Bug ID: 95392
Summary: Build failure on MinGW
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: markus.boeck02 at gmail dot com
Target Milestone: ---
Current trunk version of GCC (tested with HEAD at
4833c1adc3c7b125bf1c59e8bd8d802ac3b0d205) fails to build using MinGW. The
compiler error is as follows:
In file included from
/mnt/c/GCC-Build/gcc/build/x86_64-w64-mingw32/libstdc++-v3/include/filesystem:45,
from ../../../../../libstdc++-v3/src/c++17/fs_ops.cc:32,
from ../../../../../libstdc++-v3/src/c++17/cow-fs_ops.cc:26:
/mnt/c/GCC-Build/gcc/build/x86_64-w64-mingw32/libstdc++-v3/include/bits/fs_path.h:
In function 'std::filesystem::path std::filesystem::u8path(const _Source&)':
/mnt/c/GCC-Build/gcc/build/x86_64-w64-mingw32/libstdc++-v3/include/bits/fs_path.h:789:32:
error: '_S_string_from_iter' is not a member of 'std::filesystem::path'
789 | std::string __s = path::_S_string_from_iter(__source);

succeed

Oops, I meant to check it on mingw-w64 before pushing that commit.

commit r11-777-gcd3f067b82a1331f5fb695879ba5c3d9bb2cca3a

libstdc++: Fix filesystem::u8path for mingw targets (PR 95392)
When I refactored filesystem::path string conversions in
r11-587-584d52b088f9fcf78704b504c3f1f07e17c1cded I failed to update the
mingw-specific code in filesystem::u8path, causing a bootstrap failure.
This fixes it, and further refactors the mingw-specific code along the
same lines as the previous commit. All conversions from UTF-8 strings to
wide strings now use the same helper function, __wstr_from_utf8.
PR libstdc++/95392
* include/bits/fs_path.h (path::_S_to_string): Move to
namespace-scope and rename to ...
(__detail::__string_from_range): ... this.
[WINDOWS] (__detail::__wstr_from_utf8): New function template to
convert a char sequence containing UTF-8 to wstring.
(path::_S_convert(Iter, Iter)): Adjust call to _S_to_string.
(path::_S_convert_loc(Iter, Iter, const locale&)): Likewise.
(u8path(InputIterator, InputIterator)) [WINDOWS]: Use
__string_from_range to obtain a contiguous range and
__wstr_from_utf8 to obtain a wide string.
(u8path(const Source&)) [WINDOWS]: Use __effective_range to
obtain a contiguous range and __wstr_from_utf8 to obtain a wide
string.
(path::_S_convert(const _EcharT*, const _EcharT)) [WINDOWS]:
Use __wstr_from_utf8.
