Hi Dirk, thank for your support.
Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.39-2 i686 GNU/Linux
Debian 7.0 wheezy
R version 2.15.1 (2012-06-22)
Platform: i486-pc-linux-gnu (32-bit)
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.
