Thanks for the fix Peter.

If this is all known, what is the route for getting the source code fixed?

Kindly,


Ben

Subject: Re: [Disksim-users] FW: sqrt problem during make

I haven't used disksim in more than a year (so I am not an active user by any means), but your email prompted me to do some research about how I solved this.

In memsmodel/Makefile, just change:

mems_seektest: mems_seektest.o libmems_internals.a
         $(CC) -o $@ mems_seektest.o $(LDFLAGS) $(CFLAGS) -lmems_internals

to:

mems_seektest: mems_seektest.o libmems_internals.a
         $(CC) -o $@ mems_seektest.o $(CFLAGS) -lmems_internals $(LDFLAGS)

This should hopefully fix the sqrt problem. (I am not sure if that's all you need, but see if this helps.)

The duplicate case value is a result of a static assertion that checks to make sure that you are running on a 32-bit system. For 64-bit systems, you can get a patch from here:
http://scobyseo.blogspot.com/2009/12/disksim-40-ssd-extention-64bit-patch.html
The patch did not apply cleanly for me, so I had to apply it manually, and then it worked (plus you should feel free to ignore the ssdmodel part if you are not using the SSD extensions).

Best,
-Peter
