Boost requires TBB? #222

Closed Baksling closed 1 month ago

Baksling commented 8 months ago

When installing version 1.83.0 and including <boost/unordered/concurrent_flat_map.h>, i get an error that there is an undefined reference to TBB oneapi aka:

/usr/bin/ld: tests/CMakeFiles/parser.dir/parser_test.cpp.o: in function tbb::detail::d1::execution_slot(tbb::detail::d1::execution_data const&)': /usr/include/oneapi/tbb/detail/_task.h:169: undefined reference totbb::detail::r1::execution_slot(tbb::detail::d1::execution_data const)' /usr/bin/ld: tests/CMakeFiles/parser.dir/parser_test.cpp.o: in function tbb::detail::d1::current_thread_index()': /usr/include/oneapi/tbb/task_arena.h:454: undefined reference totbb::detail::r1::execution_slot(tbb::detail::d1::execution_data const)'

I am unable to find in the documentation that concurrent_flat_map relies on TBB, but i might be missing some build options? I am using the following command to download and install boost to my project, where i rely on the program_options and test:

Am i missing an option or component for concurrent_flat_map? I have tried adding --with-containers and --with-unordered, but the issues remain

What compiler and platform is this?

pdimov commented 8 months ago

Some versions of GCC (e.g. GCC 9) implement the standard <execution> header on top of TBB.

If that's your issue, you can try to define BOOST_UNORDERED_DISABLE_PARALLEL_ALGORITHMS and see if it helps.
