[ilink32 Error] Error: Unresolved external '___unnamed_5'

[Navadvipa Chandra das 0]

Hello, All!
There was a fully functional library for C++Builder 6. I started translating it to C++Builder 10.4.2. I divided it into two packages - one for FMX, the other for VCL. The VCL_NizhnyayaNavadvipa package is successfully compiled, but not successfully linked. And I can't figure out where the error is, because the linker gives the generated names - '___unnamed_4' and '___unnamed_5' !

here's what he writes
[ilink32 Error] Error: Unresolved external '___unnamed_4' referenced from C:\C\NIZHNYAYANAVADVIPA\WIN32\DEBUG\CWDTREE.OBJ
[ilink32 Error] Error: Unresolved external '___unnamed_5' referenced from C:\C\NIZHNYAYANAVADVIPA\WIN32\DEBUG\CWDTREE.OBJ
[ilink32 Error] Error: Unable to perform link

Where is the problem? How to find it? Can anyone help?
Thank You!
With best regards, Navadvipa Chandra das.

Hello, All!

 

Problem create this row:

 

        TCWNodeAdmin *na = dynamic_cast< TCWNodeAdmin* >( AComponent );

Thank You!

Hello, All!

But an even bigger miracle is that when I moved the entire

void __fastcall TCWDBTreeView::Notification(TComponent *AComponent, TOperation Operation)

method entirely to the end of the file cwdtree.cpp , then the linking problem has disappeared! Hurray!
It turns out that the order of the methods in the cpp file matters!

Thank You!
