Re: compiling a stand alone ...

[Paul Kienzle]

I wrote a little script to find missing libraries.  Put it
somewhere on your executable path.

E.g.,

pkienzle:Šþ/Mail$ findlib append_history
/lib/libhistory.so.4.1: append_history T 0000421c
/lib/libreadline.so.4.1: append_history T 0001cf5c
/usr/lib/libgnomeui.so.32.11.3: gnome_entry_append_history T 0005b6f0
/usr/lib/libhistory.so.2.1: append_history T 00004e88
/usr/lib/libreadline.so: append_history T 0001cf5c

function searchlib {
    # echo searchlib $file "$2"
    local file flags
    flags="--print-file-name --demangle --extern-only --no-sort ŠÜ
        --portability --defined-only"
    file="$1" ; shift
    [ -z "${file##*.so*}" ] && flags="$flags --dynamic"
    if [ "$file" != "none." ]; then
        # look for pattern [use "2>/dev/null" if nm gives errors]
        nm $flags $file 2>/dev/null | grep "$1"
    fi
}

# search all standard library directories (shouldn't we use ld.conf?)
for dir in /lib /usr/lib /usr/local/lib /usr/X11R6/lib ; do
    # Search only in the newest library/object file: *.a, *.o, *.so*
    # Note: Use ls to get a list of files in alphatical order. That
    # means that the newest .so will be the last name in the list, and 
    # it should be as new as the .a file. So all we have to do is search 
    # the last file before the base name changes.

    # echo Dir=$dir
    last=none.
    for file in `/bin/ls $dir/*.{a,o,so,so.*} 2>/dev/null` ; do 
        # Stemming: chop off the shortest tail matching .a* .o* or .s*
        # Because we are only including .a, .o, .so* patterns in our
        # search, this gets us exactly the base file name.
        # echo "$last, $file->${file%.[aos]*}"
        if [ "${file%.[aos]*}" != "${last%.[aos]*}" ] ; then 
            searchlib $last "$1" ; 
        fi
        last=$file
    done
    # Don't forget the last group!!
    searchlib $last "$1"
done
