Hello!
After several compilations of messagepack to linux/arm, linux/x64 and some others I turned to linux/mips platform with toolchain-mipsel_24kc_gcc-12.3.0_musl.
In my case Messagepack is included in shared library that's being used by application.

So while compiling application I'm getting error:

mipsel-openwrt-linux-musl/bin/ld: libnodesd.so: undefined reference to msgpack::v1::adaptor::object<decltype(nullptr), void>::operator()(msgpack::v2::object&, decltype(nullptr) const&) const

Digging with nm shows that mentioned symbol is really undefined in library:

nm -D --demangle ./libnodesd.so | grep "msgpack::v1::adaptor::object<decltype(nullptr), void>::operator()"
U msgpack::v1::adaptor::object<decltype(nullptr), void>::operator()(msgpack::v2::object&, decltype(nullptr) const&) const

Everything is fine when compiling with regular x64 gcc, linaro arm crosscompiler and others.

I would be very appreciated for any clues to resolve error.
