Thanks Charles. After reading your message I deleted cpptasks.zip and cpptasks.jar, ran the build again and it has worked. Perhaps it file only partially downloaded the first time through or something.
I can now get the build to complete successfully but I am still having issues. I expect these are probably more Fedora specific issues I need to try and work out somehow though.. First one I encountered was an SELinux message: SELinux is preventing java from loading /usr/local/harmony-jdk-798489/jre/bin/libhythr.so which requires text relocation. I disabled this and java -version now reports this which is encouraging: [and...@fedora11 helloworld]$ /usr/local/harmony-jdk-798489/bin/java -version Apache Harmony Launcher : (c) Copyright 1991, 2009 The Apache Software Foundation or its licensors, as applicable. java version "1.5.0" Apache Harmony (1.5.0) DRLVM (11.2.0) pre-alpha : not complete or compatible svn = r798489, (Jul 29 2009), Linux/ia32/gcc 4.4.0, release build http://harmony.apache.org [and...@fedora11 helloworld]$ But if I try and run or compile anything with it, it just spews out a whole lot of stuff ad infinitum such as: [and...@fedora11 helloworld]$ /usr/local/harmony-jdk-798489/bin/java HelloWorld Signal reported: GENERAL_PROTECTION_FAULT Registers: EAX: 0x092f6ff0, EBX: 0x006b5684, ECX: 0x092f6d6c, EDX: 0x00000013 ESI: 0x092f6d70, EDI: 0x092f7230, ESP: 0xbf87e874, EBP: 0xbf87e92c EIP: 0x006ace5d Command line: /usr/local/harmony-jdk-798489/jre/bin/java HelloWorld Working directory: /home/andrew/projects/helloworld Environment variables: ORBIT_SOCKETDIR=/tmp/orbit-andrew HOSTNAME=fedora11.localdomain IMSETTINGS_INTEGRATE_DESKTOP=yes TERM=xterm SHELL=/bin/bash Any ideas?
