I installed neuron 6.1 on a ubuntu system (AMD64) from the binary rpm-package via alien.
The ubuntu system is part of a cluster, so it has no graphical interface. As far as I can see everything works fine, but compiling nmodl-files I run into a problem.
The compiling process stops as the linker complains that he cannot find X11.
Reading in the forum I saw that it is possible to avoid the gui at all building neuron from source code. https://www.neuron.yale.edu/phpBB2/viewtopic.php?t=1171/usr/bin/ld: cannot find -lX11
collect2: ld returned 1 exit status
make: *** [libnrnmech.la] Fehler 1
Honestly I hope that there is really simple solution like an option for nrnivmodl, so that I don't have to bother me with compiling from scratch.
