Looks good, and is always identical at my end. With Ubuntu I have Wt 3.2.1 but I am not sure how / why that would matter. | Rcpp for Qt works perfectly, but as I said, for Wt, after running, the | system throw an segmentation error. | | If I comment line 171 [R_.parseEvalQ(cmd);]; I not get crash after | running, but not generate image. Sure. It's the invocation of R that creates the issue, and creates the image. You could try the code in examples/threads/ which is close in spirit. If that works, and if Qt works, then it may be Wt, but you will have to debug at your end -- as it works here.
