# emerge -pv1 dev-lang/R ... [ebuild R ] dev-lang/R-4.0.4::gentoo USE="X jpeg nls openmp perl png readline static-libs tiff -cairo -doc -icu -java -lapack -minimal (-prefix) -profile -test -tk" 0 KiB > Are you willing to watch "htop" in another window while the dev-lang/R > build fails to see how much memory is free? htop -u portage shows high cpu usage and low memory usage (something like less than 2%). if I use this instead of htop: # grep -m1 ^MemFree /proc/meminfo MemFree: 253332 kB I get for -j1: mean = 397662.00592 min = 196772 max = 762304 std = 161394.91895 I have put up data from some -j4 runs at: http://aspodata.se/tmp/R/ where mem4* are made with ./memwatch.pl > mem4_<run#>.log. It's columns are just seconds, MemFree, and MemAvailable, taken from: $ head -3 /proc/meminfo MemTotal: 6103628 kB MemFree: 1028012 kB MemAvailable: 2326588 kB /// from mem4_<run#>.log, I see that the minimum free memory is: run 1 203492 run 2 202392 i.e. about 200MB. build_1.log points the finger to sandbox. So it might be that there i no problem at all with R, it might be that sandbox doesn't work here. I don't know what sandbox requires from the kernel so there might be some syscall missing. I did run 2 as FEATURES="-sandbox -usersandbox" emerge -aqv1 dev-lang/R In build_2.log it just says Segment fault in the vincinity of NEWS.2.rds, NEWS.rds, base.Rdts, and methods.Rdts. The first two is mentioned in doc/Makefile, and the latter two in src/library/Makefile. Going into doc and src/library and makeing thoose four works without any errors. Regards, /Karl Hammar
