Hi,

I have installed neuron 5.9.10 on a MacBook with Intel processor and get the error message below when trying to compile a mod file with mknrndll. The compiling of the same files works fine on a mac also running on OSX-10.4. Neither the i686 nor the powerpc versions work. Any suggestions?

Ta, Manfred

Creating powerpc directory for .o files.

This sounds like the same problem that afflicts people who find that their "workstation"
installation of Linux is unable to compile source code (see
Be sure your Linux can compile source code
https://www.neuron.yale.edu/phpBB2/viewtopic.php?t=586). The cause is that, by default,
Macs are delivered without the software development tools installed. The cure is to install
the software development tools; they are on one of the system disks that came with your
Mac. Might be called a "software development environment" or some other fancy schmancy
moniker.

Hi Ted,
You were right, after installing the Developer X-tools, the compiling of mod files is now working just fine. Better still, the simulation runs too.

May I ask one other question? I use the following command to plot voltage in soma and a dendritic compartment but it the y-axis is set at -1 to 1.

newPlotI()
{
graphItem.addvar("L1CR[0].soma.v(0.5)",2,1)
graphItem.addvar("L1CR[0].dend[65].v(0.5)",3,1)
}

However, if I use the plot command below for the soma only, then the y-axis is scaled automatically.
plotVoltage("Cell.soma.v( 0.5 ),2)

Is there a way to set the y-axis scaling with the first newPlotI procedure?

Thanks, Manfred

May I ask one other question?

Yes, but the question you asked belongs elsewhere. It's not OS X specific; instead, it really
pertains to NEURON's GUI and standard run system. There isn't a topic area devoted to
the standard run system, and I am not sure it is a good idea to start one, so I'll just open
a new topic under
Making and using models with NEURON / The GUI
then copy your question to it, and provide the answer there.

For the answer, see
