Tell runtime/cgo to not thread warnings as errors

Occasionally, you want to debug (with delve) your project, but when you attempt to do so, you are greeted with the following error:

 #  warning _FORTIFY_SOURCE requires compiling with optimization (-O)
    ^~~~~~~
cc1: all warnings being treated as errors

To resolve this, just export CGO_CFLAGS with the value "-O2 -g -Wno-error".

Is there a difference between slices and arrays? Well, if there is any, it is a difference of relations. slice depends on array, when you declare a slice in Go you get an underlying array associated with your slice, if you have several slices of the same type they may even share storage with the underlying array.

How do you create a slice?

You can use the same facilities for declaring arrays in Go, with the optional argument for "capacity" provided:

make([]int, 50, 100)

This is the same as creating an array and slicing it:

new([100]int)[0:50]
