[Rcpp-devel] Help on compilation of Rcpp and RInside

[deqiang sun]

Hi Dirk,
Thanks for your help.
I did not see that there's a Makefile in the example folder:) I felt like an idiot. 
I just put Makefile under Eclipse source folder and it compiles/links. All tests passed, though I have to remove older version of R and install the required newer version of R to avoid the embeded R interpreter error.
By the way, I posted twice because I did not receive the email I sent and thought it is failed to mail out. Of couse, I then found out I was on the digest mode.
Best regards,
Deqiang Sun
