Discover library dependencies on Slackware

Posted 05-28-2009 at 03:34 AM by gabim

I created a script to discover the library dependencies on my system:
Code:
#!/bin/bash

ECHO=/usr/bin/echo
SED=/usr/bin/sed
FILE=/usr/bin/file
CUT=/usr/bin/cut
LDD=/usr/bin/ldd
GREP=/usr/bin/grep
AWK=/usr/bin/awk

for p in `$ECHO $PATH | $SED 's/:/ /g'`
do
    for f in $p/*
    do
        if [ 'ELF' == `$FILE -b $f | $CUT -d' ' -f1` ]; then
            if $LDD $f | $GREP -q 'not found'; then
                $ECHO "$f"
                $LDD $f | $GREP 'not found' | $AWK '{print "Not found:", $1}'
            fi
        fi
    done
done
I found some missing libraries by this (and searched the missing packages from MANIFEST.gz) and maybe this script can be useful for others also.

    This was REAL helpful!!

    Thanks for writing this. I hope you don't mind. I copied this into a bash script and modified the output to a file instead. I can then check each entry of the file against the MANIFEST.gz, and grap the dependencies as required.

    Thanks,
    Shingoshi

    You are welcome! I'm happy to help by this little script.

    New version

    The new version prints the missing package names instead of the missing library names, so one have to install only the given packages mentioned by this script.
    Code:
    root@slack64:~# cat /usr/local/bin/sldd                                 
    #!/bin/bash                                                             
    # file: sldd

    # This is the concatenated MANIFEST file of slackpkg on Slackware64

    # Check all directories in PATH
    for directory in `$ECHO $PATH | $SED 's/:/ /g'`
    do
        # Check all binaries in PATH directories
        for binary in $directory/*
        do
            # If it is true ELF binary
            if [ 'ELF' == `$FILE -b $binary | $CUT -d' ' -f1` ]; then
                # Show the progress by printing of actual filename on standard error
                $PRINTF "%-70s\r" $binary >&2
                # Check the missing shared library dependencies
                $LDD $binary 2>$NULL | $GREP 'not found' | $AWK '{print $1}' | while read missing_lib
                do
                    # Print the package name of the missing library
                    $ZGREP $missing_lib $MANIFEST | $AWK '{print $1}'
                done
            fi
        done
        # Clear the progress info
        $PRINTF "%-80s\r" "" >&2
    # Ignore the duplicated package names
    done | $SORT -u
    The time of running is relatively long, it takes about 4.5 mins at me.

    You have inspired me to do the same thing. To post small scripts that I've written in my blog also. In fact, you have yourself to blame (I think) for my becoming aware that there even was the possibility to have a blog.

    So for all the time I sit on my @$$ writing scripts, I might as well start sharing them.

    Yes, we can start to share our small scripts, the Slackware will be better by this.
    I started the sharing by a next step, see on http://slackwiki.org/Dependency_Discovery . I hope it will help more people than here.
