win_ros, image_transport not compiling due to class_loader

I have to use a camera which has only windows drivers (Ladybug5). I thought I can use WIN_ROS for this together with the image_transport package to publish the images over the network to a Linux system where I want to do some post processing.

I used this guide to setup WIN_ROS on a Windows 8 Host: *ttp://

After checking that the samples where working, I started to install the Dependencys for image_transport with the wstool:

wstool set image_common --git *ttps:// --version=hydro-devel
wstool set pluginlib --git *ttps:// --version=groovy-devel
wstool set class_loader --git *ttps:// --version= hydro-devel

Additionally I installed the console_bridge and poco to:


And I Added the lib paths of both to the Windows Enviroment variable


When I try to compile it I get stuck at:

Has anyone image_transport working with WIN_ROS? How?

Any suggestions how to fix it?

If its not working, what would be the next best option to transport the images over network to ROS?

Thanks allot!

Any package beyond that which win_ros is configured for hasn't been ported for windows yet. This would probably be inclusive of everything that is a library as it needs windows style declspec header least. Quite often the packages will be trying to reference posix headers or function calls and that needs porting too.

While it's not hard, it is a considerable effort. If you do wish to tackle it, you can look at the winros stacks as a reference to see what is required (ask questions on the winros mailing list) and start hacking. If it's a core ros stack, the guys at OSRF are usually pretty quick and ready to accept pull requests which assist in this effort.

Getting the publishing part of the image pipeline working would be a really useful addition to the current winros stacks.

I am trying to port class_loader lib to windows (Visual Studio). I followed the daniel´s suggestion and I tried to put some __declspec(dllexport) header declarations in plugin´s classes but nothing worked. Does anyone have some tips to help?

Hi, I think that the problem is the __attribute__((deprecated)) function attribute on line 83. I cut it and the problem disappeared. At least, this worked to me on windows xp.
