I'm glad I could be of any help. As for OpenGL, I haven't heard of ARM
platform providing full OpenGL (not ES); apart form that, I lack any
expertise here, sorry.
You will need to rely on John Stone and other VMD/NAMD developers who
actually compiled both programs on ARM. I don't even know if this is
possible with OpenGL ES - they might refer to text-only version of VMD.
The last question of John was what compiler/toolchain are you using.
Since its Debian, the most likely bet is gcc, the second one being
clang. Try to see where these links go on your system:
ls -l /etc/alternatives/cc /etc/alternatives/c++
you will see if the default compiler is gcc/g++ or clang. Then command:
gcc --version
or clang --version
and provide this info to answer the John's question from Jan 23rd. To
get most help, a good idea will be to provide any other relevant info,
like the architecture your Debian system is configured for, versions of
dependencies you have installed (like tcl-dev/tk-dev), the error the
compilation ends with etc. The architecture is reported as the third
word from apt list command, e.g. on mine laptop:
apt list gcc
shows "gcc/xenial,now 4:5.3.1-1ubuntu1 amd64 [installed]" where "amd64"
is the architecture; on Pinebook it most likely is arm64 but better to
make certain. In the same way you may check the versions of anything you
installed from the Debian packages.
Getting VMD to work on OpenGL ES platform may not be easy; its not only
VMD which would need to support it, but also the FLTK library which IIRC
provides the OpenGL window (and the GUI, of course). So I would start
small and try to compile without OpenGL and FLTK to sort out a smaller
set of problems first. OTOH, such binary will only be useful for
scripting and not for interactive work :(.
