[Rcpp-devel] Error in Building a Package Using Rcpp

[Wonsang You]

Dear Dirk,

I appreciate you for your kind guidance.
Fortunately, I could solve the error in building an R package based on Rcpp.
The error was caused by wrong environment setting of Windows.
I added a system path as an environment variable as follows.

>set path= C:\Rtools\bin

Then, the error no longer appear again, and it was so successful. Thank you.

Best Regards,
Wonsang
