Segfault with Mageia Cauldron (7)

[tbigot]

Since major lib / GCC version update in Mageia Caulton, spotify encounters a segfault at startup.

I do not run cauldron, but for comparison here is output from starting Spotify on Mageia 6 64 bit:

$ spotify

And it runs OK. This is a bit old Spotify version:

$ spotify --version

spotify: /lib64/libcrypto.so.1.0.0: no version information available (required by spotify)

Which Spotify version do you run?

I have no idea if the segfault is a Spotify or Mageia problem, maybe a bit both. You might want to drop in at https://forums.mageia.org/en/viewforum.php?f=15

Maybe there are things in Cauldron that have not been need be rebuilt yet, but need to, (because of gcc and other changes) and will soon get fixed.

[tbigot]

I’m running spotify-client_1.0.59.395.ge6ca9946-18 (the latest available). This was working fine until yesterday. According to the backtrace, the issues is in libssl, maybe libssl / spotify compatibility.

[Morganlej]

OK not my cup of tea. I am an advanced user but not a coder. Regarding the "no version information available" message i found this: https://stackoverflow.com/questions/137773/what-does-the-no-version-information-available-error-from-linux-dynamic-linker

[tbigot]

Yes you’re right, I’ve pasted the no version information available code to be complete, but I know this is normal with spotify-make installation and occurs at each launch, even a successful one. The only relevant part is the last one (segfault) and the backtrace.

[Morganlej]

How did you install Spotify? I wrote this a year ago: https://forums.mageia.org/en/viewtopic.php?f=15&t=11003#p64907 and see that i did not use leamas-spotify at latest installs. In the post above i see that on earlier installs i had problem with earlier Spotify version, and solved that by getting a lib from an earlier Mageia version. Possibly you can work around the current issue in a similar way.

[Morganlej]

I think you should report the problem at the Spotify Linux thread https://community.spotify.com/t5/forums/v3_1/forumtopicpage/board-id/001/thread-id/137071/page/12

[tbigot]

I’ve installed with leamas spotify-make like this:

./configure --prefix=${HOME}/_ --user
make download && make install && make register

I’ll have a look to your link.
