Bug ID: 280564
Summary: graphics/poppler: fix build with libc++ 19
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: Individual Port(s)

As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.
This causes graphics/poppler to fail to compile with clang 19 and libc++
19, resulting in errors similar to:
/usr/include/c++/v1/string:820:42: error: implicit instantiation of
undefined template 'std::char_traits<unsigned short>'
820 | static_assert(is_same<_CharT, typename
traits_type::char_type>::value,
| ^
/wrkdirs/usr/ports/graphics/poppler/work/poppler-24.02.0/cpp/poppler-global.h:101:43:
note: in instantiation of template class 'std::basic_string<unsigned short>'
requested here
101 | class POPPLER_CPP_EXPORT ustring : public
std::basic_string<unsigned short>
| ^
/usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here
23 | struct _LIBCPP_TEMPLATE_VIS char_traits;
| ^
Upstream poppler has fixed this in commit b4ac7d9a [2], so add it as a
PATCHFILES entry in the Makefile, until the next version of poppler is
released.
