Hi,
I'd like to report a bug when compiling x64 in rad studio 11.3 and 12. x32 compiles without issue. I have also included an example test project within the zip.
Steps to reproduce:
1) Create new VCL application
2) Add Windows 64-bit platform
3) Turn off Link with Runtime packages
4) Drop an RVStyle and RichViewEdit control onto the form
5) Compile in 64 bit mode, and get an error: [ilink64 Error] Error: Unresolved external 'System::Rtlconsts::_SListIndexErrorExt' referenced from C:\PROGRAM FILES (X86)\EMBARCADERO\STUDIO\22.0\LIB\WIN64\RELEASE\DBRTL.A|Data.DB.o (see screen shot in zip file)
When contacting Embarcadero they suggested the below for TRichView:
"TRichview could fix this issue, by moving the databinding registration code into their design package. (I did this in my minimal test case and it worked)"

Re: Fatal error compiling x64 in RAD Studio 11.3/12
I need some time to understand why it happens.
I cannot reproduce the linker problem. On my RAD Studio 10.3 (about box displays: Embarcadero® RAD Studio 11 Version 28.0.47991.2819), the application is compiled successfully. But it shows an exception in livebinding registration code when the application starts.
As I understand the suggestion, it is about moving the call of RegisterObservableMember to design-time code.
I tried. But after that, livebinding stopped working (i tested "DB Demos.FireDAC_IB\4 LiveBindings").
So I need more time to understand how to fix this problem.

As I said, I cannot reproduce the linker problem.
I can see only a crash on start. The problem is definitely in a wrong unit initialization order for C++Builder 64-bit.
I found a workaround.
In RichView.pas and RVEdit.pas,
1) remove
from implementation's "uses"
2) add
in interface's "uses"
After that, rebuild TRichView packages (run "Install TRichView VCL in Delphi IDE" shortcut in Windows Start Menu)

Well, it appeared that this change crashes the command-line compiler of Delphi 12, it reports "RichViewActionsD12.dpk(153) Fatal: F2084 Internal Error: LI693". Older compilers are OK.
The solution is changing "uses" as I said above, but without moving from implementation to interface section.

Thank you for your quick support! I will give your suggestion a try.

The fix is included in TRichView 22.1.1 (currently available only for registered users)
