Slackware64-current - missing libnettle.so.6

[MikeTatsuo]

1. Slackware64-current
2. Free
3. 1.0.89
4. Spotify doesn't start, and on the console give me the error 

   /opt/spotify/usr/bin/spotify: error while loading shared libraries: libnettle.so.6: cannot open shared object file: No such file or directory

The current version of the package is 1:1.1.5.153.gf614956d-16 - have you tried updating?

Have you tried installing/updating nettle package?

Just saying...

UPDATE: I managed to solve the issue, thanks to Giacomo (https://github.com/jak3)

The Spotify in the sbopkg for Slackware-current has the file /opt/spotify/usr/lib/libcurl-gnutls.so.4 linked to libcurl-gnutls.so.4.5.0 in the same folder, so Giacomo suggested to create a symlink libcurl-gnutls.so.4 to /usr/lib64/libcurl.so, so I renamed the libcurl-gnutls.so.4 to libcurl-gnutls.so.4.bkp

mv /opt/spotify/usr/lib/libcurl-gnutls.so.4 /opt/spotify/usr/lib/libcurl-gnutls.so.4.bkp

and created a symlink to /usr/lib64/libcurl.so

ln -sf /usr/lib64/libcurl.so /opt/spotify/usr/lib/libcurl-gnutls.so.4

and worked 😄

Because the Spotify is built for Ubuntu, it has some libraries which don't exist in the Slackware, so the latest version working, installing by sbopkg is what have.

I already have the latest nettle, the issue is because the Spotify is looking for an old version, and I don't think downgrading is an acceptable solution.

Slackware64-current uses nettle 3.5.1 (libnettle.so.7.0) so making a symlink to the system /usr/lib64/libcurl.so.4.5.0 seems to work.

Another option is to rebuild curl without SSL but with GNUTLS. Uncomment/and add the following lines in the curl.Slackbuild-script:

# Uncomment to build a no-SSL version:
SSLOPT=--without-ssl
./configure \
--prefix=/usr \
 --libdir=/usr/lib${LIBDIRSUFFIX} \
 --mandir=/usr/man \
 --with-ca-bundle=/usr/share/curl/ca-bundle.crt \
 --with-libssh2 \
 --with-gnutls \
 --enable-static=no \
 $SSLOPT || exit 1

Place the resulting libcurl.so.4.5.0 in your Spotify installation directory. Rename as libcurl-gnutls.so.4 and you are good to go. Keep in mind that you will need to rebuild this every time nettle is upgraded since libcurl is bulit against nettle.
