Error compiling on GNU/Linux (Ubuntu)


Firstly, thank you very much indeed for your efforts in providing this wonderful tool to the R "community". I'm trying to install it on a 32-bit GNU/Linux environment (Ubuntu Maverick, to be precise) with R 2.12.0. When compiling from source the build fails because it can't find the function or variable "errno". Is there are fix or workaround available? Thanks again,

Yup, sorry about that. We

Yup, sorry about that. We caught that bug today. Try using the installer script again, I think I fixed it.

Works a treat. Compiles

Works a treat. Compiles error-free. You're a star, Michael! Thank you so much for your work on this.
