GCC in Stretch

[Tichun]

Why do we have both the GCC 4.9 and the GCC 6?
Correct me if I'm wrong but the older one seems as if it was the default.
Which one should I rather choose when compiling things myself?

For me "gcc -v" returned 6.3 so I think it is the default.
Taking a look, we have various versions:-

Code: Select all

pi@raspberrypi:~ $ dpkg -l | grep gcc
ii  gcc                             4:6.3.0-4                    armhf        GNU C compiler

Strongly suggest using the latest version of the compiler, especially on ARM.

I immediately replace it with gcc 7.2 anyway!
