I'm not totally clued up on this, but this is from the Help: "Library Page (Tools|Environment Options)
Library path = Specifies search paths where compiler can find the source files for the package. The compiler can find only those files listed in Library Path. If you try to build your package with a file not on the library path, you will receive a compiler error." These all seem to refer to packages, etc. "Directories/Conditionals (Project|Options) Search path = Specifies the location of your source files. Only those files on the compiler's search path or the library search path will be included in the build. If you try to build your project with a file not on the search path, you will receive a compiler error. You must include the entire search path. If you check Use Debug DCUs on the Compiler page of the Project|Options, the Debug DCU path (Tools|Debugger options|General page) is prepended to this search path." There is certainly a different emphasis in the help for these two. Might be worth looking into. Why things would suddenly stop working, I dunno... Cheers, Conor -----Original Message----- From: [EMAIL PROTECTED] It's the library path under Environment options I'm changing. The only search path I have (ever) had under directory / conditionals of the project, is "x:\dev_mnu" (where the dll gets created) and also the path to a shared_units folder, so that 2 projects share certain units, via the shared_units directory. Does that suggest anything?
