AsioHeaders: Asio Headers for R

CI License CRAN Downloads Last Commit


This package provides R with access to Asio header files. Asio provides a cross-platform C++ library for network and low-level I/O programming. It is also included in Boost – but requires linking when used as part of Boost. This standalone version of Asio is a header-only C++ library which can be used without linking (just like our BH package with parts of Boost).

By providing the Asio library in this package, we offer a more efficient distribution system for CRAN as replication of this code in the sources of other packages is avoided.

To use it, simply add it to the LinkingTo: field in the DESCRIPTION field of your R package—and the R package infrastructure tools will then know how to set include flags correctly on all architectures supported by R.


The RcppAsioExample package provides a simple illustration and example of using this package. Use it to both assert your compiler and setup are working correctly, and possibly extend your work from. Generally speaking, only a LinkingTo: AsioHeaders should be needed, plus on Windows only a very simply link instruction in src/
