<div>Hi all, I just fixed the problem.<br>
</div>
<div><br>
</div>
<div>Use the following code to compile:<br>
</div>
<div><br>
</div>
<div>gfortran hs071.f90 -o hs071.out -L /usr/local/lib -lipopt -g -Wall -fcheck=all<br>
</div>
<div><br>
</div>
<div>But notice that if your library of IPOPT is 64-bit, need to change the code from<br>
</div>
<div><br>
</div>
<div>integer IPROBLEM<br>
</div>
<div>integer IPCREATE<br>
</div>
<div>into<br>
</div>
<div><br>
</div>
<div>integer*8 IPROBLEM<br>

Hi, all!</p>

I have tried the pyipopt to run IPOPT. That works well.</p>

I am using Fortran 90 now. I look into hs071_f for the Fortran interface. I guess it is written in Fortran 77? Unfortunately, I really don't understand.</p>
