how to know which package uses a library?

acidjuice · 05-13-2005, 10:25 AM

dear all,

i'm into /var/log/packages and am searching to find which package(s) use a particular library. is there a way to do so without cat every single file and see if in its list the library is shown?

thank you...

aj.

I think you can find what libraries a program uses by using ldd. Say for xmms,

Code:

ldd /usr/bin/xmms

would give out

Code:

        linux-gate.so.1 =>  (0xffffe000)
        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40029000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40032000)
        libXxf86vm.so.1 => /usr/X11R6/lib/libXxf86vm.so.1 (0x4004a000)
        libxmms.so.1 => /usr/lib/libxmms.so.1 (0x4004f000)
        libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0x4005c000)
        libgdk-1.2.so.0 => /usr/lib/libgdk-1.2.so.0 (0x4017a000)
        libgmodule-1.2.so.0 => /usr/lib/libgmodule-1.2.so.0 (0x401ab000)
        libgthread-1.2.so.0 => /usr/lib/libgthread-1.2.so.0 (0x401af000)
        libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x401b2000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x401d3000)
        libdl.so.2 => /lib/libdl.so.2 (0x40225000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40229000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40237000)
        libm.so.6 => /lib/libm.so.6 (0x40302000)
        libc.so.6 => /lib/libc.so.6 (0x40325000)
        /lib/ld-linux.so.2 (0x40000000)

EDIT: Hmm, and i just noticed you want the opposite of that...

grep libblah /var/log/packages/*

?

But that will tell you what packages include the given library, not use it. Which is perhaps not what you want?

i get:

Code:

/usr/lib64# grep libglib-2.0* /var/log/packages/*
Binary file libglib-2.0.so.0.600.0 matches
/var/log/packages/aaa_elflibs-1.0.0-x86_64-1:usr/lib64/libglib-2.0.so.0.600.0

if this means that only aaa_elflibs contains the libglib2 then this is exactly what i needed

Do no add a '*' in the grep pattern or quote it with ' ' if you need it

In your case, the shell expanded the * to all files in current dir, so
grep found a file which was on the current dir when you run this
command

There should not be binary files in /var/log/packages
