Problème makefile + librairie
Bonjour,
Voila mon probleme : Lorsque j'essaie de compiler mon projet SDL a l'aide de mon makefile cela me donne une suite de "undefine reference to.." ( pour chaque fonction SDL utilisé.
Voici mon makefile :

comme vous pouvez le constater, a priori, l'edition de lien est presente...
Voici maintenant mon fichier source :

et enfin, voici l'organisation de mon dossier de projet :
.:
include Makefile project1.c project3.c src
lib project2.c sdl-config
./include:
begin_code.h SDL_config.h SDL_image.h SDL_mutex.h SDL_syswm.h
close_code.h SDL_cpuinfo.h SDL_joystick.h SDL_name.h SDL_thread.h
SDL SDL_endian.h SDL_keyboard.h SDL_opengl.h SDL_timer.h
SDL_active.h SDL_error.h SDL_keysym.h SDL_platform.h SDL_types.h
SDL_audio.h SDL_events.h SDL_loadso.h SDL_quit.h SDL_version.h
SDL_byteorder.h SDL_getenv.h SDL_main.h SDL_rwops.h SDL_video.h
SDL_cdrom.h SDL.h SDL_mouse.h SDL_stdinc.h
./include/SDL:
begin_code.h SDL_cpuinfo.h SDL_joystick.h SDL_name.h SDL_thread.h
close_code.h SDL_endian.h SDL_keyboard.h SDL_opengl.h SDL_timer.h
SDL_active.h SDL_error.h SDL_keysym.h SDL_platform.h SDL_types.h
SDL_audio.h SDL_events.h SDL_loadso.h SDL_quit.h SDL_version.h
SDL_byteorder.h SDL_getenv.h SDL_main.h SDL_rwops.h SDL_video.h
SDL_cdrom.h SDL.h SDL_mouse.h SDL_stdinc.h
SDL_config.h SDL_image.h SDL_mutex.h SDL_syswm.h
./lib:
libSDL.a libSDL_image.la libSDL.la libSDL.so
libSDL_image.a libSDL_image.so libSDLmain.a pkgconfig
./lib/pkgconfig:
sdl.pc
Mon but etant de ne pas installer la librairie a proprement parler si possible dans le dossier /usr/lib (sous linux) et donc de travailler directement a partir des fichier present dans mon dossier.
Merci d'avance ^^
