It is probably Qt 5 that makes the difference. Why did you pick it? Ubuntu 12.04 and 12.10 comes with perfectly fine versions of Qt 4.7.* | Now rinsides's qtdensity example does not work anymore, for two reasons: | 1) The file main.cpp does not compile.

That one is weirder. If we both use Rcpp 0.10.3, why do you have this and I don't? Do the other examples (in the neighbouring directories) build? | which I do not now how to solve. What should I do? Debug it. It broke, and you get to keep the pieces. I support software I give away for free. I test to the best of my ability and resources, but keep in mind that I do not have the manpower or resource to test on every conceivable combination of related software releases. I really do think that you safest bet may to take the libqt* versions from your distro. | Once you tell me how to fix this I will build an example with qt in which I | use Rcpp to reproduce the results in a finance paper which were obtained | originally in matlab.
