[Cbc] Porting JNI-based Cbc app to Windows

[acw at ascent.com]

Ah, I see!  Excellent.

The binaries only include static libraries, but I imagine I will be able 
to compile against those libraries to produce a dynamic one.  Thank you, 
Haroldo.

We would still love to hear from anyone who has successfully done 
something similar.  Surely we can't be the first to try this?

The EXE is an installer. Please look at the installed files (not sure if a 
DLL is available, but at least an static library for windows is).

Thank you so much for your prompt response. 

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? 

Thanks again.

Hi,

I think that the CoinBinary project has much of what you want:

https://projects.coin-or.org/CoinBinary

They have numerous coin-or project (including cbc in CoinAll) compiled in 
various compilers.

I would recommend to download coinall:

I will roughly describe our application and then present our problem. 

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. 


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. 

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. 

Now our problem: 

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.)
