When trying to compile crsfml (Approach 1) I keep getting the following error:

Tried to compile on Manjaro Linux
Crystal 0.26
SFML version 2.5

Not really sure what other details I should provide 😨

Yep, seems like Crystal 0.26 is broken. I have no clue what it wants from me.
You can try using pre-generated sources from the other branch, though.
