Delphi Package: "The following changes must be made..." never goes away - delphi

On one of my packages, which was adapted from another using Save-As and edit, I keep getting the following message (this is in Delphi 2007):
=======
The following changes must be made before this package can be compiled.
Choose OK to apply these changes and continue compiling.
Remove cmSizePanel_Reg.
Unit(s) cmSizePanel_Reg were found in required package cmExtRzPanel_D2007.
=======
I click OK, and it then proceeds to compile fine. This message, however, never goes away -- I get it every time I compile the package.
Here is the project source, using right-click, "View Source" to get there:
package cmBaseFrames_D2007;
{$R *.res}
{$ALIGN 8}
{$ASSERTIONS ON}
{$BOOLEVAL OFF}
{$DEBUGINFO ON}

cmBaseFrameFrame in 'cmBaseFrameFrame.pas' {cmBaseFrame: TFrame},
cmBaseSizeableFrameFrame in 'cmBaseSizeableFrameFrame.pas' {cmBaseSizeableFrame: TFrame};
end.
"cmSizePanel_Reg" isn't in the project anymore, and doesn't show up in teh Project Manager panel. It would appear that it's "hiding" somewhere in one of the file Delphi uses for the package, but I'm not seeing where. Any ideas how to stomp out this little inconvenience without having to complete re-create the package from scratch?

Try looking through the XML of your .dproj for the package. .dproj files have a knack for getting corrupted and becoming out of sync with the file list in the DPR, leading to strange problems like this.

Stale .dcp files maybe? They are the compliment to .BPL packages and contain descriptions about the BPL.

Make a VCL package 64-bit compatible

I noticed that in a 64 bit application, the VCL Design components I have written are grayed-out in the component pallette:
Other third party VCL components work in both 32 and 64 bit.
My BPL can compile in 32-bit and 64-bit mode. There is no code that requires 32 bit only. What can I do to unlock the components to 64 bit applications?
The BPL source code of the VCL component is:
package ......;
{$R *.res}
{$IFDEF IMPLICITBUILDING This IFDEF should not be used by users}
{$ALIGN 8}
{$ASSERTIONS ON}
{$BOOLEVAL OFF}
{$DEBUGINFO ON}
{$EXTENDEDSYNTAX ON}
{$IMPORTEDDATA ON}

{$OPTIMIZATION ON}
{$OVERFLOWCHECKS OFF}
{$RANGECHECKS OFF}
{$REFERENCEINFO ON}
{$SAFEDIVIDE OFF}
{$STACKFRAMES OFF}
{$TYPEDADDRESS OFF}
{$VARSTRINGCHECKS ON}
{$WRITEABLECONST OFF}
{$MINENUMSIZE 1}
{$IMAGEBASE $400000}
{$ENDIF IMPLICITBUILDING}
{$DESCRIPTION '......'}
{$IMPLICITBUILD OFF}
requires
rtl,

vclx,
adortl,
dbrtl,
vclactnband,
xmlrtl,
vcldb,
Jcl,
vclie;
contains
HsGauge in 'HsGauge.pas',
.......
end.
I noticed that I cannot install the component when it is compiled in 64 bit (I'm not sure if that is the reason):
32 bit:
64 bit:
IDE is a win32 program so it can load only win32 dlls and win32 bpls, so you can’t install win64 bpl.
By default – all must work correctly and we develop a lot of components, so you broke something by your code.
In the modern version of Delphi there is a special attribute for the class that specifies the target platform for your component - “ComponentPlatformsAttribute”.
So, if you write something like:
[ComponentPlatformsAttribute(pidWin32 or pidWin64)]
TMyButton = class(TButton)
End;
This component will be valid for Win32 and Win64 platforms, but not valid (gray) for Android, IOS etc.. Try to find a solution there.
Read more https://docwiki.embarcadero.com/Libraries/Alexandria/en/System.Classes.ComponentPlatformsAttribute
P.S. If it does not help – try to create a simple bpl with a simple sample component and try to use it in win64. If it works – compare settings of this BPL with your not workable BPL. Then move differences one by one into sample BPL until that will stop working. There how you find out what’s wrong.
Delphi IDE is a 32 bit application and need 32 bit packages to be able to use components at design time.
Your 64 bit application need a 64 bit run-time package, that's why Delphi can build 64 bit packages.
If you don't use run-time package in your application then there is no need to create one.

