# AWS Lambda based build
#
# NOTE - this is a bit a a hack as Centos7 comes with boost version 1.53, and several
# of the required libraries require this version, but recent RDKit builds (since the 
# switch to modern C++) require boost 1.56 or later.
# The solution is to build boost binaries for 1.56 so that RDKit can be built against
# those and to copy those binaries into the destination image, and to use the --nodeps
# option when rpm installing the RDKit RPMs.
# The resulting image has both versions of boost in /usr/lib64 and RDKit seems to be
# quite happy with this.
#
# Credit to Paolo Tosco for helping to work out a strategy for this.
