Bug ID: 39193
Summary: std::filesystem::path::compare fails to link
Product: libc++
Version: 7.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: vanboxem.ru...@gmail.com
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
This simple example program fails to compile with Clang/libc++ 7.0.0:
clang++ -stdlib=libc++ -std=c++17 main.c++
---
#include <filesystem>
#include <iostream>
int main()
{
std::filesystem::path p("/home");
auto p2 = p;
if(p == p2)
std::cout << "yay\n";
}
---
The errors I get are:
/usr/bin/ld: /tmp/main-da17c3.o: in function `main':
main.c++:(.text+0x31d): undefined reference to
`std::__1::__fs::filesystem::path::__compare(std::__1::basic_string_view<char,
std::__1::char_traits<char> >) const'
clang-7: error: linker command failed with exit code 1 (use -v to see
invocation)
Nothing changes if I
- add -lc++experimental (it seems std::filesystem has moved to plain libc++ in
7.0?)
- compile and link in separate steps
This worked fine with Clang/libc++ 6.0.1 before.
All this is on Arch Linux.
