Hi Laurent, thanks for the answer. I have both libsdl_ttf2.0 and libsdl_ttf2.0-dev installed. libSDL_ttf-2.0.so.0.6.3 located in /usr/lib SDL_ttf.h located in /lib/include I had no configure problem till rev 3909. Did you change something starting with rev3910? No entry found in Changelog for SDL component. Regards, Emanuele
