<DIV>Hi Jochen,</DIV>
<DIV> </DIV>
<DIV>That error is from here <A

<DIV>because the define ERROR_LOADLIB was set. That define was set here</DIV>
<DIV><A

<DIV>because the defines HAVE_WINDOWS_H and HAVE_DLFCN_H were not set.</DIV>
<DIV> </DIV>
<DIV>When building Ipopt manually or from project files in MSVC, most of these
defines have to be set by hand and apparently a few of them are missing in the
recent download. Running Ipopt’s configure script would have set these for you,
but that needs Cygwin or MSYS on Windows. If you check
include/coin/config_ipopt.h, you can see the 3.9.2 version looks more like a
full configure-generated header with all the defines, but in the 3.11.0 version
it is much shorter.</DIV>
<DIV> </DIV>
<DIV>Making an MSVC DLL with the autotools (so running configure in Cygwin or
MSYS, but telling it to use MSVC as the compiler) is a goal we’re slowly working
on - there’s a lot of discussion on the prerequisite of updating the autotools
for all COIN-OR projects here <A

but it’s a big task and progress has been slow the last few months.</DIV>
<DIV> </DIV>
<DIV>What are you trying to do with the Ipopt dll? If you’re trying to just use
the plain C interface, I could compile and post a Windows dll using MinGW (this
was made simpler to do in 3.11.7) but it will depend on the GCC runtime
libraries, and the import libraries are generated in a different form by MinGW
than MSVC (.dll.a instead of .lib). I don’t have Intel Fortran or experience
using the Visual Studio project files, but maybe someone else could help
there.</DIV>

<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

contain a ipopt.dll to which i can dynamically link. When i download the

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>Regards<BR>Jochen
