Failed to build for 18.04 about island

[underdoeg]

I am fairly certain that part of this is an outdated compiler. find_if in this form is a c++17 feature and so is std::filesystem. gcc on ubuntu can be upgraded with https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa?field.series_filter=bionic
But using 20.04 is really worth it, especially with all the fine tuning gnome has received...

/home/kyle/Desktop/island/modules/le_file_watcher/le_file_watcher.cpp:11:10: fatal error: filesystem: No such file or directory
#include
^~~~~~~~~~~~

might be the crucial line here - i’ve been working on the latest version of gcc, on the latest version of ubuntu, 20.04, which i recommend - it looks like std::filesystem was not yet available in cpp outside experimental in 18.04 and its version of gcc...

I am getting this exact same issue reported by @kylemcdonald on macOS Catalina.

thanks! when i upgrade i will try again. right now i am on 18.04 for a while longer due to cuda & tensorflow compatibilities. these tend to lag a bit, maybe another 6-8 months.

I'm closing this issue as there are currently no plans for backporting to ubuntu 18.04. That said, current Ubuntu, and Arch Linux versions should work.
