"Resource unavailable" error messages

After an upgrade to SuSE 10.3 I was forced to recompile NEURON-6.0 and am now getting a ton of error messages when I run nrngui (this persisted when I compiled newer versions as well):

NEURON -- Release 6.1.1 (1894) 2007-11-24

Any ideas what I am doing wrong?

This could be just prevented by editing the nrn/src/oc/math.c in the region near the end of the file in the hoc_errno_check function. And I might end up doing that in the distributed sources. However, I would prefer diagnosing the location a bit more precisely. If you don't mind working with me on that, then start over by installing the latest tar.gz file from http://www.neuron.yale.edu/ftp/neuron/versions/alpha/
and I will iteratively supply one or two modified files with printf statements that will help figure out where the errno is being set. Let me know by email when and if you are ready to begin

Hello,

Sorry to reactivate this old topic...

I have compiled NEURON 6.1 under fedora 8 and the same problem occur. It's sometime interfering (for instance with printf statements).

Is there a solution?

Thanks in advance.
Mathieu.

The standard distribution now points to
NEURON -- Release 6.1.2 (1927) 2007-12-30
so if you re-install after downloading as before the problem should go away. See
http://www.neuron.yale.edu/cgi-bin/trac ... geset/1927
for a list of Release 6.1.2 changes. The changeset that got rid of useless "Try again" error messages was 1920.

It works perfectly with version 6.1.2!

Thanks,
Mathieu
