My guess is that libtbb12 lacks some shlib dependency, but I have little idea where __atomic_* symbols come from. > Additionally, r-cran-rcppparallel failed on mipsel [4] and mips64el > [5] with the following: > > /usr/bin/ld: cannot find -ltbbmalloc: No such file or directory > collect2: error: ld returned 1 exit status > > This seems related to #1011112 [6]. What needs to happen here? libtbbmalloc2 is not provided for mips* architectures. I guess bin:r-cran-rcppparallel should be RMed from mips* then.
