Hi, it´s me, the guy with this internal error recently, while porting
OpenXML to FP. Meanwhile, the compiler switch -B did help me out.
Apparently by compiling all units, regardless wether they have been changed
or not, this internal error is avoided. Now I believe this B stands for
Back to hell, since there are other surprises with duplicate identifiers,
where I never thought it could happen, see the following example.
unit xdom31;
uses
... xmltreeutils, ...
type
TDomNode = class (TDomCustomNode)
private ...
protected ...
public ...
property NamespaceURI: WideString read GetNamespaceURI; ...
TDomCharacterData = class (TDomNode)
private ...
protected ...
public ...
function SubstringData(const Offset, Count: Integer): WideString; virtual;
// FPC: identifier COUNT already defined in unit xmltreeutils at line 98
procedure ReplaceData(const Offset, Count: Integer) ...
// FPC: identifier COUNT already defined in unit xmltreeutils at line 98
...
TDomAttr = class (TDomNode)
private ...
protected ...
public ...
constructor CreateNS(
const AOwner: TDomDocumentNS;
const NamespaceURI ...
// FPC: identifier NamespaceURI already defined at line 1192
...
unit xmltreeutils;
...
type
TCustomOwnedNode = class(TCustomOwnedObject)
private ...
protected ...
property Count: Integer read GetCount;
...
Conclusion: never call any parameter of any procedure or function exactly
like any property of any class and its ancestors. So far I thought,
parameter names of functions and procedures are always local, i.e. valid
for this function or procedure block only. Is this a bug or feature of FPC
vs. Delphi?
Disclaimer: I love all FPC warnings and hints. Each may be an unknown error
less. In or in front of the machine.
