Cannot load: undefined symbol tbb::task::note_affinity #183
Description
Are we sure that nothing is required on Linux?
Lines 92 to 93 in 0da9610
I cannot load the markovchain package (cc @spedygiorgio), which links against RcppParallel, with the following error:
Error: package or namespace load failed for ‘markovchain’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/usr/local/lib/R/library/markovchain/libs/markovchain.so':
/usr/local/lib/R/library/markovchain/libs/markovchain.so: undefined symbol: _ZN3tbb4task13note_affinityEt
So somehow this TBB symbol ends up in the markovchain library. Manually adding -ltbb to the linking phase solves the issue for me, but currently RcppParallel::RcppParallelLibs() returns nothing for Linux.

We can compare notes, I can on the courtesy Linux VM I use for Rcpp testing which has a ton of packages in
~/tmp/lib:All CRAN, all current, on Debian testing (also current).

With system or bundled tbb? I'm using the system tbb here via TBB_LIB and TBB_INC.
eddelbuettel commentedon Sep 5, 2022
Ah yes, I am likely using the bundled one.

Then that's most probably the issue. It should be easy to fix the behavior of
LdFlags()depending on whether the package was built using a user-provided TBB_LIB, or an auto-detected one as proposed in #178. I'll look into this when I find time.Enchufa2 commentedon Jan 24, 2023
Cannot reproduce this anymore.