As soon as I change Project Options > Building > Delphi Compiler > DCP output directory to ..\..\..\Delphi 10.3\DCP\$(Platform)\$(Config) the DPK is changed to:

Does anyone have an idea why this happens? Can it be prevented without doing manual edits to the DPK file? It is something I noticed in XE3 as well.
I noticed the following on the Indy instructions page:
Note for Cross-Platform compiling:
The current Indy 10 package projects are set for Windows compilations.
The IndySystem and IndyProtocols packages do have a few
platform-specific units in them, which are conditionally compiled via
IFDEF statements in the DPK files. This is fine for command-line
compilations, but the IDE usually doesn't handle IFDEFs in DPK files
very well, and this can also cause an associated DPROJ file to be out
of sync with its DPK file. So this may lead to issues if you want to
compile Indy 10 via the IDE for non-Windows platforms (in Delphi
versions that support this). You might need to edit the IndySystem
project to remove the IFDEFs and replace the IdStackWindows,
IdWinsock2, and IdWship6 units with the IdStackVCLPosix and
IdVCLPosixSupplemental units instead, and then edit the IndyProtocols
project to remove the IFDEFs and the IdAuthenticationSSPI and IdSSPI
units. Perhaps in a future release, we will try to automate/cleanup
this better.
It may say So this may lead to issues if you want to compile Indy 10 via the IDE for non-Windows platforms but I suspect I will have to paste the DPK code back after changing the Options.
That looks more like the "well-known" issue with mixed line breaks.
Probably the original file has unix endings and the change in the IDE converts some lines to PC endings.

Resource in Designer ok, Runtime exception eresnotfound in module [duplicate]

This question already has answers here:
How to add and use a resource from a custom package/component in Delphi?
(3 answers)
Closed 3 years ago.
I am trying to add a few images to my new component. So I did this
Project -> Resource and Images
Added a new Resource
Filename : Logo.png
Type : RCDATA
Identifier : LOGO
On the Constructor I do this :
OptionsImage.Glyph.LoadFromResource(HInstance,'Logo',RT_RCDATA);
OptionsImage.Glyph.SourceHeight:=24;
OptionsImage.Glyph.SourceWidth:=24;
In Designer this works flawlessly. But if I try to run this ... I get the
error :
Exception EResNotFound in module Project1.exe at 00074128.
Resource LOGO not found.
Why is it not finding the Logo at run time ?
Thank you for the kind help.
UPDATE 1 :
I have a GridButton.bpl in this I have on top
{$R *.res}
{$R *.dres}
With this alone , the Designer is working correctly, but If I try to run I get the error.
Now If I add to the Unit : cxGridButton.pas the same lines
{$R *.res}
{$R *.dres}
I recieve a Warning that I have duplicate resources . But now it works in Designtime and Runtime.
I must be doing something horribly wrong. But what ?
UPDATE 2
The other question is the same yes, but the answers are not working.
Meanwhile I solved it but I do not understand why is it working now.
GridButton.bpl
package GridButton;
{$R *.res}
{$IFDEF IMPLICITBUILDING This IFDEF should not be used by users}
{$ALIGN 8}
{$ASSERTIONS ON}
{$BOOLEVAL OFF}
{$DEBUGINFO OFF}
{$EXTENDEDSYNTAX ON}
{$IMPORTEDDATA ON}
{$IOCHECKS ON}
{$LOCALSYMBOLS OFF}
{$LONGSTRINGS ON}
{$OPENSTRINGS ON}
{$OPTIMIZATION ON}
{$OVERFLOWCHECKS OFF}
{$RANGECHECKS OFF}
{$REFERENCEINFO OFF}
{$SAFEDIVIDE OFF}
{$STACKFRAMES OFF}
{$TYPEDADDRESS OFF}
{$VARSTRINGCHECKS ON}
{$WRITEABLECONST OFF}
{$MINENUMSIZE 1}
{$IMAGEBASE $400000}
{$DEFINE RELEASE}
{$ENDIF IMPLICITBUILDING}
{$IMPLICITBUILD ON}
requires
*******;
contains
cxGridButton in 'cxGridButton.pas';
end.
And the Unit itself has
implementation
{$R GridButton.dres}
Now it works at Designtime and at Runtime . Is there a Bug in the Resource Manager or I did something wrong ? Can someone please explain.
The resources added via Project -> Resource and Images are compiled into a separate resource file name .dres. This resource file has to be mentioned in the DPR. Usually the IDE takes care of adding this file, but that may somehow missing in your case.
Things are a bit more complicated when you compile outside the IDE - say on a build server. In that case you have to take care of creating the DRES file yourself.

