Cannot open shared object file

[bdouble]

Hi there - I am having the exact same behavior as issue #12 - I get the following any time I try to start spopd:

spopd: error while loading shared libraries: libspotify.so.12: cannot open shared object file: No such file or directory

I tried all of the stuff you recommended in the previous thread. I used the method you recommended on 7/29/13, building with the -DCMAKE_INSTALL_RPATH=/usr/local/lib setup.

Here's some system output for you:

root@volumio:# spopd

My one idea as to why this is happening is that libspotify is not the right build for my computer - I'm running this on a Cubox i-4 (Debian Wheezy), which is an ARMv7 Hard Float platform. Libspotify has an ARMv7 build, which seemed to build and install OK, but there is no build for ARMv7hf - and perhaps this is why the system isn't recognizing it. This sort of thing is beyond my technical understanding, though, so I'm just not sure. Hoping you can help!

Oh - you were looking for this info in the thread on #12 :

root@volumio:/usr/local/lib# file /usr/local/lib/libspotify.so.12.1.51
/usr/local/lib/libspotify.so.12.1.51: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, stripped

Hi @bdouble, thanks for this detailed report :)

Could you please try setting LD_LIBRARY_PATH as in #12:

LD_LIBRARY_PATH=/usr/local/lib spopd

If that fails, could you also please run file /usr/local/spopd and uname -mpi?

Thanks!

Hi there - this didn't work, here's the output below.

The system is a Cubox i-4 and I'm running the "Volumio" 1.4 distribution (http://volumio.org/)

root@volumio:/var/www# LD_LIBRARY_PATH=/usr/local/lib spopd
spopd: error while loading shared libraries: libspotify.so.12: cannot open shared object file: No such file or directory

[Schnouki]

Ok, I investigated a bit. Apparently the armv7 version libspotify uses the NEON extensions, which are not available on the CPU of the Cubox i-4.
Could you please try with the armv6 version of libspotify? https://developer.spotify.com/download/libspotify/libspotify-12.1.51-Linux-armv6-release.tar.gz

[bdouble]

Thank you for looking into this! Unfortunately it appears that libspotify just isn't available on my platform. I get the same error. Here's what I did:

I uninstalled the armv7 version (via "make uninstall" as there is a target for this in the libspotify makefile).

Then installed the v6 version in the same place ("make install prefix=/usr/local")

Then re-compiled spopd (deleted the build directory and re-built with the command you gave in #12:

mkdir build && cd build && cmake -DCMAKE_INSTALL_RPATH=/usr/local/lib .. && make && sudo make install

I still get the "Cannot open shared object" error:

root@volumio:/spop/build# spopd
spopd: error while loading shared libraries: libspotify.so.12: cannot open shared object file: No such file or directory
root@volumio:/spop/build# file /usr/local/lib/libspotify.so.12.1.51

[Schnouki]

Hmmm, this doesn't look good. Could you please try with the other ARM releases of libspotify?

[AcidBurns]

Hey,

Same Problem for me here. I tried all (arm) Versions, all failed.

However, I'm using a Raspberry Pi 2 which SHOULD have the NEON extensions (at least according to the raspberrypi forum: https://www.raspberrypi.org/forums/viewtopic.php?f=33&t=100631)
cat /prof/cpuinfo also yields neon extensions:
"Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm"

What did I forget?

uname -mpri gives: 3.18.0-trunk-rpi2 armv7l unknown unknown
I'm running debian testing with some tweaks: http://sjoerd.luon.net/posts/2015/02/debian-jessie-on-rpi2/

Any help appreciated.
