By far the easiest way to do it is on a Debian chroot, but that ain't as fun as
building your own toolchain and do it on Gentoo.
<hr>
# Dependencies
According to the official documentation:
- wine 3.10 or newer
- Meson build system (at least version 0.43)
- MinGW64 compiler and headers (requires threading support)
- glslang front end and validator
All but MinGW you can install directly from portage:
```
emerge virtual/wine dev-util/meson dev-util/glslang
```
## MinGW64
MinGW with POSIX threads is required, problem is, by default `crossdev` will
compile GCC with Win32 threads instead of POSIX. Start by creating your
toolchain with `crossdev`, tuple for x86 is `i686-w64-mingw32` and
`x86_64-w64-mingw32` for x64:
```
crossdev -t i686-w64-mingw32
crossdev -t x86_64-w64-mingw32
```
Fix GCC by enabling POSIX threads:
```
mkdir /etc/portage/{env,package.env}
echo 'EXTRA_ECONF="--enable-threads=posix"' > /etc/portage/env/mingw32_posix_threads
echo -e 'cross-i686-w64-mingw32/gcc mingw32_posix_threads\ncross-x86_64-w64-mingw32/gcc mingw32_posix_threads' > /etc/portage/package.env/mingw32_posix_threads
```
Then add the `libraries` `USE` to `mingw64-runtime`:
```
cross-i686-w64-mingw32/mingw64-runtime libraries
cross-x86_64-w64-mingw32/mingw64-runtime libraries
```
Rebuild `mingw64-runtime` and `gcc`. Order matters, `mingw64-runtime` with
`libraries` provides `pthreads.h` and other stuff that's required to compile GCC
with the POSIX thread model.
```
emerge -1 cross-i686-w64-mingw32/mingw64-runtime cross-x86_64-w64-mingw32/mingw64-runtime
emerge -1 cross-i686-w64-mingw32/gcc cross-x86_64-w64-mingw32/gcc
```
Depending on the runtime version, libraries may end up in the wrong place (see
bug #653246), if that's the case sysmlink those and then rebuild GCC:
```sh
ln -s /usr/x86_64-w64-mingw32/usr/lib64/{libmangle.a,libpthread.a,libpthread.dll.a,libwinpthread.a,libwinpthread.dll.a,libwinpthread.la} \
/usr/x86_64-w64-mingw32/usr/lib/
```
Final result should be:
```
i686-w64-mingw32-gcc -v
... Thread model: posix ...
x86_64-w64-mingw32-gcc -v
... Thread model: posix ...
```
# Crosscompiling DLLs
```
git clone https://github.com/doitsujin/dxvk.git
cd dxvk
### 32-bit build. For 64-bit builds, replace
### build-win32.txt with build-win64.txt
### build.w32 with build.w64
meson --cross-file build-win32.txt --prefix /some/install/prefix build.w32
cd build.w32/
meson configure -Dbuildtype=release
ninja
ninja install
```
```
ls /some/install/prefix/bin
d3d11.dll dxgi.dll setup_dxvk.sh
```
These are the toolchains I used.
```
cross-i686-w64-mingw32/binutils-2.30-r3
cross-i686-w64-mingw32/gcc-7.3.0-r3
cross-i686-w64-mingw32/mingw64-runtime-5.0.4
cross-x86_64-w64-mingw32/binutils-2.30-r3
cross-x86_64-w64-mingw32/gcc-7.3.0-r3
### symlinks from ...lib64/ -> ...lib/ required! see bug #653246
cross-x86_64-w64-mingw32/mingw64-runtime-5.0.4
