It seems we have a libvirt PKGBUILD but no released package. Here is the MSYS2 approach to software development, shamelessly taken from ArchLinux. Could you try this: pacman -Ss base-devel mingw-w64-x86_64-toolchain git clone https://github.com/Alexpux/MINGW-packages.git cd MINGW-packages/mingw-w64-libvirt MINGW_INSTALLS=mingw64 makepkg-mingw -s pacman -U *pkg*xz .. and if it doesn't work file a ticket on: https://github.com/Alexpux/MINGW-packages/issues https://github.com/Alexpux/MINGW-packages/issues .. otherwise you should have an MSYS2 libvirt. even if it does work, file a bug asking that mingw-w64-libvert gets packaged. You really should not mix binaries from different ecosystems and compilers. I do not know how TDM configure their compilers or how Fedora configures theirs (exception models, C++ ABIs) but it is a risky business and I caution strongly against it. All your packages should be compiled with the same toolchain. Why would you use TDM compilers anyway? MSYS2 comes with its own: pacman -S mingw-w64-x86_64-toolchain gets you the 64-bit version.
