Yes: 1) Have sources of the two programs in different folders (directories) and start the text-mode IDE in the respective folder depending on the "project" / program you intend to build. 2) Set the compiler defines as necessary for the respective "project" (i.e. differently for ProgramA when started from directory of ProgramA and for ProgramB when started from directory of ProgramB) - Options -> Compiler -> Conditional defines. By default, the configuration is automaticaly saved when exiting the IDE. 3) Make sure you always rebuild the unit depending on the program you want to compile (Compile -> Build). Obviously, this requires the source file of the unit to be available for the compiler (i.e. in one of paths in Options -> Directories -> Unit directories). >>There are already many ways to add defines.

The hard thing is for the user to understand differences among the available options and their implications. Defines have impact only when compiling the particular source code. Having a 'global define' in a program could never have impact to a unit which might be already compiled using different defines at the moment the particular program is compiled. One of possible solutions for this is having a 'global include file' which is included in all the relevant units and the program, the other is outlined above (defines stored in the compiler / IDE configuration file). >>If you want a compiler define for all projects, then simply add that >> define in your fpc.cfg file. That is a "global options" file.

Not quite - the text-mode IDE doesn't invoke fpc.exe binary (it has the compiler built-in) and it passes the options as defined in the respective IDE dialogs. > Thanks for explaining that.

Yes (if starting the _compiler_ in that directory). If using the IDE, you can do the same with the fp.cfg file. > I'm wondering if I am missing something with reference to 'projects' is > that a Lazarus thing? How are 'projects' defined? Yes, projects are 'a Lazarus thing'. However, you can achieve a similar effect with local options and configuration files for the text-mode IDE (you just need to use different directories for different 'projects').
