revdep-rebuild = find broken libs

this is a Ligth version of revdep-rebuild script used on gentoo systems (no portage finding packages for missing libs). It can find missing  libs like

 broken /opt/kde/lib/kde3/kio_smb.so (requires  libsmbclient.so.0)
  broken /opt/kde/lib/kde3/kio_svn.so (requires  libneon.so.24 libsvn_client-1.so.0 libsvn_delta-1.so.0 libsvn_diff-1.so.0 libsvn_fs-1.so.0 libsvn_fs_base-1.so.0 libsvn_fs_fs-1.so.0 libsvn_ra-1.so.0 libsvn_ra_dav-1.so.0 libsvn_ra_local-1.so.0 libsvn_ra_svn-1.so.0 libsvn_repos-1.so.0 libsvn_subr-1.so.0 libsvn_wc-1.so.0)
  broken /usr/lib/libdivxencore.so (requires  libstdc++-libc6.2-2.so.3)
  broken /usr/lib/libpq++.so.4.0 (requires  libpq.so.3)
  broken /usr/lib/php/odbc.so (requires  libodbc.so.1)
  broken /usr/lib/tuxcmd/libgnome_vfs.so (requires  libORBit-2.so.0 libbonobo-2.so.0 libbonobo-activation.so.4 libgconf-2.so.4 libgnomevfs-2.so.0)
  broken /usr/lib/xine/plugins/1.0.1/xineplug_inp_smb.so (requires  libsmbclient.so.0)

it found arch "optional" dependencies smile could be usefull when making packages with unknown dependencies etc.

save as, make it executable and then run it as root smile (get the code via "quote" - phpBB may damage the script tongue)

Re: revdep-rebuild = find broken libs

I've taken revdep-rebuild and converted it for Arch & Pacman, as findbrokenpkgs.

It highlights libgphoto2 2.4.0-5 as broken, because of this line in the libgphoto2 pkgbuild:

rm -f ${startdir}/pkg/usr/lib/*.la

I'm very tempted to raise that as a bug in the libgphoto2 pkgbuild - any feedback? smile

Re: revdep-rebuild = find broken libs

OK, I've updated findbrokenpkgs with LC_ALL=C - seems to work on my little test, after I set:

$ export | grep UTF
declare -x LANG="de_BE.UTF-8"
declare -x LC_ALL="de_BE.UTF-8"

Please grab version 0.2 from AUR wink

Re: revdep-rebuild = find broken libs

Take a look at /usr/bin/findbrokenpkgs - dynamic library files which are expected to exist because they are *needed* by an executable/library, are missing. This can usually be fixed simply by recompiling the affected packages, to point them at the library files which *do* exist.

Dunno how Arch Linux has existed without such a checker, because such breakage occurs often, when libraries increment their soname. revdep-rebuild is an essential program in Gentoo. Binary distro users are spoiled rotten by having the recompilations done for them wink

Example:

ldd /usr/lib/libalpm.so
objdump -p /usr/lib/libalpm.so

not quite..its to have look at the consistincy of the system...for example i also had alsa-plugins from arch official repo..and it reported me as broken....

Interesting. lddd raises the following warning, which seems to be a false alarm:

$ ldd /usr/lib/xulrunner-1.8.1.12/libgtkembedmoz.so | grep xpcom
    libxpcom.so => not found

$ objdump -x /usr/lib/xulrunner-1.8.1.12/libgtkembedmoz.so | grep NEEDED | grep xp
  NEEDED      libxpcom.so
  
$ find /usr/lib -name libxpcom\*
/usr/lib/xulrunner-1.8.1.12/libxpcom.so

findbrokenpkgs treats this dependency as *found* rather than missing, because of its long colon-delimited $COMPLETE_LD_LIBRARY_PATH, which includes:

Re: revdep-rebuild = find broken libs

I've reported libgphoto2, to grab attention and hopefully fix the exception smile

Re: revdep-rebuild = find broken libs

I think there should be some warning for people that don't quite understand what's going on, that it's OK for some packages to be reported as "broken", like amarok-base, flac, gnumeric, php, vlc, xine-lib, ... since they are compiled with optional support of some stuff *if* the correct libs are present. If they are not, then the programs still run fine, except they refer to libs which are not present.

Re: revdep-rebuild = find broken libs

it keeps teeling me audacious-plugins needs to be recompiled..and i already did it tongue
/usr/lib/audacious/Input/amidi-plug/ap-fluidsynth.so needs missing libfluidsynth.so.1
  /usr/lib/audacious/Visualization/projectm.so needs missing libprojectM.so.0


Its a sick world we live in....

Use the ldd and objdump commands to see for yourself easily, as I mentioned above.

$ find /usr/lib -name libfluid\*
/usr/lib/libfluidsynth.so.1
/usr/lib/libfluidsynth.so.1.1.2
/usr/lib/libfluidsynth.so
/usr/lib/libfluidsynth.a

Here's my /usr/local/sbin/compilepkg so people can see what "recompile the package" means - run it from within /var/abs/local/pkgname/

#!/bin/bash

# Posted at http://bbs.archlinux.org/viewtopic.php?pid=347363#p347363

if [[ -n ${1} ]] ; then
    pkgname=${1}
else
    pkgname=$(basename ${PWD})
fi

# Fix for tedious permissions problems
cd /var/abs/local/ && chown root:root * && chmod -s *

cd /var/abs/local/${pkgname}/ || exit 1
# Sets gnome-terminal title
echo -n -e "\e]0;make ${pkgname}\a"
rm -rf src pkg && chown root:root * && chmod -s * && makepkg -fi --asroot
if [ $? -gt 0 ] ; then
    # Reset gnome-terminal title
    echo -n -e "\e]0;${pkgname} failed\a"
    exit 1
fi

# Find the correct pkg to check
f=$(ls -t *.pkg.tar.gz | head -n 1)
[[ -n ${f} ]] && namcap ${f}
namcap PKGBUILD

# Check .desktop files, if any
# http://freedesktop.org/wiki/Specifications/desktop-entry-spec
fl=$(ls -t *.desktop 2>/dev/null | head -n 1)
for f in $fl ; do
    desktop-file-validate --warn-kde ${f}
done

# Reset gnome-terminal title
echo -n -e "\e]0;Terminal\a"

Edit:  Added 2 echos, to set & reset the gnome-terminal title.

That's right, I got quite a few outputs but there were all normals. People have to figure that themselves, this is more a dev tool anyway (at least on a binary distrib)

Yea, but you know... once it's on the forum, there *will* be more people trying it and wasting watts on recompiling smile

I'll just add a link to this thread. The program cannot be expected to explain the subtleties of optional vs needed dynamic library linking. What would it say? "This could be right, or it could be wrong. Whaddyawannado?" wink

AFAICT, there's no way for the program to distinguish between "needed" and "optional" dependencies. If anyone knows a way, I'd love to hear it. So, it can only report the problems it sees.

The thing is, every distro screws up occasionally, and one of the ways they screw up is with the dependencies that this tool checks. Which makes this a useful tool. What's the usual response from the Arch devs? Use abs and compile yourself. And if you're using Testing/Unstable, or not doing a full update every time, you're on your own. They use that response, because it's the correct response. Individual users should be having some responsibility over their "linking". Users wouldn't last a month in Gentoo without such a responsibility.

Arch isn't a binary distro, it's a core of binary packages with lots of do-it-yourself packages in the AUR. I reckon that's the reality, for the sort of people who would be using/attracted to this distro. I mean, who on Earth wants crappy fonts when they can compile cairo-ubuntu? (shameless plug)
