Unable to build in Ubuntu 20 #213

Closed iamsh4shank closed 6 months ago

I am trying to build in Ubuntu 20 but getting errors for the coroutines.

Error Log -

I tried checkingout to cpp17 but gave me error for the tinyformat package.

Hi, there are three options:

  1. Update your compiler to a version that supports C++20 (and thus coroutines)
  2. Ensure submodules are in sync after checking out the C++17-compatible tag. To do this, run git submodule sync followed by git submodule update --init --recursive after having checked out cpp17
  3. Use the precompiled app image from the releases page.

Highlighting me is superfluous, by the way — maintainers get notified of issues in any case — and comes off as impolitely impatient.

Hi, sorry for being impatient, I was quite stuck with this for a long time. Also thank you for the help the solution worked for me.
