Fatal: Internal error 200305106

[paule32]

now, I have next Fatal Error 200305106

This is my console command, and output:

And the source code for system.pas, you can see there:

If I take your system.pas and try to compile I get a whole lot of other errors about string.

What is special about your system files?
(or am I missing something?)

He is trying to build his own system.pas but does not read any documentation about  how to implement the string types. He should at a minimum just implement just shortstring.

[rvk]

Ha. I see with an older FPC it does generate the error.

@paule32. Do note that your system.pas doesn't compile anymore with the latest FPC trunk version.
So your efforts might all go to waste if you upgrade your FPC in the future.

I advise you to at least upgrade it now so you don't get surprises later on in your development.

Yours:
Free Pascal Compiler version 3.3.1 [2024/02/20] for x86_64

Mine:
Free Pascal Compiler version 3.2.2 [2022/09/24] for x86_64

[Thaddy]

No, that is not related: system compiles just fine on trunk too (provided -Ur option is used)
Otherwise there would be no compiler (by sheer logic)... )

[rvk]

Yours:
Free Pascal Compiler version 3.3.1 [2024/02/20] for x86_64

Mine:
Free Pascal Compiler version 3.2.2 [2022/09/24] for x86_64

Yep. Yours is an older FPC 3.2.2 from 2022. Mine is latest trunk 3.3.1 compiled the day before yesterday.

Mine might give you better error message instead of those mysterious internal error.
(seeing that Thaddy mentioned implementing string types and the newer FPC gives errors about string type.)

[Thaddy]

Rik it is NOT related to tthe compiler itself. He is trying to build a modified compiler but lacks the knowledge to do so. Several people are trying to help him, but he is a stubborn Dane, who should be able to do that - writing a compiler - by birth. At least he understands wry humor, so nationality verified.

(Any system needs to be compiled before you have a compiler, bootstrapped by a last older version )

Haha, yes, I got that now

But he is also using an older version of FPC (3.2.2).
The newer trunk version FPC (3.3.1) gives more clearer messages about not being able to use the String alias in the system.pas unit.

So if he uses FPC trunk, at least the internal error is gone and the messages might be somewhat clearer (other than just "Internal error").
(see my error messages with trunk in message #2)

[Thaddy]

3.2.2 is the bootstrap compiler for trunk. So he also needs 3.2.2.

[Fibonacci]

Missing

procedure TObject.AfterConstruction;
procedure TObject.BeforeDestruction;

[Thaddy]

For his purpose he does not need those.
To come back to the compiler versioning: he can use overrideversioncheck=1, which is a make file setting. (usually NOT recommended, read as forbidden, but for this case allowed, but I guess he did not read the make file)

[rvk]

For his purpose he does not need those.

Maybe not needed for own purpose... but to get rid of the internal error, they are needed.

I used the 3.2.2 ppcrossx64.exe, added the BeforeDestruction and AfterDestruction and the internal error was gone.
Some extra errors about QObject.Create not defined etc could be solved easilly.

So... it seems the BeforeDestruction and AfterDestruction are needed.

Only as stubs, just like the stringtypes other than shortstring. After that he can clean up his own compiler code..... Good luck! Great Danes die young, btw.(the dog that is : avg 8-10 years)
IOW he needs to remove those from the compiler and that is not by any means easy.
(Working your way backwards and remove the parts you don't need)

If he or you encounter such issues, now you know what to do....

Thank you guys:
here is my effort result:
https://github.com/paule32/Qt_FPC/releases/tag/tag1

where did you get all this Information's - also the internal error's...
