<div> Dear all,<br> I have successfully installed IPOPT 3.2.3 using cygwin on Windows.I want to use IPOPT to solve nonlinear problems modelled in SIF. I have installed CUTEr and Sifdec I defined the following environment variables: CUTER, MYCUTER,SIFDEC, MYSIFDEC, MASTSIF. I compiled the CUTEr, SifDec and IPOPT with g77.<br> I made the installion of all the above software according to their documentations (repeat again),<br>1)install cuter and sifdec<br>2)install IPOPT using cygwin on Windows(configure, make install) <br>3)make cuter<br><pre> However,I encountered the following errors: <br>1.when I type "sdipopt --blas none ROSENBR.SIF"<br>the output is as follows:<br>Problem name: ROSENBR <br><br> Double precision version will be formed. <br><br> The objective function uses 1 linear group <br> The objective function uses 1 nonlinear group <br> <br> There are 2 free variables<br> <br>/usr/share/cuter/CUTEr.large.pc.lnx.g77/double/bin/ipoptma.o:ipoptma.f:(.text+0x1f0): undefined reference to `_ipopt_'<br>collect2: ld returned 1 exit status<br>limit: Command not found.<br>/home/Administrator/ipoptmin: Command not found.<br><br>
2.when I type "sdipo --blas none ROSENBR.SIF"<br>the output is as follows:
Problem name: ROSENBR <br><br> Double precision version will be formed. <br><br> The objective function uses 1 linear group <br> The objective function uses 1 nonlinear group <br> <br> There are 2 free variables<br> <br>limit: Command not found.<br><br>Could you give some suggestions about the problems above? Thank you !<br><br> Gaoqiang<br></pre></div><br><div> </div>
