[fpc-pascal] FPC happily eats wrong parameters
Hi, When calling fpc -d foo test.pas there are two mistakes: First the -d parameter is missing a value, which fpc silently ignores. And second there are two files to compile. FPC ignores that too, gives a hint, but compiles anyway. Design or bug? Mattias ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Accepting an empty -d parameter sounds like a bug though. Jonas___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

The '-d' argument is written explicitely to do something only if it has a (directly following) argument. Otherwise it does nothing. If this should be considered a bug or not is up to discussion, but the code is this way at least since the migration to SVN. That FPC warns if multiple files are supplied is by design as there is a specific warning about this. FPC will always use the last filename given as mentioned here: http://www.freepascal.org/docs-html/user/userse70.html#x182-189000C.11 Regards, Sven ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

You are right, it is a warning. Why not an error? In what case do you need to pass two files to the compiler?

It would be a nice feature, if fpc does not let the user shoot his foot this way. That FPC warns if multiple files are supplied is by design as there is a specific warning about this. FPC will always use the last filename given as mentioned here: http://www.freepascal.org/docs-html/user/userse70.html#x182-189000C.11 Yes, it is this way since at least 2000. I assumed that eventually fpc will support compiling multiple files. But I guess this will not happen, so maybe it would be better to change the warning to an error. A warning is defined as something that is probably wrong, but may be needed in some cases. Where is the need for passing files that the compiler ignores?
