You have been subscribed to a public bug: Since update to focal, libsdl2 and libsdl2-ttf headers have a different location, causing a compilation error when trying to include SDL2/SDL_ttf.h header :
$ sudo apt install libsdl2-ttf-dev libsdl2-dev $ echo "#include <SDL2/SDL_ttf.h>" > main.c $ gcc main.c In file included from main.c:1: /usr/include/SDL2/SDL_ttf.h:34:10: fatal error: SDL.h: Aucun fichier ou dossier de ce type 34 | #include "SDL.h" | ^~~~~~~ compilation terminated. It seems that SDL_ttf.h header expects to be in the same place that SDL ones, which is not the case : $ dpkg -L libsdl2-ttf-dev /. /usr /usr/include /usr/include/SDL2 /usr/include/SDL2/SDL_ttf.h ... $ dpkg -L libsdl2-dev /. /usr /usr/bin /usr/bin/sdl2-config /usr/include /usr/include/x86_64-linux-gnu /usr/include/x86_64-linux-gnu/SDL2 /usr/include/x86_64-linux-gnu/SDL2/SDL.h ... ** Affects: libsdl2-ttf (Ubuntu) Importance: Undecided Status: New -- libsdl2-ttf-dev and libsdl2-dev headers not at the same place, causing compilation error https://bugs.launchpad.net/bugs/1872023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
