Hi,

I installed NEURON 6.2 on Windows XP. Before doing anything else, I ran mknrndll and it worked succesfully, i.e. creating the nrnmech.dll file in the directory. However, after I uploaded .mod files (previously used succesfully on another computer) onto that directory and tried to rerun mknrndll, the following error message appeared:

gcc -DDLL_EXPORT -DPIC -I/cygdrive/c/nrn/src/scopmath -I/cygdrive/c/nrn/src/nrnoc -I/cygdrive/c/nrn/src/oc -I/cygdrive/c/nrn/lib -I/cygdrive/c/nrn/gccinc -I/cygdrive/c/nrn/gcc3inc -L/cygdrive/c/nrn/gcclib -c mod_func.c
mod_func.c: In function `modl_reg':
mod_func.c:46: error: parse error before "_reg"
mod_func.c:52: error: parse error before "_reg"
make: *** [mod_func.o] Error 1

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

I removed all .c, .o and .dll files from the directory, but that did not help.

Thank you in advance for any suggestions.

Suggest you uninstall 6.2 (use NEURON's own uninstaller, in the NEURON program group), then install the latest alpha version, which is available from

Hi Ted,

Thank you for your quick reply. Unfortunately, it seems like the .mod files that I am trying to use only work with NEURON versions 6.2 and older.

Best regards,

Jens

Had Cygwin or a different version of NEURON previously been installed on the PC where you are having trouble?
