  • Where does the ELF binary dynamic library name come from?

    From Don@21:1/5 to All on Tue Mar 2 04:10:38 2021
    Greetings,

    These arguments (and others) are used with libtool:

    -I/usr/local/include/guile/2.2 -L/usr/local/lib -lguile-2.2

    yet readelf reveals:

    # readelf -d /usr/local/bin/gschem | grep guile
    0x0000000000000001 NEEDED Shared library: [libguile-2.0.so.22]

    when it ought to point to:

    libguile-2.2.so.1

    Where does the ELF binary dynamic library name come from?


    Further details of the back story are available at:

    Danke,

    $ objdump -p /usr/lib/x86_64-linux-gnu/libX11.so.6 | grep SONAME
    SONAME libX11.so.6

    (I do not have libguile installed.)

    That's something which can only be guessed at with this level of
    information. A possible scenario could be: Something linking with a
    static version of libguile-2.2 also links with a dynamic libray linked
    with libguile 2.0.

    Coming to think of it: This can't have happened as the library would
    then be recorded in the dynamic section of the library.
