<P><FONT SIZE=2>Dear all,<BR>
<BR>
i want to gather some information regarding the state of the precompiled binaries. The following files can be found on the webpage<BR>
<BR>
[ ]Ipopt-3.11.1-mac-osx-x86_64-gcc4.5.3.tgz 15-Jun-2013 08:42 4.5M <BR>
[ ]Ipopt-3.11.1-win32-cl16ifort13.1.zip 15-Jun-2013 08:42 8.1M <BR>
[ ]Ipopt-3.11.1-win64-intel13.1.zip 15-Jun-2013 08:42 9.9M <BR>
[ ]Ipopt-3.11.3-win32win64-matlabmexfiles.zip 30-Aug-2013 18:05 3.6M <BR>
<BR>
<BR>
There are some problems with these files for me. None of these files contain a ipopt.dll to which i can dynamically link. When i download the following file<BR>
<BR>
[ ]Ipopt-3.11.0-Win32-Win64-dll.7z 24-May-2013 14:49 7.0M <BR>
<BR>
extract it, and use lib\Win32\ReleaseMKL\ipopt-vc10.dll in my project i get the following error, when specifying linear_solver="ma57" (with MUMPS everything works fine):<BR>
<BR>
Exception of type: OPTION_INVALID in file "..\..\..\src\Algorithm\IpAlgBuilder.c<BR>
pp" at line 343:<BR>
Exception message: Selected linear solver MA57 not available.<BR>
Tried to obtain MA57 from shared library "libhsl..dll", but the following error<BR>
occured:<BR>
loadLib error: Do not know how to handle shared libraries on this operating syst<BR>
em<BR>
<BR>
<BR>
When i download this file, everything works fine (MUMPS and MA57):<BR>
[ ]Ipopt-3.9.2-win32-win64-dll.7z 19-Sep-2011 20:02 7.2M <BR>
<BR>
Can anybody tell me what happened during releases?<BR>
Why was the version 3.11.0 build without support for the dynamic library loader?<BR>
Why is the ipopt*.dll file not included in the newer releases?<BR>
When is the next binary release scheduled and could this again included a .dll for Windows systems?<BR>
<BR>
I would be really grateful to receive some insight on this problems. Right now everything works fine with IPOPT 3.9.2, but i would like to use the newer version with the HSL routines. I would also be very thankful for a compiled binary for windows of IPOPT 3.11.0 or above.<BR>
<BR>
