It appears boost-ptr-container also depends on boost-thread, at least with arm-windows triplet in 1.68.

[janisozaur]

Also boost-locale depends on boost-system and boost-thread

I filed boostorg/type_traits#105 which affects compilation of boost-regex and some more packages and it was fixed in boostorg/type_traits@5e7844b (a squashed version of boostorg/type_traits#106) so you may want to take that patch to fix arm builds. Subsequently, MSVC/ARM builds were added to type_traits' AppVeyor array.

Looking forward to see the problem getting resolved and merged!

@ras0219-msft I noticed your latest commit and that makes me wonder: I was recently trying to build a project using boost-iostreams and ran into lining errors regarding zlib and bzip2, like

error LNK2001: unresolved external symbol "protected: __thiscall boost::iostreams::detail::bzip2_base::~bzip2_base(void)" (??1bzip2_base@detail@iostreams@boost@@IAE@XZ)
error LNK2001: unresolved external symbol "protected: __thiscall boost::iostreams::detail::bzip2_base::bzip2_base(struct boost::iostreams::bzip2_params const &)" (??0bzip2_base@detail@iostreams@boost@@IAE@ABUbzip2_params@23@@Z)

(These errors are not mine, but look close enough)

I will try building when time allows to test with your latest change

Added

@janisozaur Thanks for filing that upstream -- I had developed an equivalent (but much longer) patch locally

Remove boost-signal (rationale: deprecated and removed in 1.69)

Unfortunately, it seems like we still have some ports depending on boost-signal, so for now we will leave it in at 1.68. It should no longer be installed by vcpkg install boost, however.

Thanks to everyone who pitched in on this, it's really exciting to see the next evolution of boost available through vcpkg!
