# Raspberry Pi is ARMv6+VFP2, Debian armhf is ARMv7+VFP3
|
|
# Since this Dockerfile is targeting linux-arm from Raspberry Pi onward,
|
|
# we're sticking with it's custom built cross-compiler with hardfp support.
|
|
# We could use Debian's armel, but we'd have softfp and loose a good deal
|
|
# of performance.
|
|
# See: https://wiki.debian.org/RaspberryPi
|
|
# We are also using the 4.7 version of the toolchain, so that glibc=2.13
|
|
|
|
# Instead of cloning the whole repo (>1GB at the of writing this), we want to do a so-called "sparse checkout" with "shallow cloning":
