This problem may sound simple to experienced users but i am very new to this environment. Downloaded MAC version of NEURON ; mknrndll will not function. Xcode in use error message when trying to use downloaded simulation model is *.mod *.mod make: *** No rule to make target `mod_func.c.lo', needed by `libnrnmech.la'. Stop. Similar message when trying to start nrn by dragging to mknrndll.app Any suggestions greatly appreciated. JM

Under OS X the usage of mknrndll consists of the following:
Drag a folder containing mod files or a set of mod files onto the icon. Press return to close this window.

Is that what you did? If not, try it and see if it succeeds.

Tried that with no luck then went to X11 version. Passed initial hurdle only to find a new one. Full error message follows:

Path to library not found or the code is not being read properly, not sure. Any suggestions. Many thanks
