I am trying to run the spotify examples. I have sucecsfully compiled them but I cannot run anything. When i.e. do ./jukebox.o it just says "cannot execute binary file". How do I run the examples?

This is what I got when i did make:

libspotify/examples$ make LIBSPOTIFY_PATH=../../../.. for a in jukebox spshell localfiles; do make -C $a LIBSPOTIFY_PATH="/home/alexander/slask/libspotify-12.1.51-Linux-x86_64-release" all; done make[1]: Entering directory /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' make[1]: Entering directory /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' make[1]: Entering directory /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'

  • What operating system are you using, and how did you go about building the examples? "jukebox.o" sounds like an object file, not an executable, so it's possible you've compiled it but not linked it. – Weeble Feb 25 '14 at 22:53
  • I compiled it using the Makefile. Running Ubuntu 64bit. – AlexanderNajafi Feb 26 '14 at 07:03

I had a similar problem on 64-Bit Ubuntu. Edit the LDLIBS line in examples/common.mk to read as follows

LDLIBS  += -lspotify -lpthread -ldl

You have to make the file executable.

Try chmod u+x jukebox.o and if that doesn't work, you should try compiling it like gcc jukebox.c -o jukebox

On Linux, after you've successfully run the makefile, your share/doc/libspotify/examples/jukebox directory should look like this:

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

The executable file is the one called "jukebox". So run "./jukebox/jukebox". If that file isn't there, perhaps the build process failed. Were there any messages or warnings when you ran "make"?
