The problem can well be that lhelp needs to be adapted.
Yes, as I said, I agree with that.
In \components\chmhelp\lhelp\lhelpcore.pas (patched with [1] but
shouldn't really matter), if I do
uses
...lazloggerbase, lazlogger...
procedure THelpForm.ServerMessage(Sender: TObject);
var
BytesRead: LongInt;
UrlReq: TUrlRequest;
FileReq: TFileRequest;
ConReq: TContextRequest;
MiscReq: TMiscRequest;
MustClose: boolean=false;
Stream: TStream;
Res: LongWord;
Url: String='';
begin
if fInputIPC.PeekMessage(5, True) then begin
Res := Ord(srError); //fail by default
Stream := fInputIPC.MsgData;
Stream.Position := 0;
FillByte(FileReq{%H-},SizeOf(FileReq),0);
BytesRead := Stream.Read(FileReq, SizeOf(FileReq));
if BytesReadSizeOf(FileReq) then
begin
debugln('lhelpcore error: expected at least
filereq('+inttostr(SizeOf(FileReq))+' bytes); got '+inttostr(BytesRead));
exit;
end;
case FileReq.RequestType of
rtFile: begin
Url := 'file://'+FileReq.FileName;
Res := OpenURL(URL);
debugln('lhelpcore: got rtfile, filename
'+filereq.filename);
end;
the log shows
lhelpcore error: expected at least filereq(520 bytes); got 0
so seems like an empty message.
HTH,

[Lazarus] Laz trunk+FPC trunk Windows - experiences with help
Hi list, I'm getting a lot of errors trying to get context-sensitive help with lhelp. (in my patched copy of Lazarus; see second patch in http://bugs.freepascal.org/view.php?id=24743) Lhelp will start up but give Cannot handle this type of subcontent: file:// for url: file:// It looks like the actual file name of the chm file is not being received by lhelp. Normally I would always blame the compiler and/or RTL/FCL for my own or other people's incorrect code ;) but I'm starting to suspect recent fixes in simpleipc may have messed things up. I'm going to have a look at that but first wanted to know whether other people with the config listed in the subject have the same issues (or whether it's PEBKAC/machine dependent). Alternatively, review and correction of the patch in http://bugs.freepascal.org/view.php?id=24743 would be very welcome, too ;) Finally, I would be grateful if somebody could indicate if my patch works for FPC trunk+Lazarus trunk?
