Hi,

Thank you for your feedback.

At first glance, the F2084 Internal Error: LC2240 seems more like an internal Delphi compiler issue on the OSXARM64 target, rather than a direct error in the code.

The line indicated in GenAI.pas appears to be where the compiler failed, but this isn't necessarily the cause.
For now, I suggest you try the following, as this will help me refine my diagnosis:

- Close Delphi;
- Delete the project's output folders for OSXARM64, specifically OSXARM64\Debug and OSXARM64\Release;
- Delete any old generated files related to this target, including .dcu, .o, and temporary files;
- Reopen Delphi and run a full build, not just a compile.

You can also try adding this to the very beginning of GenAI.pas, right after:

unit GenAI;

{$IFDEF MACOS}
  {$IFDEF CPUARM64}
    {$INLINE OFF}
  {$ENDIF}
{$ENDIF}

The idea here is to disable inlining only for macOS ARM64, because this type of target uses the LLVM backend and can sometimes trigger this kind of internal error.

There are also quite a few warnings related to deprecated symbols. In future updates, they will disappear because I will remove the deprecated units.

But normally, this shouldn't block compilation, however, in this context, with a large unit and many type aliases, it could potentially contribute to the problem.

To quickly test this approach, you can temporarily add the following after unit GenAI;:

{$WARN SYMBOL_DEPRECATED OFF}

This does not modify the library's behavior; This just lets you see if the compiler can proceed further.

Finally, also check that Delphi 12 Athens is up to date with the latest available patches.

If the error persists despite this, I'll look into adapting GenAI.pas to avoid certain type aliases in public signatures, as this is a pattern that can trigger this type of error on ARM64 compilers.

For example:

function FromDeveloper(...): GenAI.Chat.TMessagePayload;

[VBilovus2002]

Hi,
Thanks for the quick response.

I followed all your recommendations but it didn't help in any way.
The same error occurs during compilation.
In the IDE, the cursor is positioned in GenAI.pas on the line:
function FromDeveloper(const Content: string; const Name: string = ''):TMessagePayload;

The error message:

[dccosxarm64 Fatal Error] GenAI.pas(4631): F2084 Internal Error: LC2240

Hi,

I have another hypothesis to check before changing the repository.

The issue probably does not come from FromDeveloper itself, but rather from the large facade unit GenAI.pas. This unit exposes a large number of type aliases in its interface, for example:

TDeletion = GenAI.API.Deletion.TDeletion;

It is possible that the OSXARM64 compiler is hitting a limitation or an internal bug related to this accumulation of aliases and fully qualified type references in a single unit.

Could you run a local test by temporarily commenting out the type-alias block in GenAI.pas, while still keeping GenAI as the SDK entry point?

Expected consequence: if your code relied on some types through these aliases, you may need to add the corresponding units directly to the uses clauses of your own units, for example GenAI.Chat, GenAI.API.Deletion, GenAI.Models, etc., depending on the types actually used by your project.

What I am mainly interested in is the result of the OSXARM64 build after removing that block:

• if the compiler gets past this point, or if the error changes, that would strongly point to the alias block;
• if the error remains strictly identical, we can rule out this hypothesis.

This is only a diagnostic test. If it confirms the hypothesis, I will look into how to make the facade unit lighter without breaking the current SDK usage.

[VBilovus2002]

Hello.

I checked your hypothesis on your test project TestGenAI_FMX.

1. In the façade module GenAI.pas, I commented out all interface aliases, for example:

TDeletion = GenAI.API.Deletion.TDeletion;`

2. In the module GenAI.Tutorial.FMX.pas, I added the following units directly to the uses clause:

 GenAI.API.Params,
 GenAI.API.Deletion,
 GenAI.Models,
 GenAI.Functions.Core, GenAI.Batch.Interfaces, GenAI.Schema, GenAI.Embeddings,
 GenAI.Audio, GenAI.Chat, GenAI.Moderation, GenAI.Images, GenAI.Files, GenAI.Uploads,
 GenAI.Batch, GenAI.Batch.Reader, GenAI.Batch.Builder, GenAI.Completions, GenAI.FineTuning,
 GenAI.Vector, GenAI.VectorFiles, GenAI.VectorBatch, GenAI.Monitoring, GenAI.Chat.Parallel,
 GenAI.Responses, GenAI.Responses.InputParams, GenAI.Responses.InputItemList,
 GenAI.Responses.OutputParams, GenAI.Async.Promise, GenAI.Responses.Internal,
 GenAI.Conversations, GenAI.Video, GenAI.Containers, GenAI.ContainerFiles,
 GenAI.NetEncoding.DataURI, GenAI.Gemini.Extra_body,
 GenAI.Assistants, GenAI.Threads, GenAI.Messages, GenAI.Runs, GenAI.RunSteps

3. For macOS, in GenAI.Tutorial.FMX.pas, I also added conditional definitions:

  {$IFDEF MSWINDOWS}
  Winapi.Messages, Winapi.Windows,
  {$ENDIF}

4. In the IDE (Delphi 12):
   • Add Target Platform.
   • Open “Edit SDK”.
   • Go to Deployment → SDK Manager.
   • Add additional frameworks (see screenshot):

   $(SDKROOT)/System/Library/Frameworks - AVRouting  
   $(SDKROOT)/System/Library/PrivateFrameworks - AVFCapture
   $(SDKROOT)/System/Library/PrivateFrameworks - AVFCore

   Without this, compilation errors may occur, for example:
   [dccosxarm64 Error] E2597 ld: file not found: /System/Library/Frameworks/AVRouting.framework/Versions/A/AVRouting for architecture arm64
   [dccosxarm64 Error] E2597 ld: file not found: /System/Library/PrivateFrameworks/AVFCapture.framework/Versions/A/AVFCapture for architecture arm64
   [dccosxarm64 Error] E2597 ld: file not found: /System/Library/PrivateFrameworks/AVFCore.framework/Versions/A/AVFCore for architecture arm64

After these steps, everything worked successfully!

Your hypothesis worked. So you need to change the facade module GenAI.pas so that there are no accumulations like: TDeletion = GenAI.API.Deletion.TDeletion;

[MaxiDonkey]

Hello,

Thank you very much for your help, and especially for your persistence in finding this solution. Your tests made it possible to precisely identify the source of the issue.

The problem seems to be limited to the Apple ARM64 / iOS compilers, which do not handle a large accumulation of aliases in the GenAI.pas façade module very well. This behavior does not occur on the other platforms.

In the next DelphiGenAI update, I will take this specificity into account by using conditional compilation directives. The façade aliases will remain available by default in order to preserve the usual ease of use, but they will be automatically disabled for the affected targets, in particular through the compiler symbols:

DCCOSXARM64
DCCIOSARM64
DCCIOSSIMARM64

An override directive will also be provided, for example:

GENAI_FORCE_FACADE_ALIASES

to allow them to be manually re-enabled if needed.

Thank you again for your involvement, your patience, and the time you spent helping me isolate this issue.
