Bug ID: 46659
Summary: Support "filesystem" on Windows
Product: libc++
Version: 10.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: svnp...@gmail.com
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Using this file:
#include <filesystem>
#include <iostream>
namespace fs = std::filesystem;
int main() {
std::cout << fs::current_path() << std::endl;
}
and this compiler:
https://packages.msys2.org/package/mingw-w64-x86_64-gcc
and this command:
g++.exe -std=c++17 -static a.cpp
everything works as expected. However if I use this compiler:
https://github.com/mstorsjo/llvm-mingw
then I get this result:
lld-link: error: undefined symbol:
std::__1::__fs::filesystem::__current_path(std::__1::error_code*)
>>> referenced by
C:\Windows\TEMP\a-27a261.o:(std::__1::__fs::filesystem::current_path())
clang-10: error: linker command failed with exit code 1 (use -v to see
invocation)
its mentioned here, that the reason is because LibCxx doesnt currently support
"filesystem" on Windows:
https://github.com/mstorsjo/llvm-mingw/issues/62#issuecomment-554718348
I think if GCC support "filesystem", then LLVM should too.
