Hi, was there anybody able to use IPOPT with Pardiso and gcc 4.3.1? I guess the new gfortran libs make problems. The I tried to use MUMPS and MA27 but miss some fortran functions. I guess this is, because I use Intels MKL (blas/lapack) in the final application. Is anyone using IPOPT with gcc 4.3.x? Thanks, Fabian
