Hello, on this note, I'm having issues configuring and installing the
mpi enabled mdrun. (see below). I keep getting a strange error:<br>
<b>checking size of int... configure: error: cannot compute sizeof
(int), 77 <br>
</b>I've pasted the output below, and I've attached the config.log for
reference. I'm really not sure what's going on here, so if anybody
could help, would greatly appreciate it. <br>
<br>
Regards, <br>
<br>
