Unable to use latest LGenerics with latest FPC trunk

ikelaiah commented 4 months ago

Hi @avk959,

Thanks for the fine library for FPC. I am runnning into issues when compiling with FPC trunk and using lghashmap. I get the following error.

Can you help? Many thanks.

Yeah, I'm aware of that. FPC changed their approach to member visibility in generics not too long ago. I'll have to look into it as soon as I have enough time.

ikelaiah commented 4 months ago

Thanks @avk959 .

avk959 commented 4 months ago

Seems to be fixed? At least yesterday's FPC-3.3.1-15663-ga888a141a2-dirty(x86_64-linux) can now compile the current version of LGenerics.

ikelaiah commented 4 months ago

Thanks @avk959 , I'll test.

ikelaiah commented 4 months ago

Hi @avk959 ,

Since you compiled it with FPC-3.3.1-15663-ga888a141a2-dirty(x86_64-linux), most likely my setup is not right. Thanks for checking, and I'm closing this issue now.

It's impossible to give any advice without seeing the source code.

ikelaiah commented 4 months ago

Hi @avk959

I'm reopening this again, providing my code (which I should have provided earlier). I'm still stuck, hoping you can help.

program GHashmapLPDemo;

{$mode objfpc}{$H+}

uses
  {$IFDEF UNIX}
  cmem, cthreads,
  {$ENDIF}
  Classes,
  lgHashMap,
  SysUtils;

type
  TDictionary = specialize TGHashMapLP<shortstring, int64>;

var
  dict: TDictionary;
  s:shortstring;

begin

  dict := TDictionary.Create;
  try
    dict.Add('One', 1);
    dict.Add('Two', 2);
    dict.Add('Three', 3);
    dict.Add('Four', 4);

    WriteLn('Printing key-value...');

    for s in dict.Keys do
    begin
      WriteLn('Key: ', s, ' Value: ', dict[s]);
    end;

  finally
    dict.Free;
  end;

  WriteLn('Press enter to exit');
  ReadLn;

end.

And I get this error message when I compile using F9 in Lazarus IDE.

Hey Iwan(@ikelaiah),

Could you provide the compiler and Lazarus version please? Many thanks in advance!! If you did already, I'm really sorry for repeating the question!! :people_hugging: :heart:

Cheers, Gus

ikelaiah commented 4 months ago

@gcarreno , sure!

Lazarus 3.99 (rev main_3_99-1970-g06f123d8dd) FPC 3.3.1 x86_64-win64-win32/win64 Free Pascal Compiler version 3.3.1-15679-g5284948087

Thanks.

Looks like the OpenStrings compiler switch is now enabled by default in DELPHI mode. Just try replace line 22 in the lgUtils unit with {$MODE DELPHI}{$P-}.

ikelaiah commented 4 months ago

Thanks for the suggestion. Here's what I did.

Replaced line 22 in the lgUtils unit with {$MODE DELPHI}{$P-}
Reloaded and recompiled the lgenerics.lpk
Cleaned up project and recompiled

It works in Debug mode, with correct output.

$ ./GHashmapLPDemo.exe
Printing key-value...
Key: Two Value: 2
Key: Four Value: 4
Key: Three Value: 3
Key: One Value: 1
Press enter to exit

Heap dump by heaptrc unit of "C:\Users\iwank\Documents\fp-projects\free-pascal-snippets\LGenerics\GHashmapLP\GHashmapLPDemo.exe"

When I run in Release mode, it give me the following.

$ ./GHashmapLPDemo.exe

Progress! We are getting somewhere.

Additional info.

When I compile the project under Release mode, I get the2 warnings. But no warning in the Debug mode.

Warning: Object file "GHashmapLPDemo.o" contains 32 bit absolute relocation to symbol ".data.n_TC_$GHASHMAPLPDEMO_$$__static_tgopenaddressing$4$crc0769d515_crc7da784b1_MAX_CAPACITY".

My results for your example are:

FPC 3.3.1-15705-gac8fefbc2b-dirty-x86_64-linux,
optimization level -O3: OK;
FPC 3.3.1-15682-g59e307ec2e-x86_64-win64,
optimization level -O3: Access violation; optimization level -O1: OK;

To me all this along with the linker message looks like a compiler problem, what about you?

ikelaiah commented 4 months ago

I see. It does look like a compiler's problem.
