c++ - Reference error when attempting to build/link project with mingw-w64

Question

I am trying to build my program and have been getting errors that I don't know how to resolve.

The errors are undefined reference to '__security_init_cookie' and undefined reference to '__mingw_init_ehandler'. I suspect it's something to do with linking but I am unsure how to solve this, I found no real resolutions on google.

My compilation args are below with the relevant error:

Compilation:

Any help is very much appreciated; I've been at this for days and I just want to move on to coding!

Answer 1

Similar problems has happened to me before. When the following message shows, the problem usually would be the static library is not found

undefined reference to ....

My suggestion would be why not move your static libraries ".a" into the folder

/x86_64-w64-mingw32/lib/
