Overview

About

Maintained by Hongyuan JiaCRAN page ↗GitHub ↗Website ↗Issues ↗

Provides a cross-platform framework for dynamic binding of C libraries using a flexible Foreign Function Interface (FFI). The FFI supports almost all fundamental C types, multiple calling conventions, symbolic access to foreign C struct/union data types and wrapping of R functions as C callback function pointers. Dynamic bindings to shared C libraries are data-driven by cross-platform binding specifications using a compact plain text format; the package includes a 'DynPort' binding specification for 'SDL3' generated from current headers with 'porter'. The package includes a variety of technology demos and OS-specific notes for installation of shared libraries. For the underlying methods and bundled 'DynCall' libraries, see Adler (2012) doi:10.32614/RJ-2012-004 and Adler and Philipp (2008) https://dyncall.org.

Changes in 0.10.2

Make dynunload() idempotent after explicit unloads so finalizers do not attempt to unload the same dynamic library handle twice (#71).
Restore the manual R-hub workflow so valgrind checks can start from GitHub Actions (#73).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("rdyncall", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("hongyuanjia/rdyncall")

Development version from hongyuanjia/rdyncall. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-rdyncall

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-rdyncall

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-rdyncall

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
