undefined reference to `std::filesystem::create_directories(std::filesystem::__cxx11::path const&)' about neoleo HOT 4 CLOSED

My suspicion is that with an older compiler like 8.3.0, you need to add an extra compile flag like -lstdc++fs (unconfirmed), as they don't implement the full C++17 standard. I will investigate the problem and get back to you.

from neoleo.

Here's a fix:

make clean
env LIBS=-lstdc++fs ./configure
make

I'll note these instructions in installation notes. I'm reluctant to incorporate this fix in with configure.ac because I consider the g++ 8.3.0 "outdated". My inclination is therefore to let a maintainer provide tweaks to the system until a more modern compiler is released, whereupon the problem will vanish.

Is that a satisfactory response for you?

The fix works for me. Since there has been no response from original poster, I will close this issue.

This workaround (LIBS=-lstdc++fs) works for me with gcc 8.4.0 from Arch Linux' community repo.
