Re: compiling issues on Mac

It is not hard to build from sources on the mac, but be aware that there is an installation pkg available that does not require the "brew" developer tool hints alluded to below and also attempts to install xquartz and command line tools if they are not already installed. See: https://neuron.yale.edu...

Re: Compile Neuron

Informaiton about the build environment used to construct a neuron setup.exe distribution is scattered in the nrn/mingw_files folder. Given a valid build environment, I construct a setup.exe using sh howto 37 36 27 Setting up a build environment is explained in the msys2 file. mingwnotes has some ve...

Re: Conflict between CVode.maxstep, NetCon instances, and extracellular

That is an oversight. cvode wraps ida and the former is persistent while the latter is destroyed/created whenever the model topology, or if the model requires a differential algebraic solver, changes. Extacellular requires ida. I forgot to make all the ida calls to reflect the existing cvode style f...

Re: Installation problem Neuron

Ok. so there is no problem with command line tools and readline. I think the next diagnostic test is to install a distributed pkg file for NEURON and see if that works with your python3.7. Please try https://neuron.yale.edu/ftp/neuron/versions/alpha/nrn-7.6.2-18-gcfe5f00.x86_64-osx-py-37-36-27.pkg J...

Re: Installation problem Neuron

-with-readline=no
I assume that is just a typo and you used --with-readline=no
Anyway, have you updated the command line tools. And perhaps you can reinstall python3.7.
I build the distribution with python3.7 and do not see this issue.

Re: Installation problem Neuron

The icon launch mechanism is fixed with nrn-7.6.2-18-gcfe5f00.x86_64-osx-py-37-36-27.pkg in the alpha download folder. So all functionality on high sierra 10.13 exists with Mojave 10.14. Note that the first launch of an icon may pop up a system request for your permission. Mojave has increased the s...

Re: Installation problem Neuron

Please try
nrn-7.6.2-15-gbdf78f2+.x86_64-osx-py-37-36-27.pkg
from
https://neuron.yale.edu/ftp/neuron/versions/alpha/

The icons are non-functional in this version due to the missing launcher program. So you will have to use a terminal window for
nrnivmodl
nrngui
etc.

Re: Installation problem Neuron

If installing from sources, use the configure option --with-readline=no Also a library I used for the icon launch mechanism has been deprecated out of existence. That can be temporarily worked around by modifying nrn/src/mac/Makefile.am to comment out a single line. ie. diff --git a/src/mac/Makefile...

Well, good. However I am truly astonished by this requirement. What specific anaconda version is this?

Re: Problems with 'make' when trying to install NEURON with MPI+Python (Ubuntu 16.04)

Ok. So the issue is related to anaconda python. turns out there are a number of google error references for vtable for std::__cxx11:: basic_stringbuf and I notice on that may be relevant. As it turns out,e GCC 5 introduced new implementations of std::string and std::list. You can try the workaround ...

Re: Problems with 'make' when trying to install NEURON with MPI+Python (Ubuntu 16.04)

I'm traveling and have a Mac powerbook with a virtual box guest ubuntu 16.4 with gcc 5.4.0. Are you using a tar.gz or the GitHub repository files? I would try the latter git clone http://github.com/neuronsimulator/nrn cd nrn sh build.sh ./configure ... etc. It may be worth while to focus on a stripp...

Shall I try installing NEURON again? I don't see much chance of success unless something substantive changes on your system.

Re: Problems with 'make' when trying to install NEURON with MPI+Python (Ubuntu 16.04)

The openmpi is working. But I missed the fact in your earlier message that the problem has nothing to do with mpi as linking fails even in the absence of --with-paranrn. That makes me wonder if you have an incomplete g++ development environment or one that has inconsistent libraries. The build envir...
