Running ldconfig was the first I did, but you're right, I missed that
/usr/local/lib64 wasn't added to the configuration, resp. I should have
added a link, because for 64 Studio/ Ubuntu the 64bit libs are in
/usr/local/lib, resp. /usr/lib.

OT for this problem: However there seems to be a bug for the configure
or make file, because jconvolver wants libzita-convolver.so.2, but after
compiling and installing there were only
/usr/local/lib64/libzita-convolver.so -> libzita-convolver.so.2.0.0 and
libzita-convolver.so.2.0.0, thus even if I wouldn't have made this
mistake, a link /any/used/lib_path/libzita-convolver.so.2.0.0 ->
/any/used/lib_path/libzita-convolver.so.2 is missing and needs to be added.

spinymouse-sudo@email-addr-hidden:/etc/ld.so.conf.d$ ls
kde4.conf libc.conf x86_64-linux-gnu.conf
spinymouse-sudo@email-addr-hidden:/etc/ld.so.conf.d$ cat libc.conf
# libc default configuration
/usr/local/lib
spinymouse-sudo@email-addr-hidden:/etc/ld.so.conf.d$ cat x86_64-linux-gnu.conf
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
spinymouse-sudo@email-addr-hidden:/etc/ld.so.conf.d$ cat kde4.conf
/usr/lib/kde4/lib

Hm, /usr/lib, /usr/lib32 will be found by default? /usr/lib64 -> lib is
a link.

Anyway, I fixed it now:

spinymouse-sudo@email-addr-hidden:/usr/local/lib64$ ls
libzita-convolver.so libzita-convolver.so.2.0.0
spinymouse-sudo@email-addr-hidden:/usr/local/lib64$ sudo mv * /usr/local/lib
spinymouse-sudo@email-addr-hidden:/usr/local/lib64$ cd ..
spinymouse-sudo@email-addr-hidden:/usr/local$ sudo mv
/usr/lib/libzita-convolver.so.2 /usr/local/lib
spinymouse-sudo@email-addr-hidden:/usr/local$ sudo rm -r lib64
spinymouse-sudo@email-addr-hidden:/usr/local$ sudo ln -s /usr/local/lib
/usr/local/lib64
spinymouse-sudo@email-addr-hidden:/usr/local$ sudo ldconfig
spinymouse-sudo@email-addr-hidden:/usr/local$ jconvolver -h

Jconvolver 0.8.4
(C) 2006-2009 Fons Adriaensen <fons@email-addr-hidden>

Usage: jconvolver <options> <config file> {<connect file>}
Options:
  -h Display this text
  -v Print partition list to stdout [off]
  -L <nframes> Try to compensate <nframes> latency
  -M Use the FFTW_MEASURE option [off]
  -N <name> Name to use as JACK client [jconvolver]

Thank you :).

Ralf
