Three things broke the x86_64-w64-mingw32 build; two are real and fixed here (the third was a stale-object contamination from building Linux and Windows in the same tree, resolved by a clean rebuild — not a code fix). 1. Single-pass mingw ld could not resolve the cross-references DragonX added between the internal static archives (libbitcoin_util/common objects pulling in UniValue; util<->common mutual deps). GNU ld on Linux re-scans archives so it never surfaced; ld64 on macOS rejects the grouping flag outright. Bracket each binary's _LDADD in -Wl,--start-group/--end-group, delivered via AC_SUBST(LINK_GROUP_*) so automake does not reject the linker flag inside _LDADD, and left empty on every non-Windows target. 2. The Rust build emits the mingw archive as rustzcash.lib, but the link line asks for -lrustzcash, i.e. librustzcash.a. Normalize the staged filename to librustzcash.a for every host (a no-op on Linux/macOS, where the basename was already librustzcash.a).

Hush Dependencies
To build dependencies for the current arch+OS:
make
To build for another arch/OS:
make HOST=host-platform-triplet
For example:
make HOST=x86_64-w64-mingw32 -j4
A prefix will be generated that's suitable for plugging into Hush's
configure. In the above example, a dir named x86_64-w64-mingw32 will be
created. To use it for Hush:
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
Common host-platform-triplets for cross compilation are:
i686-w64-mingw32for Win32x86_64-w64-mingw32for Win64x86_64-apple-darwin11for MacOSXarm-linux-gnueabihffor Linux ARM
No other options are needed, the paths are automatically configured.
Dependency Options: The following can be set when running make: make FOO=bar
SOURCES_PATH: downloaded sources will be placed here
BASE_CACHE: built packages will be placed here
SDK_PATH: Path where sdk's can be found (used by OSX)
PRIORITY_DOWNLOAD_PATH: Try fetching source files from here before using their own URLs
NO_WALLET: Don't download/build/cache libs needed to enable the wallet
DEBUG: disable some optimizations and enable more runtime checking
If some packages are not built, for example make NO_WALLET=1, the appropriate
options will be passed to bitcoin's configure. In this case, --disable-wallet.
Additional targets:
download: run 'make download' to fetch all sources without building them
download-osx: run 'make download-osx' to fetch all sources needed for osx builds
download-win: run 'make download-win' to fetch all sources needed for win builds
download-linux: run 'make download-linux' to fetch all sources needed for linux builds