Delphi XE2: What is the purpose of IMPLICITBUILDING directive found in package

When I attempt to create a new package in Delphi XE2, there is a new construct in package dpk source file: IMPLICITBUILDING
What is that for?
package Package1;
{$R *.res}
{$IFDEF IMPLICITBUILDING This IFDEF should not be used by users}
{$ALIGN 8}
{$ASSERTIONS ON}
{$BOOLEVAL OFF}
{$DEBUGINFO ON}
{$EXTENDEDSYNTAX ON}
{$IMPORTEDDATA ON}
{$IOCHECKS ON}
{$LOCALSYMBOLS ON}
{$LONGSTRINGS ON}
{$OPENSTRINGS ON}
{$OPTIMIZATION OFF}
{$OVERFLOWCHECKS OFF}
{$RANGECHECKS OFF}
{$REFERENCEINFO ON}
{$SAFEDIVIDE OFF}
{$STACKFRAMES ON}
{$TYPEDADDRESS OFF}
{$VARSTRINGCHECKS ON}
{$WRITEABLECONST OFF}
{$MINENUMSIZE 1}
{$IMAGEBASE $400000}
{$DEFINE DEBUG}
{$ENDIF IMPLICITBUILDING}
{$IMPLICITBUILD ON}
requires
rtl;
end.
Please also see this discussion: Why does Delphi change Indy's dpk source file when I change project options and this.
"The compiler directives which appear between the $IFDEF IMPLICITBUILDING
and $ENDIF are normally passed as parameters by the compiler when
explicitly compiling a package. Because these options change based on
the configuration (debug / release) and target platform (Win32, Win64,
OSX32) it's problematic to have them statically defined in the package
project source. When defined in the project source they will always
override the options passed by the compiler. The $IFDEF prevents these
options from being used during explicit compilation.
In cases where a package is implicitly compiled these options will be
used, but unless your project was saved in the configuration / target
mode you want to compile for, you may not get the results you expect.
As a general rule, it's better to disable implicit building on packages
and compile them explicitly via a project group build or through project
dependencies. If you are building for only a single platform using a
single configuration then the implicit building mechanism is adequate.
IMPLICITBUILDING is defined by the compiler during the compilation of a
package that is being implicitly compiled as part of the compilation of
something that depends on it. As indicated in the comment you should
not be trying to define this value yourself"
I assume it is related to the {$IMPLICITBUILD ON} flag below the conditional block. I guess that it is set as long as the compiler is performing the implicit build (compared to an explicit build). I have no idea why the settings should only be regarded if that is the case. It is certainly not documented yet.

