Hi All, I have downloaded Boost 1.63 the second time. On my home computer, building it yielded all libraries. However, I do similar now at work, and it won't build Asio. First I do ./bootstrap.sh --with-libraries=all Then I build, but these are the results: balazs@bamer-debian:/opt/boost-1.63$ ls stage/lib/ |grep asio|wc 0 0 0 Although there are cpp files, that should be turned into a linbrary: balazs@bamer-debian:/opt/boost-1.63$ find |grep asio |grep cpp$|wc 214 214 9862 Asking bootstrap about what it would do shows it is not willing to build Asio: balazs@bamer-debian:/opt/boost-1.63$ ./b2 --show-libraries The following libraries require building: - atomic - chrono - container - context - coroutine - coroutine2 - date_time - exception - fiber - filesystem - graph - graph_parallel - iostreams - locale - log - math - metaparse - mpi - program_options - python - random - regex - serialization - signals - system - test - thread - timer - type_erasure - wave What should I do? Is there a dependency missing? Thank you in advance. Best regards: Balazs
