I'm trying to revive an old project in C++Builder 11.3 (initially written in C++Builder 6). I'm using the 'classic' Borland compiler, which solves the wchar_t problem. But I'm getting this error:
[ilink32 Error] Error: Unresolved external 'std::char_traits<char>::assign(char *, unsigned int, char)' referenced from (...)\CRYPTLIB_BDS.LIB|integer
I found this post, to which one of the answers is to enable "Link with Dynamic RTL". I don't want to do that, I need to link it statically.
Another post suggests setting the -fno-inline-functions flag in the compiler, which didn't work either.
I tried to write the definition of the function, but then I got this error:
[bcc32 Error] File1.cpp(5): E2171 Body has already been defined for function 'char_traits<char>::assign(char *,unsigned int,char)'
Does anyone have any idea why this problem occurs, and hopefully what to do to get the project to compile and link properly?
The main problem is that the linker doesn't seem to find the definition of the std::char_traits<char>::assign(char *, unsigned int, char) function, but when I create the other body - the error shows up.
The problem seem to be the system memory architecture. When I recompiled the CRYPTLIB_BDS.LIB lib 64-bit configuration on bcc32 compiler the project started working. Also what I found is that every higher version of RAD Studio than 10 fails.
