[Rcpp-devel] Error in RCpp and Wt toolkit
Hi Dirk, thank for your support. I'm using: Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.39-2 i686 GNU/Linux Debian 7.0 wheezy G++: 4.7.2 STL: 4.7.2 BOOST: 104900 Wt: 3.2.3 R version 2.15.1 (2012-06-22) Platform: i486-pc-linux-gnu (32-bit) RInside_0.2.10 Rcpp_0.10.3 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.

For starters, please learn to write meaningful bug reports. Yours is concise (a plus) but I don't have time to chase around different websites. On my _stock Ubuntu 12.10_ I just rebuilt RInside (both 0.2.10 and the SVN version 0.2.10.1 I have here), and run make inside examples/wt -- and it works just fine in both cases. Try http://dirk.eddelbuettel.com:8088 to play with it. You need to tell us (at a minimum) what OS and release, what Rcpp version, what RInside version, possibly what Wt version etc pp. I reckon that the code is fine, but that something is amiss from your build.
