Builds the igraph static library for use in R/Bioconductor packages. This is primarily intended for R packages that wrap other C/C++ libraries that depend on the igraph C library and cannot easily be modified to use the usual R bindings to igraph. By vendoring in the source code, we reduce our susceptibility to out-of-release-schedule changes in results due to igraph updates. It also allows developers to access functionality that might yet not be available from the R bindings.
For downstream package developers, use of Rlibigraph is as simple as adding:
LinkingTo: Rlibigraph
to the DESCRIPTION, and setting:
RIGRAPH_LIBS=$(shell "${R_HOME}/bin${R_ARCH_BIN}/Rscript" -e 'Rlibigraph::pkgconfig()'")
PKG_LIBS=$(RIGRAPH_LIBS)in the src/Makevars.
We can update the vendored copy of the source code with:
VERSION=0.10.13
url=https://github.com/igraph/igraph/releases/download/${VERSION}/igraph-${VERSION}.tar.gz
curl -L ${url} > sources.tar.gz
