Compilation fails on supposedly missing c headers

[mbezaire]

Running NEURON 8.2 in Windows 11, I run into the following issue when trying to compile the *.mod files in this model:

In file included from misc.c:193:
misc.h:7:10: fatal error: sys/time.h: No such file or directory
    7 | #include <sys/time.h>
      |          ^~~~~~~~~~~~
compilation terminated.
make: *** [/cygdrive/c/nrn/bin//../lib/mknrndll.mak:26: misc.o] Error 1

There was an error in the process of creating nrnmech.dll

This occurs whether I use mknrndll at a prompt or NEURON's mknrndll GUI tool. It occurs for multiple Windows users, at least some of whom have verified the presence of the "missing" header files in their usual places.

Any work arounds or ideas of what I should do next? Thanks

Generally speaking, NEURON models that don't use VERBATIM blocks should work the same across all platforms. For the ones that do, however, the authors could write code that doesn't support certain platforms and I think that's what happened here. My impression from Googling is that all platforms have a time.h, but not everybody has a sys/time.h.

That said, I didn't see anything that I recognized as coming from sys/time.h, so maybe it's not defining anything that's used in the rest of the program...

I haven't tried this, but did you try removing the offending include line from misc.h?

(My guess, again not having tried, is that even if it did define something used, you could probably get rid of anything in the code that cares about real time at all.)

One thing that would definitely work would be to run NEURON through WSL but I acknowledge that adds a bit of complexity, and I'd rather see this model fixed to work on Windows.

Thanks, I tried commenting out the #include <sys/time.h> that appears in misc.h and misc.mod (VERBATIM).

Now when I attempt to compile I see:

Hello, I am having these exact same two issues. Was any resolution met on this?

I will need to check this weekend, but for misc.mod, it may have been possible to just delete the file.

And everything will still function okay if I delete misc.mod?

Hi, I just wanted to see if there was an update on this?
