nrnivmodl compiling in Linux

Post by dzocchi »

I'm using ubuntu 2.6.38 and installed Neuron from the 32 bit deb file. When trying to compile mod files from another model, I get the following error:

/usr/bin/ld: cannot find -lncurses
collect2: ld returned 1 exit status
make: *** [libnrnmech.la] Error 1

I have been searching the forums but can't really find anything that helps much. Does anyone know what the problem could be?

Thanks!

Use your distribution's package manager to discover and install the package(s) that it needs for development or compilation of programs that use ncurses.

A comment: despite its general excellence in most other areas, Ubuntu has been the principal source of questions like this. For some reason or other, it doesn't offer users a simple option like "install everything I need to develop and compile programs written in C or C++."

In ubuntu it is convenient to use synaptic as a package manager. If you don't have it you can add it with a command like

Code: Select all

sudo apt-get install synaptic
When I used synaptic to discover what was missing (I typed ncurses in the synaptic search box when i received the ncurses missing message) I cured the problem by installing libncurses5-dev (in synaptic you can mark it for install and then apply).

Dear Tom, what if it is opensuse 13.1? I too get the same error on lncurses.

Hi usually when I get this problem in a new computer (ubuntu) I do the following:

Code: Select all

sudo apt-get install libncurses-dev

I needed this as well (Ubuntu 18.04 LTS):

Code: Select all

sudo apt-get install gcc
For some reason synaptic didn't pick this up.

If anyone gets here running NEURON with a miniconda installation, this is why it is happening and how to solve it:

Your default gcc may be on the miniconda path (/path/to/miniconda/bin), and it will look in your miniconda path for libraries, too (/path/to/miniconda/lib). apt-get won't install the ncurses libraries there, and miniconda's gcc won't look to where it does install. But you can do:

Code: Select all

conda install -c anaconda ncurses
And then run nrnivmodl as:

Code: Select all

nrnivmodl -loadflags "-L/path/to/miniconda/lib"
and then nrnivmodl will find the ncurses libraries and your mod files should compile.
