Reconstruct igraph object formats for old versions of igraph.
Version 1.2.4.2 and older (2019-11-27) give the following error on my system:
/opt/homebrew/bin/gfortran -fno-optimize-sibling-calls -fPIC -Wall -g -O2 -c dgetv0.f -o dgetv0.o
dgetv0.f:404:38:

Trying to install older igraph versions in an Ubuntu 18.04 Docker container. Build with:
docker build --platform linux/amd64 -t rigraph-forensics bionicOr get from GHCR with:
docker pull --platform linux/amd64 ghcr.io/krlmlr/rigraph-forensicsRun container with:
docker run --rm -ti --platform linux/amd64 -v $(pwd):/rigraph-forensics rigraph-forensicsIn the container, via functions defined in the image's ~/.Rprofile:
# Run in same R process:
R -q -e 'run_igraph("1.4.3", make_ring(3, directed = TRUE))'
# Start a new R process:
R -q -e 'call_igraph("1.4.3", make_ring(3, directed = TRUE))'
