SDL_sndioaudio.c：未定义对'sio.*&x27'的引用； 我在编译一个具有Delbian Reals/P>OpenAL和SDL2依赖关系的C++项目时遇到了一个问题 libs/openal/libopenal.a(sndio.c.o): In function `sndio_stop_playback': sndio.c:(.text+0x4b): undefined reference to `sio_stop' libs/openal/libopenal.a(sndio.c.o): In function `sndio_start_playback': sndio.c:(.text+0xcf): undefined reference to `sio_start' sndio.c:(.text+0x15c): undefined reference to `sio_stop' libs/openal/libopenal.a(sndio.c.o): In function `sndio_proc': sndio.c:(.text+0x278): undefined reference to `sio_write' libs/openal/libopenal.a(sndio.c.o): In function `sndio_reset_playback': sndio.c:(.text+0x312): undefined reference to `sio_initpar' sndio.c:(.text+0x388): undefined reference to `sio_setpar' sndio.c:(.text+0x3e7): undefined reference to `sio_getpar' libs/openal/libopenal.a(sndio.c.o): In function `sndio_close_playback': sndio.c:(.text+0x61e): undefined reference to `sio_close' libs/openal/libopenal.a(sndio.c.o): In function `sndio_open_playback': sndio.c:(.text+0x6af): undefined reference to `sio_open' ../libs/sdl2/build/.libs/libSDL2.a(SDL_sndioaudio.o): In function `load_sndio_syms': SDL_sndioaudio.c:(.text+0xf): undefined reference to `sio_open' SDL_sndioaudio.c:(.text+0x1b): undefined reference to `sio_close' SDL_sndioaudio.c:(.text+0x27): undefined reference to `sio_setpar' SDL_sndioaudio.c:(.text+0x33): undefined reference to `sio_getpar' SDL_sndioaudio.c:(.text+0x3f): undefined reference to `sio_start' SDL_sndioaudio.c:(.text+0x4b): undefined reference to `sio_stop' SDL_sndioaudio.c:(.text+0x57): undefined reference to `sio_read' SDL_sndioaudio.c:(.text+0x63): undefined reference to `sio_write' SDL_sndioaudio.c:(.text+0x6f): undefined reference to `sio_initpar'

我目前已经安装了这些软件包

libglu1-mesa-dev
libalut0
libalut-dev
libsndio-dev
libroar-dev
libpulse-dev
portaudio19-dev

你知道我遗漏了什么吗？

有两种方法可以解决这个问题

卸载sndio软件包

sudo-apt-remove-libsndio-dev:

添加sndio链接标志

• CMakeLists.txt：在

  目标链接库中添加
  sndio
  ，使其看起来像
  
  目标链接库（SDL2 sndio）

• Makefile：添加

  -lsndio
