Why the problem is happening

These _s functions come from a C standard addition termed as "Annex K", which introduces bound checking interfaces for common standard library functions, which are subfixed with _s (as in safe, secure).

However, Annex K is weird, Windows implemented it, but botched the API, whereas glibc (gcc's standard library) did not even bother, hence your GCC compiler cannot find those functions, they do not exist!

Possible Solution

In order for the application to be portable on compilers other than MSVC, the _s functions could be substituted with either:

1. Proper, modern C++ alternatives (might prove to be slower)
2. Their non _s alternative with a macro/preprocessor directive (some level of bounds checking would still be provided on GCC thanks to compiler hardening flags)
3. A more widely accepted but still safer alternative, e.g.: strncat instead of strcat, snprintf instead of sprintf, etc...

Already tried to port it on my own but there is a specific winapi function thati can't use or recreate even via wine libs

Do you have a line number for the func?
