# #############################################################################
# This image provides platform setup and GCC required for all platforms.
#
# 64-bit centos7 provides devtools-10 for arm64, devtools-11 for amd64 and 
# gcc 4.8 for 32-bit archs. This image builds modern gcc from sources. 
# It guarantees that we would use the same GCC version for all builds, 
# and we would be able to upgrade GCC to a newer version if required.
