Neurondemo floating point exception in x86_64 debian

Post by bruxonildo »

Hi all,

I installed neuron in a debian 64bit machine. When trying to run the neuron demo I get the following:

loading membrane mechanisms from /usr/local/apps/nrn/share/nrn/demo/release/x86_64/.libs/
/usr/local/apps/nrn/share/nrn/demo/neuron: line 12: 21122 Floating point exception"${NRNIV}" -dll "/usr/local/apps/nrn/share/nrn/demo/release/x86_64/.libs/" "$@"

Has anybody encounter this? Does anybody know how to solve this?

nrniv runs fine but I am guessing that I could encounter the same problem with one of the membrane mechs.

Cheers, M

Remove the old neurondemo code with
rm -r -f /usr/local/apps/nrn/share/nrn/demo/release/x86_64
rm -f /usr/local/apps/nrn/share/nrn/demo/neuron
and then launch neurondemo.
I'm wondering if you happened to have an old installation at that location and are using the previous neurondemo shared object.

Hi Michael,

Thank you for the suggestion. I did have an older version of neuron installed. I followed the instructions and now neurondemo works.

Greetings, M
