Hello,

I have downloaded neuron, and have the associated modules etc. but I cant seem to get it to open up when I launch nrngui. I have macOS Mojave Version 10.14 Beta.

Did you build from sources or use the pkg file distribution. If the latter, have you intalled the software from xquartz.org and the command
line tools. If the latter what configure line did you use. What python do you have installed. Does the following work?
Start a terminal window and in the terminal window type
/Applications/NEURON-7.6/nrn/x86_64/bin/nrniv -nopython

Sounds like I may have to install another virtualbox guest on my mac 10.13

Im uninstalling it and downloading it again. Also, I am downloading command line tools but it is still not working. I have python 3.7 downloaded.

I tried to install the mojave beta on a virtual box clone of high sierra. Gets what seems to be close to success but will not boot. Hangs at the
boot message
/dev/disk0s2 on / (hfs, local, journaled)

Ok, so are some steps i can take to fix the installation process.

I'd like to know the result of the terminal experiment I mentioned earlier. That will generate several further questions.

This is what I got when I entered that line in terminal.

Akashs-MacBook-Air:~ akashchandra$

one last diagnostic test using a terminal window. What is the output of
otool -L /Applications/NEURON-7.6/nrn/x86_64/bin/nrniv
The executable expects to get those variables from /usr/lib/libedit.3.dylib
Also what is the result of
ls -l /usr/lib/libedit*
ls -l /usr/lib/libreadline*

The output for otool -L /Applications/NEURON-7.6/nrn/x86_64/bin/nrniv is,
/Applications/NEURON-7.6/nrn/x86_64/bin/nrniv:
/Applications/NEURON-7.6/nrn/x86_64/lib/libnrnoc.0.dylib (compatibility version 1.0.0, current version 1.0.0)
/Applications/NEURON-7.6/nrn/x86_64/lib/libnrniv.0.dylib (compatibility version 1.0.0, current version 1.0.0)

and for the ls -l /usr/lib/libedit* command it is

lrwxr-xr-x 1 root wheel 15 Aug 20 20:35 /usr/lib/libedit.2.dylib -> libedit.3.dylib
lrwxr-xr-x 1 root wheel 15 Aug 20 20:35 /usr/lib/libedit.3.0.dylib -> libedit.3.dylib
-rwxr-xr-x 1 root wheel 308224 Aug 17 06:01 /usr/lib/libedit.3.dylib
lrwxr-xr-x 1 root wheel 15 Aug 20 20:35 /usr/lib/libedit.dylib -> libedit.3.dylib

ls -l /usr/lib/libreadline* output :

lrwxr-xr-x 1 root wheel 15 Aug 20 20:35 /usr/lib/libreadline.dylib -> libedit.3.dylib

The otool output for nrniv is seriously perplexing. Mine is much lengthier with... and you can see I'm getting libedit to resolve all the readline variables . ie.
lrwxr-xr-x 1 root wheel 15 Mar 28 05:53 /usr/lib/libreadline.dylib -> libedit.3.dylib

It seems like your problem is that dynamic libraries that exist in their normal places are not being requested, or loaded. Or perhaps I'm barking up
the wrong tree. I don't have any ideas
off hand as to why that would occur or how to deal with it. I will need to install Mojave, and experiment with that.

ok thank you. Were you able to play around with it.

Thanks

I've been unable to successfully install mojave as a virtual box guest. It will be away for two weeks and can get back to the problem at that time.

I have the same problem after installing last week's official release of 10.14 Mojave.

With the latest Mojave command line tools and X11 installed, and a fresh install of NEURON 7.6, attempting to open nrngui leads to the following:

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. If you install from a package file, let me know and I can upload to the alpha folder.

I'm installing from the latest package installer. Thanks.
