On Windows, Clang 8.0.1 refuses to compile the <filesystem> header with following errors: > In file included from ...\mingw64\include\c++\9.2.0\filesystem:37: > ...\mingw64\include\c++\9.2.0\bits/fs_path.h:636:31: error: invalid use of incomplete > type 'std::filesystem::__cxx11::filesystem_error' > _GLIBCXX_THROW_OR_ABORT(filesystem_error( > ^~~~~~~~~~~~~~~~~ > ...\mingw64\include\c++\9.2.0\x86_64-w64-mingw32\bits/c++config.h:177:49: note: expanded > from macro '_GLIBCXX_THROW_OR_ABORT' > # define _GLIBCXX_THROW_OR_ABORT(_EXC) (throw (_EXC)) > ^~~~ > ...\mingw64\include\c++\9.2.0\bits/fs_fwd.h:61:9: note: forward declaration of > 'std::filesystem::__cxx11::filesystem_error' > class filesystem_error; > ^ > 1 error generated. We can prevent Clang from complaining by moving the definition of `class filesystem_error` a few lines up. It should be at least above the definition of `u8path()`.
