Package: g++-mingw-w64-i686 Version: 8.2.0-1+21~exp2 Severity: normal Including filesystem header results in compilation errors, e.g.:
% echo '#include <filesystem>' | i686-w64-mingw32-g++ -std=c++17 -x c++ - In file included from /usr/lib/gcc/i686-w64-mingw32/8.2-win32/include/c++/filesystem:37, from fs.cpp:6: /usr/lib/gcc/i686-w64-mingw32/8.2-win32/include/c++/bits/fs_path.h: In member function ‘std::filesystem::__cxx11::path& std::filesystem::__cxx11::path::operator/=(const std::filesystem::__cxx11::path&)’: /usr/lib/gcc/i686-w64-mingw32/8.2-win32/include/c++/bits/fs_path.h:237:47: error: no match for ‘operator!=’ (operand types are ‘std::filesystem::__cxx11::path’ and ‘std::filesystem::__cxx11::path’) || (__p.has_root_name() && __p.root_name() != root_name())) ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~ ... This is due to the fact that Windows-specific code in this header uses operator==(path, path) which is only defined later, so the error makes sense. I'm not sure where exactly does this code come from as it differs from the upstream code (in gcc repository), but I can't find the Debian patch with it neither. FWIW it looks like using the upstream version would fix this problem. -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (990, 'unstable'), (500, 'unstable-debug'), (100, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.6.0-0.bpo.1-amd64 (SMP w/8 CPU cores) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to C.UTF-8), LANGUAGE=C.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to C.UTF-8) Shell: /bin/sh linked to /bin/dash Init: unable to detect Versions of packages g++-mingw-w64-i686 depends on: ii gcc-mingw-w64-base 8.2.0-1+21~exp2 ii gcc-mingw-w64-i686 8.2.0-1+21~exp2 ii libc6 2.27-5 ii libgcc1 1:8.2.0-4 ii libgmp10 2:6.1.2+dfsg-3 ii libisl19 0.20-2 ii libmpc3 1.1.0-1 ii libmpfr6 4.0.1-1 ii libstdc++6 8.2.0-4 ii zlib1g 1:1.2.11.dfsg-1 g++-mingw-w64-i686 recommends no packages.
