Dear dac,
The same issue may arise in supercomputing centers, where some packages requires certain privileges to be installed by a simple yum/apt/pacman/etc command...
Indeed several versions of CentOS, which is the reference OS in HPC places, lack many of the requires packages...
Frequently, to overcome this issue I make local (/home/xxx) compilations of the requires libs (like bison, flex and cmake3)... and then I use "module" to set and load the env variables...
It's more work but it works...
Simplifying the AMBER installation would be very welcome...
All the best,
MatÃas

Asunto: [AMBER] Improving our options for pre-compiled AmberTools?

It's certainly true that our Installation instructions for Linux assume that
people can use standard package managers to install packages. For Ubuntu,
for example, we recommend this:
apt -y install tcsh make gcc gfortran flex bison patch \
bc xorg-dev libbz2-dev wget
But this indeed requires sudo privileges. I'm not anywhere near enough of a
conda guru to know if one could create a conda environment that would work
for compiling Amber.
So: I'm asking for advice from the list: how do people compile Amber in
places that don't have standard modules for the needed third-party stuff,
and for users that don't have sudo privileges? Possibilities:
a. detailed instructions on how to compile missing pieces from scratch?
For example, more things like the existing configure_mpich script,
which doesn't touch anything outside the Amber folder hierarchy?
b. Use singularity containers? Or something similar?
c. Ask people to install the AmberTools conda package, then provide
instructions for how to make just the things that are missing (mainly
MPI/GPU codes?
d. A better pre-compiled release that includes MPI/GPU functionality?
e. other ideas?
Don't let the "perfect" get in the way of the "better"! We can't solve all
problems. For example, Vaibhav's environment wouldn't even allow a
miniconda download. But if we could get closer to allowing folks to avoid
compilation, that would be a plus.
...thx...dac
