Hello Andreas, Yes, this does seem like a local issue to r-cran-rcppparallel.
tbb and variants are loaded when r-cran-rcppparallel is imported, as seen in [hooks.R]. The function of interest is 'tbbLibPath()', which seems to depict tbb library path. With some more investigation, you can see this function within [build.R]. You can see for all supported platforms apart from Windows and Sparc systems, it seems like it expects the library to be situated under lib/ (due to the first argument used within system.file()). I'll try to write a simple patch for this hook file. For a Debian package, this assumption for library location is plain wrong. Kind regards, Shayan Doust [hooks.R]: https://github.com/RcppCore/RcppParallel/blob/b216ba27dcbd3c523932bd918b6dd0b1b08d3566/R/hooks.R#L8 [build.R]: https://github.com/RcppCore/RcppParallel/blob/b216ba27dcbd3c523932bd918b6dd0b1b08d3566/R/build.R#L66 On Tue, 8 Sep 2020 20:32:53 +0200 Andreas Tille <andr...@an3as.eu> wrote: > Control: tags -1 help > > Hi, > > any help why TBB is not found?
