Can't install WST (Web Service Toolkit)
lazarus / 38-Networking and Web Programming

Hi there everyone,

I just downloaded the SVN version of the WST by Inoussa Ouedraogo from
https://lazarus-ccr.svn.sourceforge.net/svnroot/lazarus-
ccr/wst/trunk/.

However I cannot install the package because of an error in
pascal_parser_intf.pas. The error says C:\Lazarus\components_extra\Web
ServiceToolkit\ws_helper\pascal_parser_intf.pas(556,18) Error:
Incompatible types: got "TFPList" expected "TList"

Code: [Select]function GetParameterIndex(
        AProcType  : TPasProcedureType;
  const AParamName : string;
  const AStartPos  : Integer
) : Integer;
var
  pl : TList2;
  i : Integer;
begin
  pl := AProcType.Args;                                    <======
ERROR OCCURS HERE
  if ( AStartPos >= 0 ) then
    i := AStartPos
  else
    i := 0;
  for i := i to Pred(pl.Count) do begin
    if AnsiSameText(AParamName,TPasArgument(pl[i]).Name) then begin
      Result := i;
      Exit;
    end;
  end;
  Result := -1;
end;

Has anyone successfully installed the WST recently?

Are you indeed using FPC 2.6.1? I would guess that you're stuck
between versions. The conditional code in pascal_parser_intf.pas is
defining wst_use_fplist if this is true:

(FPC_VERSION = 2) and (FPC_RELEASE > 6)

With 2.6.1, release should still be 6. Maybe the change of args from
TList to TFPList in pasparser.pp (fcl_passrc) has been backported to
2.6.1 or something, thus breaking this code. Add something like this
(not tested):

(FPC_VERSION = 2) and (FPC_RELEASE = 6) and (FPC_PATCH > 0)

And report this to WST forum so Innousa can fix it.

Or use FPC 2.6.0 or trunk instead of 2.6.1.

Thanks.

Depending on the code (haven't looked at it), this may be a better fit
to match 2.6.1, 2.6.2, 2.7.1, 2.8, 3.0 etc:
Code: [Select]{$IF FPC_FULLVERSION>=20601} //FPC 2.6.1 or higher

I am indeed using FPC 2.6.1 because of issues I had with the
fpspreadsheet package which threw up compiler errors on FPC 2.6.0

So I can't go back to FPC 2.6.0

Thanks for the links Stefano. Looks like I'll have to wait a while for
the bugs to be sorted out.

I see from today's WST commits that the problem with TFPList should be
fixed.

Thanks.
