As I have no joystick, I have the 'joystick' use flag disabled. Trying to compile extreme-tuxracer, linker fails with: x86_64-pc-linux-gnu-g++ -march=native -Os -pipe -I/usr/include/freetype2 -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -std=c++11 -Wl,-O1 -Wl,--as-needed -o etr audio.o common.o config_screen.o course.o course_render.o credits.o env.o event.o event_select.o font.o ft_font.o game_config.o game_ctrl.o game_over.o game_type_select.o gui.o help.o hud.o intro.o keyframe.o loading.o main.o mathlib.o newplayer.o ogl.o ogl_test.o particles.o paused.o physics.o quadtree.o race_select.o racing.o regist.o reset.o score.o splash_screen.o spx.o states.o textures.o tool_char.o tool_frame.o tools.o track_marks.o translation.o tux.o view.o winsys.o -lGLU -lGL -lfreetype -lz -lbz2 -lpng16 -lSDL -lpthread -lSDL_image -lSDL -lpthread -lSDL_mixer -lSDL -lpthread -lGL -lGLU winsys.o: In function `CWinsys::InitJoystick()': winsys.cpp:(.text+0x380): undefined reference to `SDL_NumJoysticks' winsys.cpp:(.text+0x39e): undefined reference to `SDL_JoystickEventState' winsys.cpp:(.text+0x3a5): undefined reference to `SDL_JoystickOpen' winsys.o: In function `CWinsys::PrintJoystickInfo() const': winsys.cpp:(.text+0x565): undefined reference to `SDL_JoystickName' winsys.cpp:(.text+0x575): undefined reference to `SDL_JoystickNumButtons' winsys.cpp:(.text+0x5d0): undefined reference to `SDL_JoystickNumAxes' winsys.o: In function `CWinsys::CloseJoystick()': winsys.cpp:(.text+0x4e2): undefined reference to `SDL_JoystickClose' collect2: error: ld returned 1 exit status Looking into the ebuild, IUSE is empty and there is: RDEPEND="virtual/opengl virtual/glu media-libs/libsdl[X,sound,video] media-libs/sdl-mixer[vorbis] media-libs/sdl-image[png] media-libs/freetype:2" If the code cannot be fixed to check for joystick support and properly disable it[*], then at least the dependencies should make the joystick support mandatory like this: - media-libs/libsdl[X,sound,video] + media-libs/libsdl[X,joystick,sound,video] [*] to me, it looks like just a few ifdefs in winsys.cpp, but I have no clue about the configure magic, so no patch suggested, sorry ...
fixed. thanks for the bug report.
