Delphi: When porting really old code from versions that did not have .dproj files, watch your .dfg and .dof files

Posted by jpluimers on 2021/06/10

I have been bitten by this a few times too much, so time to write it down:

When porting old Delphi code from the Delphi 7 and older era, the options were stored .dof (options) and .cfg (configuration) files.

More modern Delphi versions try to translate these files when generating the .dproj file, in a similar way as they try to upgrade older .dproj files to newer formats.

Many things can go wrong, including these ones I have bumped into multiple times:

  • DCC_DebugInformation having a 0 or false value, but not handling these values correctly (I remember problems around the Delphi XE5 era with this: When the Delphi XE5 commandline compiler fails with error F1026: File not found: ‘False.dpr’)
  • DCC_OutputDependencies not being adhered to (no .d file is being emitted by the compiler), though for the .drc files, DCC_OutputDRCFile works fine)
  • DCC_DebugInformation having a 1 value (Limited Debug information) instead of being absent (Debug information)
  • DCC_SymbolReferenceInfo having a 1 value (Definitions Only) instead of being absent (Reference info)
