Hi, Thank you for reporting.
The issue is that the error is not catched at build time. It is not expected. This package should fail and not say "successfully built". Well, this needs more investigation. --8<---------------cut here---------------start------------->8--- $ guix build r-rgdal --check --no-grafts -K [...] phase `install' succeeded after 19.0 seconds starting phase `check' Testing examples for package ‘rgdal’ /gnu/store/dnb6fzp5295fcda66dnjk2y51mcva20f-r-minimal-3.6.2/lib/R/bin/BATCH: line 60: 598 Segmentation fault ${R_HOME}/bin/R -f ${in} ${opts} ${R_BATCH_OPTIONS} > ${out} 2>&1 [...] successfully built /gnu/store/7spmagnk5fycwxsigdypwkmk4kazbw7a-r-rgdal-1.4-8.drv note: keeping build directory `/tmp/guix-build-r-rgdal-1.4-8.drv-0' /gnu/store/dgkyzlasbqsxcsfk3n3bgmhrpg447f55-r-rgdal-1.4-8 --8<---------------cut here---------------end--------------->8--- Good catch! :-) All the best, simon -- $ guix describe Generation 68 Jan 16 2020 15:57:09 (current) guix d14e474 repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: d14e4745b36a835c6babd5b5f5562e12294cd9cf
