I have a C++11 project, and I added some strcpy_s method calls. This works on windows, but when compiling on gcc, there is an error stating that strcpy_s symbol is not found.

I did add the line

#define __STDC_WANT_LIB_EXT1__ 1

to the code, to no avail.

GCC (or rather, glibc) does not support strcpy_s() and friends. For some ideas on where you can find a library which does support them, see here: Are there any free implementations of strcpy_s and/or TR24731-1?
