<DIV>It’s probably an Ipopt compilation issue with the binaries you downloaded.
The error “Do not know how to handle shared libraries on this operating system”
comes from this line <A
title=https://projects.coin-or.org/Ipopt/browser/releases/3.11.0/Ipopt/src/contrib/LinearSolverLoader/LibraryHandler.c#L34
href="https://projects.coin-or.org/Ipopt/browser/releases/3.11.0/Ipopt/src/contrib/LinearSolverLoader/LibraryHandler.c#L34">https://projects.coin-or.org/Ipopt/browser/releases/3.11.0/Ipopt/src/contrib/LinearSolverLoader/LibraryHandler.c#L34</A>
because the define ERROR_LOADLIB was set here - <A
title=https://projects.coin-or.org/Ipopt/browser/releases/3.11.0/Ipopt/src/contrib/LinearSolverLoader/LibraryHandler.h#L29

<DIV> </DIV>
<DIV>Apparently neither of HAVE_WINDOWS_H and HAVE_DLFCN_H were defined when the
Ipopt library you’re using was compiled. You’ll need a different one. There are
some older downloads at <A title=http://www.coin-or.org/download/binary/
href="http://www.coin-or.org/download/binary/">http://www.coin-or.org/download/binary/</A>
and I have some MinGW DLL’s I made last year that may work for you, try <A
title=https://dl.dropboxusercontent.com/u/8244638/bonmin_win32.zip
href="https://dl.dropboxusercontent.com/u/8244638/bonmin_win32.zip">https://dl.dropboxusercontent.com/u/8244638/bonmin_win32.zip</A>
or <A title=https://dl.dropboxusercontent.com/u/8244638/bonmin_win64.zip
href="https://dl.dropboxusercontent.com/u/8244638/bonmin_win64.zip">https://dl.dropboxusercontent.com/u/8244638/bonmin_win64.zip</A>
(includes Ipopt, Cbc, and Bonmin). I haven’t tested these with Python. Do you
(or anybody else on the list) know whether pyipopt requires a Visual
Studio-compiled Ipopt DLL, or if it can also work with a MinGW DLL?</DIV>
<DIV> </DIV>
<DIV>I also just built a set of cross-compiled binaries on the opensuse build
service, I can give you links to those but they’re done as separate packages for
ASL, Lapack, Mumps, Ipopt, and you need to get libgcc, libgfortran etc. There’s
a package in Julia that automates this, which you might be interested in trying
out.</DIV>

<P class=MsoNormal>Hi,<o:p></o:p></P>
<P class=MsoNormal><o:p><FONT size=3></FONT></o:p> </P>
<P class=MsoNormal>I'm having issues using the pyiopt module with an external
HSL library (on Windows), and was hoping someone may know what I need to do to
remedy this?><o:p></o:p></P>
<P class=MsoNormal><o:p><FONT size=3></FONT></o:p> </P>
<P class=MsoNormal>I'm using the pyipopt python module ( <A
href="https://github.com/xuy/pyipopt">https://github.com/xuy/pyipopt</A> ),
which works fine with the last version of ipopt dlls taken from the binaries
downloads (<A
href="http://www.coin-or.org/Binaries/Ipopt/Ipopt-3.11.0-Win32-Win64-dll.7z">http://www.coin-or.org/Binaries/Ipopt/Ipopt-3.11.0-Win32-Win64-dll.7z</A>)
. I'm now running into some problems using mumps and would like to use the
HSL routines instead - e.g. ma57 which works well on a similar problem in
Matlab. I've tried with the latest HSL 2013 libraries, both a prebuilt dll
that was given to me, and a locally built version from the HSL source
code. Either way I get the following problem:<o:p></o:p></P>

Python, or Ipopt? <o:p></o:p></P>
