Do you have gawk installed?

Thanks you, it works perfectly. However when I want to compile my project with ocaml-windows, dune don’t recognize packages that I use :

uwu@uwu:~/Documents/LA BACKUP/POcaml$ dune external-lib-deps --missing -x windows POcaml.exe
Error: The following libraries are missing in the 4.11.2.windows context:
- tsdl
- tsdl_image
- tsdl_ttf
Hint: try: opam install tsdl tsdl_image tsdl_ttf

I tried opam install tsdl tsdl_image tsdl_ttf but it didn’t work.
Thanks.

What exactly did not work ?
