Building namd 2.12 from source an ARM64 architecture

Date: Wed Sep 27 2017 - 17:06:00 CDT

Hello namd mailing list,

I am trying to compile namd 2.12 on an ARM64 architecture but I am
unable to do show. I cannot even build charm++. At “./build charm++
multicore-linux64 –with-production” I get the following error (it is
clear that the g++ compiler does not work properly for me):

./gathertree ../../src/arch/`cat .gdir` .

Charm++ NOT BUILT. Either cd into multicore-linux64/tmp and try
to resolve the problems yourself, visit
for more information. Otherwise, email the developers at

I assume that from namd 2.10 and on ARM architecture is supported as
it is written in the release notes for that version. Has anyone any
experience building namd on ARM? Anyone encountered this error before?

Thank you for your time.
