Internal Error: URW1147

[Uefi1]

Hello in the new version 2.2 when trying to compile on Delphi XE2 error F2084 Internal Error: URW1147 this error occurs in the file mormot.core.json

[synopse]

Did you try with the latest trunk revision?

[Uefi1]

Oh, sorry, not version 2.2, but the latest one, if downloaded via github>code>download

This is a compiler bug, specific to XE2.
I don't have this compiler installed, so I can't fix it. It work on my side with Delphi 2010 and XE4.

You know, I once encountered such a bug, the problem was in the inline directive

[synopse]

Yes, I know but without a compiler, I don't know how to circumvent it.

You could try to disable some "inline;" in the source code, perhaps not even in mormot.core.json but in mormot.core.rtti.
Try first to add {$undef HASSAFEINLINE} in the beginning of the unit.

Damn, there’s something deeper there, I tried as you said, but it didn’t work ( I can’t even track this error with a debugger (

Hi, it looks like the latest release that compiled without this error is b546540

[synopse]

I don't get how 30b619c2813a3 (the very next commit) could be invalid for Delphi XE2. It is 64-bit specific code, which is not used by XE2 at all.

[Uefi1]

Or maybe the binaries do not fit the latest library and that’s why the error occurs?

[synopse]

URW errors are a pure Delphi compiler bugs.
It is just a bug of the compiler which is not able to compile the code.
Nothing to do with static linking of external librairies.

[Uefi1]

Can you somehow fix this ?

[synopse]

Without the compiler itself, I can't.

[Uefi1]

Try downloading Delphi XE2 ?

[Uefi1]

Hello, I actually found the latest version that still compiles on Delphi XE2, this one:
0f65917

[synopse]

What if you change
procedure AddU(Value: PtrUInt);
into
procedure AddU(Value: cardinal);
in mormot.core.text ?

[Uefi1]

No, unfortunately it didn’t help =(

[synopse]

I was able to install a Delphi XE2 compiler.

First of all, I see no problem with Win32 target.
Only on Win64 I got this F2084 Internal Error: URW1147.
I will try to investigate. Delphi is just buggy as hell.

It sounds linked to generics: https://stackoverflow.com/questions/9429484/what-should-i-do-about-an-internal-error-when-i-declare-a-generic-array-of-t
But even if I disable generics... it does not compile...

@Uefi1
Did you install all available updates on your Delphi XE2? That is UP4+HF1?

Please try with this above commit.

[Uefi1]

Please try with this above commit.

Yes, this commit compiles successfully, it worked, thank you very much =)

[Uefi1]

Hurray, the latest version now compiles if you download it from github>Code>download zip thanks for the correction !
