[Disksim-users] sqrt problem during make

[Payne, Benjamin]

Hello,

>From reading the list archives, I see the problem with sqrt being undefined during installation isn't new:
https://sos.ece.cmu.edu/pipermail/disksim-users/2011-December/000699.html
http://cboard.cprogramming.com/c-programming/144182-gcc-compile-problem-link.html

The details are below, but my question is on fixing this. Did I make a mistake during installation, or is this normal? If the error is normal, how can it be fixed?

On a fresh installation of Ubuntu 12.04 64bit, I ran the following commands to get started with disksim:

sudo apt-get install flex bison
wget http://www.pdl.cmu.edu/PDL-FTP/DriveChar/disksim-4.0.tar.gz
tar xzf disksim-4.0.tar.gz
cd disksim-4.0
make

The output from "make" is

make[1]: *** [mems_seektest] Error 1
make[1]: Leaving directory `/home/bpayne/disksim-4.0/memsmodel'

However, by running the following

cd memsmodel
gcc -Wall -Wno-unused -MD -o mems_seektest mems_seektest.o -lm -L. -g -DASSERTS  -I../src// -I../ -I../src//src -lmems_internals -lm
cd ..

and then trying make again, I get new output:
