[Ipopt] ipopt build : unresolved external symbol _SetIpoptCallbackFunction

[Moncade, Fabrice]

Hi Stefan, and Toni,

First of all, many thanks for the quick feedback.

To Stefan: yes I am trying to build Ipopt in a "non-supported" way in order to be able to test the inexact algorithm on my specific problem.

To Toni: I have read a lot about the inexact algorithm, and I kind of convinced myself that it might be worth a try on my specific problem. Nonetheless, I understand now, that I would have to get the "official Pardiso" by opposition to the "MKL Pardiso" if I want to get a real chance of trying it. I thought it would be possible with MKL Pardiso, until I hit that linking issue. I appreciate having received your confirmation on the matter.

Cheers,
Fab.

Hi,

Pardiso in MKL does not include the callback function that Ipopt is looking for.
However,  IpIterativePardisoSolverInterface.cpp should only be compiled if configuring with --enable-inexact-solver, in which case configure should also have figured that your Pardiso lib does not fit. Thus, either there is a bug in configure (workaround by not using --enable-inexact-solver), or you use some selfmade buildsystem, which isn't supported.

Therefore, I have been able to export the following functions:  Pardisoinit, pardiso, pardiso_getenv, pardiso_setenv, mkl_pardiso_pivot, pardiso_getdiag, pardiso_handle_store, pardiso_handle_restore, pardiso_handle_delete. When linking, I get an unresolved external symbol corresponding to SetIpoptCallbackFunction. This function appears in IpIterativePardisoSolverInterface.cpp, but is not define anywhere. In the Ipopt source code, a comment indicates that : "The following global function pointer is defined in the Pardiso library".
