- the Debian and hence derived Ubuntu package of R 4.1.0 does *not* enable LTO yet, in other words I have not yet add --enable-lto to the configure call and we use to default of 'nope' - my dev box is still 20.10; I only run 21.04 on one small machine where I have not tried to build arrow; but under 20.10 + R 4.1.0 + arrow 4.0.? the two step dance that they force on us works Dirk -- https://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
