Bug ID: 89986
Summary: [9 Regression] missing export for
directory_iterator::increment
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: link-failure
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
#include <filesystem>
int main()
{
std::error_code ec;
std::filesystem::directory_iterator it("/", ec);
it.increment(ec);
}
Using GCC 8 and linking to libstdc++fs.a this works, but using GCC 9 it
doesn't:
/usr/bin/ld: /tmp/ccC5CJow.o: in function `main':
/tmp/dir.cc:7: undefined reference to
`std::filesystem::__cxx11::directory_iterator::increment(std::error_code&)'
collect2: error: ld returned 1 exit status
I forgot to export that symbol after moving the definitions to libstdc++.so
(and apparently never tested it!)
