boost 1.75

[jamesoncollins]

Have you tested out to boost 1.75 yet? I see in asio-compat.h that there are some references to changes to ASIO around version 1.7.

I'm seeing these messages:

../include/goby/acomms/modemdriver/iridium_shore_rudics.h:113:81: error: no matching function for call to ‘boost::asio::basic_stream_socket<boost::asio::ip::tcp>::basic_stream_socket(const boost::asio::executor&)’
  113 |         : socket_(executor), remote_endpoint_str_("Unknown"), packet_failures_(0)

and

/usr/include/boost/asio/impl/executor.hpp:104:15: error: ‘class boost::asio::execution::any_executor<boost::asio::execution::context_as_t<boost::asio::execution_context&>, boost::asio::execution::detail::blocking::never_t<0>, boost::asio::execution::prefer_only<boost::asio::execution::detail::blocking::possibly_t<0> >, boost::asio::execution::prefer_only<boost::asio::execution::detail::outstanding_work::tracked_t<0> >, boost::asio::execution::prefer_only<boost::asio::execution::detail::outstanding_work::untracked_t<0> >, boost::asio::execution::prefer_only<boost::asio::execution::detail::relationship::fork_t<0> >, boost::asio::execution::prefer_only<boost::asio::execution::detail::relationship::continuation_t<0> > >’ has no member named ‘defer’; did you mean ‘prefer’?
  104 |     executor_.defer(BOOST_ASIO_MOVE_CAST(function)(f), allocator_);

I think this is a workaround:

• bump the boost version in asio-compat.h so that 1.75 gets the io_service
• use this macro to fix get_io_service():

• #if BOOST_VERSION >= 107000
  #define GET_IO_SERVICE(s) ((boost::asio::io_context&)(s).get_executor().context())
  #else
  #define GET_IO_SERVICE(s) ((s).get_io_service())
  #endif

Thanks, I haven't tried 1.75 yet, though I wish ASIO would stop messing around with their API seemingly every release.

If you have a working workaround, please put up a pull request.

Thanks! -Toby

I'm still testing it, but here is the possible patch:

This simpler patch seems to do it:
