The problem is that you're trying to compile the linux64 version, which
corresponds to the x86_64 architecture, not ARM.
I have little to no experience with ARM processors, but browsing through
the charm++ source files I saw that it has source code for the
"multicore-arm7" and "net-linux-arm7" architectures, which may suit your
needs. (you can find those in the "charm-6.7.1/src/arch" directory).
Replace "multicore-linux64" with one of those. What you can also do is
build charm++ interactively. If you simply run " ./build charm++ "
without any other arguments, a series of prompts will appear, allowing
you to select your compilers, architecture etc, each from a list of
available choices. If your system architecture is supported, you will
eventually build it.
Similarly, before you build namd itself, check the
"NAMD_2.12_Source/arch/" directory to see which architecture suits you
best (I saw a number of ARM related ones) and replace "Linux_x86_64-g++"
from the compilation guide with whichever is compatible with your system.
Hope I helped,
