I am using C++ Builder and am getting the following errors:

[ILINK32 Error] Error: Unresolved external '__fastcall System::Internal::Strhlpr::UnicodeFree(System::UnicodeString&)' referenced from C:\PROGRAM FILES (X86)\EMBARCADERO\RAD STUDIO\9.0\LIB\WIN32\DEBUG\VCLE.LIB|ustring

[ILINK32 Error] Error: Unable to perform link

This is my code in main:

int _tmain(int argc, _TCHAR* argv[])
{

//TDateTime Mine("12/05/1990",TDateTime::TDateTimeFlag::Date);

TDateTime Mine("12/05/1990");

getch();
return 0;
}

And I have included ‘vcl.h’

What can I do to get this working?

    I don’t use Borland/Embarcadero tools nowadays, but I would guess you forgot to link to vcle.lib, as linker reports.

    It seems that TDateTime constructor uses Sysutils::StrToDateTime() which is implemented in vcle.lib.

    Add vcle.lib to linker settings, and see if it builds. Linker settings can be modified in Project Options > Linker
