If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc. You're using which OS? Groetjes, Berend (-: fido: 2:281/527.23 email: berend(a)beard.nest.nl

Units
by None 04 Jun '96

Hello, everybody! A known bug in GPC is that it does not automatically read Unit (or Module) interfaces when a Unit is used (or a Module is imported). For that reason, something like gpc -c myunit.pas gpc myprog.pas myunit.o -o myprog does only work when the main program (myprog.pas) (*$includes *) or #includes the Module interface. This is bearable with Extended Pascal where you can have the interface in a separate file; with Borland style Units you include the whole Unit, so it is recompiled each time. However, there is a workaround which is just another bug in GPC:-) A Borland style Unit with an empty implementation part but declaring some procedures in the interface part is not rejected by the compiler, only by the linker. Therefore, we can use the following trick: ---- file: myprog.pas ---- (*$I MyUnit *) (* Include the *whole* file MyUnit.pas *) Program MyProg; uses MyUnit; begin Hello; end. ---- file: myunit.pas ---- Unit MyUnit; Interface Procedure Hello; Implementation (*$ifdef IMPLEMENTATION *) (* suppress re-compilation of implementation part *) Procedure Hello; begin (* Hello *) writeln ( 'Hello!' ); end (* Hello *); (*$endif *) end. Now you can compile the Unit separately with gpc -D IMPLEMENTATION -c myunit.pas and then link it when compiling the main program via gpc myprog.pas myunit.o -o myprog Okay? Try it. Good luck! Peter
