It is either that file, or an existing .RData you are loading by virtue of
I can run your example without a problem on an Ubuntu 9.10 box using
libhighgui-dev and all it dependents.
I used RInside from SVN, but that shouldn't matter. On the machine where I
tested this Rcpp is reasonably current but less recent than 0.7.12.

I just inserted -lhighgui right after -llapack, and it links and runs. So no
bug here with RInside.

You created a side-effect. Only you can figure out what you did or what you
have in .RData or .Rprofile or related files.
There is no problem with your simple test file.
