<font size=2 face="sans-serif">Thank you so much for your prompt response.</font>
<br>
<br><font size=2 face="sans-serif">In your summary list below, it looks
like what is being provided is a direct binary executable. Unfortunately,
in order to interface with JNI, we need a Windows shared library, that
is, a DLL file, not an EXE file. Is this provided in the Windows
binary distribution?</font>
<br>

<br><font size=3>Hi,<br>
<br>
I think that the CoinBinary project has much of what you want:<br>
</font><font size=3 color=blue><u><br>
</u></font><a href="https://projects.coin-or.org/CoinBinary"><font size=3 color=blue><u>https://projects.coin-or.org/CoinBinary</u></font></a><font size=3><br>
<br>
They have numerous coin-or project (including cbc in CoinAll) compiled
in various compilers.<br>
<br>
I would recommend to download coinall:</font><font size=3 color=blue><u><br>

We have a working Cbc application running on Linux. It is unusual
in that it is not standalone, but rather is a component of a server that
accepts requests containing MIP problems, and returns the solutions to
the client.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
The server layer is implemented in Java, and we used JNI to connect to
the solver layer, which is mostly Cbc with a few interface functions pasted
on the top.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
We were able to adapt the example makefiles in Cbc/examples, to produce
shared libraries (.so files) instead of direct executables. Shared
libraries are required to interface with Java code via JNI.</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
Now our problem:</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
We would like to port our MIP server to Windows. On Windows, shared
libraries are .dll files. Has anyone out there in Cbc-land successfully
compiled a Cbc application to produce a .dll? We are especially interested
in talking to anyone with a JNI-based success story. (We are willing
to use a Microsoft development environment, or Cygwin, or MinGW ... anything
that works. Extra points if we don't have to deliver a lot of extra
runtime support software when we install the server on a new machine.)</font><font size=3>
