How about doing something like this:

This is unrelated. The variable is defined here:

ion.cpp#L71-L83.

There is a missing guard in this source file and it should be resolved by the fix in PR#3402. https://github.com/STEllAR-GROUP/hpx/pull/3402 Everything else about this feature should be inert on the OSes the feature doesn't apply to. -- Lars Viklund | z...@acc.umu.se ___ hpx-users mailing list hpx-users@stellar.cct.lsu.edu https://mail.cct.lsu.edu/mailman/listinfo/hpx-users

Those #ifs still currently protect
namespace hpx_start
{
// Importing weak symbol from libhpx_wrap.a which may be shadowed by one
present in
// hpx_main.hpp.
HPX_SYMBOL_EXPORT __attribute__((weak)) extern bool include_libhpx_wrap;
}
(but I don't understand the shadowing issue...)

Chugging along trying to get hpx to compile, I thought I would try the 1.1.0 patches I had so far on master. I just got an extra compile error: /usr/src/local/hpx/src/hpx_init.cpp: In function âint hpx::detail::run_or_start(hpx::util::function_nonser&, const boost::program_options::options_description&, int, char**, std::vector >&&, hpx::startup_function_type, hpx::shutdown_function_type, hpx::runtime_mode, bool)â: /usr/src/local/hpx/src/hpx_init.cpp:603:24: error: âhpx_startâ has not been declared if(hpx_start::include_libhpx_wrap) which seems to be from commit bd77d6ed1720ba2d1c45c7129c5bf1d299a80498 Author: Nikunj Gupta Date: Wed Jul 18 09:35:54 2018 +0530 Changes according to review Would a quick glance by you suggest the #ifs served as useful protection?
