Provide visibility to mumps_c

[juanmanzanero]

Hello!

I am using ipopt to run optimal control problems (it is an open source project, fastest-lap) and I explicitly use mumps (the function mumps_c) to solve the sensitivity analysis. In linux, since I compile everything myself, I can use the mumps library compiled by myself and that I am linking ipopt with.

However, I want to provide a windows precompiled version of my software, for which I am using your precompiled ipopt libraries. Now I face the problem that I do not have mumps_c available, I guess it was maked as visibility hidden when linking ipopt. Can I ask you to provide public visibility to mumps_c?

(For example, a nice approach would be to create a function ipopt_mumps_c which can have visibility public, that simply calls mumps_c (which can stay hidden))

I would appreciate this a lot, since if I install my own mumps version, I will never be sure that it is exactly the same as in ipopt.

Thank you in advance!!! And thank you for providing such a powerful tool.

Adding a ipopt_mumps_c() sounds possible. Another option would be to build the Mumps lib as DLL (instead of a static lib that gets included into the Ipopt DLL) and to distribute also the corresponding Mumps LIB file. mumps_c() would be marked for DLL export then and you could link against the Mumps LIB file.

Thank you Stefan for the very quick answer. Both answers sound very good to me!

The binaries attached to the 3.14.7 release have MUMPS build as separate DLL and corresponding LIB and headers are redistributed.
