Hi, I compile FPC with success using my tutorial: http://wiki.freepascal.org/Installing_Lazarus#Compiling.2Finstalling_FPC_and_Lazarus_from_Sources_of_SVN_.28Win32.29 Questions: 1- How can I compile all packages with DEBUG option? 2- How can I compile just one package, eg fcl-xml, with DEBUG option? Thanks, Marcos Douglas
