Hi!
The lines above do compile and work fine under previous versions of FPC. With the latest version of FPC I got the following error message:

Free Pascal Compiler version 1.9.5 [2004/11/24] for i386
dfTools.pas(107,11) Error: Can't declare procedure as EXTERNAL

Has there something changed?

2nd Problem:
-------------------------------------------------- The line
-Fud:\fpc/units/i386-$TARGET/*
won't be regonized correctly. The path is not found by FPC. Instead I have to write
-Fud:\fpc/units/i386-win32/*
That seems to be broken. ???

Yes, there is also a declaration in the interface. You can't declare a procedure external in the implementation anymore when the interface says that is needs to have a body. There is an exception for win32 and os/2 regarding to DLL imports.

Mail was send to fpc-devel for this change

interface
procedure dfCrap(setoperation: Tso); cdecl;
implementation
{$LINK dfc.ow}   //GCC object file style
procedure dfCrap(setoperation: Tso); cdecl; external;
...

The declaration does exist in the interface!
BTW: I am working under Win32.

just move what you presently have in the implementation to the interface and remove what you currently have in the interface

Yes, that's the problem. You either need to remove the declaration from interface altogether, or move the complete declaration including import specification from implementation to interface.

BTW: I am working under Win32.

However, you don't import the procedure from a DLL - see Peter's e-mail below.

You aren't importing from a DLL, so Win32 has the same rules.

The problem is that the interface declaration sets the assembler name to something like U_UNITNAME_DFCRAP$TSO. The implementation declaration changes the assembler name to _dfCrap. This gives problems when the procedure was already called (from other units) before the implementation declaration is parsed.

You cannot declare procedures in the interface section.
