neuron 6.2 on XP, mknrndll does not function

[btorb]

Dear, In order to use the python interface with neuron i just switched from neuron 5.9 to neuron 6.2. On my windows computer, this resulted in the fact that i'm unable to compile mod files with mknrndll. (On another computer with linux it works fine).

After selecting the directory in which the mod files are located, both nrniv and the complete shell (rxvt?) crash without leaving a trace. To resolve the error, i opened the rxvt terminal and filed the following command manually:

sh /cygdrive/c/nrn62/lib/mknrndll.sh /cygdrive/c/nrn62

(the command is given in the directory containing the mod files).

The following is the output:

There was an error in the process of creating nrnmech.dll
Press Return key to exit

Probably I'm doing something very stupid and i would appreciate if somebody could point out what exactly it is that i do wrong.

Kind regards and thanks in advance, Ben

remove all the *.c, *.o, and *.dll files from your directory and try again.
