<DIV>Hi ,All</DIV>
<DIV> I want to use Matlab to call IPOPT on Windows,but there is only a Matlab interface working with the old Fortran version of IPOPT,so I download the IPOPT 2.2.1 from the website(<A href="http://www.coin-or.org/download/source/Ipopt-Fortran/">http://www.coin-or.org/download/source/Ipopt-Fortran/</A>).</DIV>
<DIV> I followed the ipopt-mex interface (<A href="http://www.andrew.cmu.edu/user/steinhau/Research/mex-interfaces.html">http://www.andrew.cmu.edu/user/steinhau/Research/mex-interfaces.html</A>) installation instructions and have successfully fulfilled all of the installation procedures except the last instruction. When I carried out the last instruction( mex -f mexopts.bat -output Ipopt IpoptMexInterface.c IpoptInterfaceSup.c libipopt.a libg2c.a ),lots of errors occur:</DIV>
<DIV> libipopt.a(get_step_full.o):ccFuo9F9.f:(text+0xe4a3): undefined reference to `_dgemv_'<BR> libipopt.a(get_step_full.o):ccFuo9F9.f:(.text+0xe63b): undefined reference to `_dgesv_'<BR> libipopt.a(get_step_full.o):ccFuo9F9.f:(.text+0xe765): undefined reference to `_dgemv_'<BR> libipopt.a(get_step_full.o):ccFuo9F9.f:(.text+0xe7e1): undefined reference to `_dgemv_'.</DIV>
<DIV> I guess the thirdparty packages BLAS and LAPACK have not been compiled or linked,but I have no idea how to fix it, anybody can help me?</DIV>
<DIV> </DIV>
<DIV> Thanks</DIV>
