Hi Pat, Thank you. In order to answer to your question, my project use CMake. For now, I have installed git and download paraview sources. I have changed to branch live-data, and I am doing a git submodule update (I am seeing it is downloading vtk sources) Next I have to configure cmake, which option must be activated for my case ? After, I will do a make in order to compile paraview... And after ? How can I test paraview with live data ? What have I to do with libvtkCoProcessor.so library ? My project use system of shared memories. Is it possible to create a function into the coprocessor library so that the function read a shared memory and update paraview view ? Have you an example, because the work I have to do isn't very clear ! Thank you !
