =================================================================== --- src/main/org/apache/tools/ant/taskdefs/compilers/DefaultCompilerAdapter.java (revision 529854) +++ src/main/org/apache/tools/ant/taskdefs/compilers/DefaultCompilerAdapter.java (revision 529855) @@ -321,10 +321,10 @@ if (attributes.getSource() != null && !assumeJava13()) { cmd.createArgument().setValue("-source"); String source = attributes.getSource(); - if ((assumeJava14() || assumeJava15()) - && (source.equals("1.1") || source.equals("1.2"))) { + if (source.equals("1.1") || source.equals("1.2")) { // support for -source 1.1 and -source 1.2 has been - // added with JDK 1.4.2 - and isn't present in 1.5.0 either + // added with JDK 1.4.2 - and isn't present in 1.5.0 + // or 1.6.0 either cmd.createArgument().setValue("1.3"); } else { cmd.createArgument().setValue(source); Andrew. -- Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, UK Registered in England and Wales No. 3798903
