That's a bit peculiar. When I install a build into /dev/shm/test … I
get this bit:

libtool: install: /usr/bin/install -c src/libsyn123/.libs/libsyn123.so.0.1.0 /dev/shm/test/lib/libsyn123.so.0.1.0
libtool: install: (cd /dev/shm/test/lib && { ln -s -f libsyn123.so.0.1.0 libsyn123.so.0 || { rm -f libsyn123.so.0 && ln -s libsyn123.so.0.1.0 libsyn123.so.0; }; })
libtool: install: (cd /dev/shm/test/lib && { ln -s -f libsyn123.so.0.1.0 libsyn123.so || { rm -f libsyn123.so && ln -s libsyn123.so.0.1.0 libsyn123.so; }; })
libtool: install: /usr/bin/install -c src/libsyn123/.libs/libsyn123.lai /dev/shm/test/lib/libsyn123.la
libtool: finish: PATH="/media/thomas/handtasche/thomas/bin:/home/thomas/bin:/home/thomas/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/sbin" ldconfig -n /dev/shm/test/lib
----------------------------------------------------------------------

It installs libsyn123.so.0.1.0 and calls ldconfig on the directory,
also creating those symlinks mpg123 needs:

$ldd /dev/shm/test/bin/mpg123
	linux-vdso.so.1 (0x00007fffb017b000)
	libmpg123.so.0 => /dev/shm/test/lib/libmpg123.so.0 (0x00007efc2d3e8000)
	libout123.so.0 => /dev/shm/test/lib/libout123.so.0 (0x00007efc2d1d8000)
	libsyn123.so.0 => /dev/shm/test/lib/libsyn123.so.0 (0x00007efc2cf8c000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007efc2cbee000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007efc2c7fd000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007efc2c5f9000)
	/lib64/ld-linux-x86-64.so.2 (0x00007efc2d874000)

I wonder if there's anything wrong if the install process … do you
actually miss the libsyn123.so.0 name (but have the others)
in /usr/local/lib (or the actual lib subdir if you have a multiarch
system) before running ldconfig yourself?


Alrighty then,

Thomas
