Building DXVK's DLLs on Gentoo
By far the easiest way to do it is on a Debian chroot, but that ain’t as fun as building your own toolchains and do it on Gentoo.
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
# emerge virtual/wine dev-util/meson dev-util/glslangMinGW64
MinGW with POSIX threads is needed, problem is by default crossdev will compile GCC with Win32 threads.
Start by creating your toolchains, tuple for x86 is i686-w64-mingw32 and x86_64-w64-mingw32 for x64.
# crossdev -t i686-w64-mingw32
# crossdev -t x86_64-w64-mingw32Fix GCC by enabling POSIX threads and adding the libraries USE to mingw64-runtime.
# 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_threadscross-i686-w64-mingw32/mingw64-runtime libraries
cross-x86_64-w64-mingw32/mingw64-runtime librariesRebuild mingw64-runtime and gcc. Order matters, mingw64-runtime with libraries provides pthreads.h and other stuff that is needed to compile GCC with 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/gccDepending on the runtime version, libraries may end up in the wrong place (see bug #653246), if that is the case sysmlink those and then rebuild GCC. eg
# 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
# x86_64-w64-mingw32-gcc -v
