Dear all,
I'm trying to install NEURON on the latest ubuntu (11.04) but I run into trouble.

This is the error:

make[3]: Leaving directory `/home/mattions/Work/progs/neuron/neuron-hg/nrn/src/oc'
Making all in nrnoc
make[3]: Entering directory `/home/mattions/Work/progs/neuron/neuron-hg/nrn/src/nrnoc'

Can't create C file: ./hh.c at line 0 in file ./hh.mod

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/mattions/Work/progs/neuron/neuron-hg/nrn'
make: *** [all] Error 2

Any idea why this is happening?

I just running the classic ./configure make routine.

Actually I found out that the problem was a folder with root permission. Deleting the repo and clining again fixed the compilation.

Installing the python instead was a bit more tricky.

I have no idea why, but using the classic ./configure (no prefix) the python module is installed in two different location with two different folder, with different modules inside.

Code: Select all

/usr/local/nrn/share/nrn/lib/python
/usr/local/lib/python2.7/dist-packages

Remarkably, the hoc library is present only in one directory, and the rdxml module in the other one. Pickiing up and copying all the content in one and exporting that directory seems ok to solve the problem.

An unrelated problem with install on Natty: slow processing of input lines due to some kind of readline incompatibility.

This manifested in an xterm by extremely slow cut and paste of commands into neuron with either the hoc or python prompt (slow line parsing)

The solution was to use the NEURON native readline instead of the system readline: configure with '--with-readline=no'
