Hello, Ipopt experts,<br><br>I tried to modify the example fortran program hs071_f.f to solve a problem of my own, where I first read a .txt file (biv.txt) in order to give the parameter information in my object function and then used Ipopt to solve it. <br>
<br>I can successfully compile the fortran file to .exe file and the .exe file seemed to run, however, I got no output either on screen or in the .out file. I have no idea of what happened as there isn't any error message. Any help on this is greatly appreciated. <br>
<br>P.S. I am using windows XP (SP2), and used MinGW to compile Ipopt3.8.0. (I want to use some feature of Fortran 90).<br><br>Regards,<br><br>Sheldon<br><br><br>
