This compiler message looks strange to me: "tatextelements.pas(177,24) Hint: Value parameter "AValue" is assigned but never used". It occurs when TAChart is recompiled (see bug report #0027484). Here is the corresponding code:

procedure TGenericChartMarks.SetFrame(AValue: _TFramePen);
begin
   if FFrame = AValue then exit;
   FFrame.Assign(AValue);
   StyleChanged(Self);
end;

I would say that the parameter "AValue" *is* used. So, what is this hint for?

What compiler version? If 2.6.x please retest with a 3.x version. If it is still reproducible then try to reproduce it in a smaller, self contained example and report as a bug for FPC.

This is a generic class. The compiler does not know at this point what _TFramePen is. The hint sounds like a compiler bug. Please report to FPC.

1.4RC1 is built with 2.6.4.

If 2.6.x please retest with a 3.x version. If it is still reproducible then try to reproduce it in a smaller, self contained example and report as a bug for FPC.

Thank you, fpc trunk does not show the hint.

The bug report mention in the first post refers to another set of compilation messages which I do not understand:
"tachartlazaruspkg.pas(18,23) Verbose: Unit "TAFitUtils" not used in TAChartLazarusPkg". I cannot reproduce this, neither in fpc 2.6.4 nor fpc trunk. Is this due to some non-standard compilation message parameters used by the OP?

The original message comes from FPC and is a hint. Each package has an option (Compiler Options / Verbosity / Show hints for unused units in main), which is off by default. The IDE changes the "Hint" into a mere "Verbose".
By default the Messages windows does not show "Verbose" messages.

You can change the filter:
Right click on "Messages" window, then "Filter non urgent messages".

The bug submitter has turned the filter off. This filter is a new feature of 1.4. With the default settings you see the same as in Lazarus 1.2.
