运行libspotify示例

Question

我正在尝试运行spotify示例。我已经成功地编译了它们，但是我不能运行任何东西。如果是do./jukebox.o，它只会说“无法执行二进制文件”。如何运行这些示例？

这是我在做的时候得到的：

libspotify/examples$ make LIBSPOTIFY_PATH=../..对于光盘机中的spshell本地文件，请务必使LIBSPOTIFY_PATH="/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release“-C $a all；完成make1:进入目录/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/share/doc/libspotify/examples/spshell' cc -I/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/include -Wall -Wl,-rpath,/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/lib -L/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/lib spshell.o spshell_posix.o appkey.o cmd.o browse.o search.o toplist.o inbox.o star.o playlist.o test.o -lreadline -lspotify -o spshell /usr/bin/ld: spshell_posix.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5' /lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[1]: *** [spshell] Error 1 make[1]: Leaving directory/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/share/doc/libspotify/examples/spshell‘make1:进入目录/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/share/doc/libspotify/examples/jukebox' cc -I/usr/include/alsa -I/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/include -Wall -Wl,-rpath,/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/lib -L/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/lib jukebox.o appkey.o alsa-audio.o audio.o -o jukebox -lasound -lspotify /usr/bin/ld: alsa-audio.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5' /lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[1]: *** [jukebox] Error 1 make[1]: Leaving directory/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/share/doc/libspotify/examples/jukebox’make1:进入目录/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/share/doc/libspotify/examples/localfiles' make[1]: Leaving directory/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release/share/doc/libspotify/examples/localfiles‘

Answer 1

我在64位的Ubuntu上也遇到了类似的问题。编辑examples/common.mk中的LDLIBS行，如下所示

LDLIBS  += -lspotify -lpthread -ldl

Answer 2

您必须使文件成为可执行文件。

试试chmod u+x jukebox.o，如果不起作用，你应该试着像编译gcc那样编译它。c -o jukebox

Answer 3

在Linux上，成功运行makefile后，您的share/doc/libspotify/examples/jukebox目录应该如下所示：

weeble@mylaptop:~/prj/libspotify/libspotify-12.1.51-Linux-i686-release/share/doc/libspotify/examples$ ls -l jukebox/

可执行文件是名为"jukebox“的文件。所以运行"./jukebox/jukebox“。如果该文件不在那里，则可能构建过程失败。当你运行"make“的时候有没有什么消息或者警告？