Identifiers for Delphi's $WARN compiler directive

Delphi has a $WARN compiler directive that allows one to selectively enable or disable specific warnings. The Delphi 2009 help file describes the syntax:
{$WARN identifier ON|OFF}
But it only lists the identifiers for 6 warnings.
I'd like to have a complete list of all the warning identifiers. In particular, I want to know the identifiers for the implicit string cast warnings W1057 and W1058 in Delphi 2009.
I managed to guess the one for implicit Ansi->Unicode casts (W1057):
{$WARN IMPLICIT_STRING_CAST OFF}
Googling for that found me the other one:
{$WARN IMPLICIT_STRING_CAST_LOSS OFF}
Though that solves my immediate need, I'd still like to know the complete list of warning identifiers. Stuff like this should be documented.
Darian's right that the DCCStrs.pas lists the identifiers used by the Delphi compiler. It hadn't occurred to me to search the source, since Delphi doesn't include the source to its compiler.
I've extracted the identifiers for hints and warnings from that file:
{$WARN ASG_TO_TYPED_CONST OFF}
{$WARN BAD_GLOBAL_SYMBOL OFF}
{$WARN BOUNDS_ERROR OFF}
{$WARN CASE_LABEL_RANGE OFF}
{$WARN COMBINING_SIGNED_UNSIGNED OFF}
{$WARN COMPARING_SIGNED_UNSIGNED OFF}
{$WARN COMPARISON_FALSE OFF}
{$WARN COMPARISON_TRUE OFF}
{$WARN CONSTRUCTING_ABSTRACT OFF}
{$WARN CVT_ACHAR_TO_WCHAR OFF}
{$WARN CVT_NARROWING_STRING_LOST OFF}
{$WARN CVT_WCHAR_TO_ACHAR OFF}
{$WARN CVT_WIDENING_STRING_LOST OFF}
{$WARN DUPLICATE_CTOR_DTOR OFF}
{$WARN DUPLICATES_IGNORED OFF}

{$WARN XML_EXPECTED_CHARACTER OFF}
{$WARN XML_INVALID_NAME OFF}
{$WARN XML_INVALID_NAME_START OFF}
{$WARN XML_NO_MATCHING_PARM OFF}
{$WARN XML_NO_PARM OFF}
{$WARN XML_UNKNOWN_ENTITY OFF}
{$WARN XML_WHITESPACE_NOT_ALLOWED OFF}
{$WARN ZERO_NIL_COMPAT OFF}
I looked through the help and didn't see a full list...so poking around the code it appears the compiler warning constants are all listed in:
CodeGear\RAD Studio\6.0\sources\toolsapi\DCCStrs.pas
Search for "Implicit_String_Cast_Loss" and you'll see the constant
sIMPLICIT_STRING_CAST_LOSS = 'DCC_IMPLICIT_STRING_CAST_LOSS';
I would assume the rest of the DCC_xxx strings with corresponding X_true/_false/_error defines are what you are after.
Online help hasn't been very good since Delphi 7.
Something else not mentioned in the Delphi 2009 documentation:
The $WARN directive now has a 3rd option ERROR in addition to ON and OFF. So you can have:
{$WARN IMPLICIT_STRING_CAST OFF} to disable the warning
{$WARN IMPLICIT_STRING_CAST ON} to enable warning
{$WARN IMPLICIT_STRING_CAST ERROR} to turn the warning into an error
Stuff like this should be documented
As of today, the full list of identifiers and their compiler warning numbers are listed in the documentation at:
http://docwiki.embarcadero.com/RADStudio/en/Warning_messages_(Delphi)
Excerpt:
The identifier in the $WARN directive can have any of the following values:
| Warning | Identifier |
|:-----------------:|:----------:|
| SYMBOL_DEPRECATED | W1000 |
| SYMBOL_LIBRARY | W1001 |
| (...) | (...) |
If you press Ctrl+O twice it will add all the compiler directives to the top of the unit including all the warnings. Find the one you want and delete the rest.
