Sorry, I only builded it in my machine and I dont have a 64 bits machine here to test. But You can get all source code at sourceforge and try to build it, I would be so happy to know if it works on 64bits too. Graciously,

you'll need also fpc to compile from source... but even so on 64 wont compile...: Compiling x86_64... /usr/bin/fpc -MObjFPC -Scgi -O1 -gl -WG -vewnhi -l -Fi. -Fu/usr/lib/lazarus/0.9.28.2/lcl/units/i386-linux/ -Fu/usr/lib/lazarus/0.9.28.2/lcl/units/i386-linux/gtk2/ -Fu/usr/lib/lazarus/0.9.28.2/packager/units/i386-linux/ -Fu. -FE. -oConversorMultimidia -dLCL -dLCLgtk2 ConversorMultimidia.lpr Hint: Start of reading config file /etc/fpc.cfg Hint: End of reading config file /etc/fpc.cfg Free Pascal Compiler version 2.4.0 [2010/01/08] for x86_64 Copyright (c) 1993-2009 by Florian Klaempfl Target OS: Linux for x86-64 Compiling ConversorMultimidia.lpr Fatal: Can't find unit Interfaces used by ConversorMultimidia Fatal: Compilation aborted

Hello, Did you installed lazarus-ide, libxml-simple-perl and fpc before compile the code?

I think I was who write that you'll need fpc to compile and lazarus&&fpc it depends one to another , anyway those are my detailes: [symbianflo@Mandriva2010_2 ~]$ rpm -q -i perl-XML-Simple lazarus fpc Name : perl-XML-Simple Relocations: (not relocatable) Version : 2.180.0 Vendor: Mandriva Release : 1mdv2010.1 Build Date: sab 08 mag 2010 20:26:45 CEST Install Date: sab 04 dic 2010 11:06:25 CET Build Host: n4.mandriva.com Group : Development/Perl Source RPM: perl-XML-Simple-2.180.0-1mdv2010.1.src.rpm Size : 157001 License: GPL+ or Artistic Signature : DSA/SHA1, mer 23 giu 2010 15:29:11 CEST, Key ID e7898ae070771ff3 Packager : Funda Wang <xxxxx@mandriva.org> URL : http://search.cpan.org/dist/XML-Simple/ Summary : Easy API to maintain XML (esp config files) Description : XML::Simple is a trivial perl API to manipulate XML. ** Name : lazarus Relocations: (not relocatable) Version : 0.9.29.27705 Vendor: Mandriva Release : 1mdv2010.2 Build Date: mar 28 dic 2010 15:10:52 CET Install Date: lun 28 feb 2011 08:58:05 CET Build Host: celeste.mandriva.com Group : Development/Other Source RPM: lazarus-0.9.29.27705-1mdv2010.2.src.rpm Size : 277669493 License: GPLv2+ and MPLv1.1 and LGPLv2+ with exceptions Signature : DSA/SHA1, mar 28 dic 2010 16:25:18 CET, Key ID dd684d7a26752624 Packager : Александр Казанцев <*********s@mandriva.org> URL : http://www.lazarus.freepascal.org/ Summary : Lazarus Component Library and IDE for Freepascal Description : Lazarus is a free and opensource RAD tool for freepascal using the lazarus component library - LCL, which is also included in this package. ******* Name : fpc Relocations: (not relocatable) Version : 2.4.0 Vendor: Mandriva Release : 1mdv2010.1 Build Date: ven 08 gen 2010 19:39:51 CET Install Date: sab 26 feb 2011 13:55:12 CET Build Host: klodia.mandriva.com Group : Development/Other Source RPM: fpc-2.4.0-1mdv2010.1.src.rpm Size : 199071778 License: GPLv2+ and LGPLv2+ with exceptions Signature : DSA/SHA1, mer 23 giu 2010 16:04:03 CEST, Key ID e7898ae070771ff3 Packager : Frederik Himpe <f*****@mandriva.org> URL : http://www.freepascal.org/ Summary : Free Pascal Compiler Description : The Free Pascal Compiler is a Turbo Pascal 7.0 and Delphi compatible 32bit Pascal Compiler.
