Hmm, not sure about AIX, but for most Linux libraries you usually have a "config" script for each library you can call to get the library version.

For example, on my machine, I can do this

[rylan@development ~]$ sdl-config --version
[rylan@development ~]$
in a terminal. This tells me that I have the 1.2.10 version of the SDL library on my system.

I. e. try doing

# dec2-config --version

# libdec2-config --version

# dec-config --version
in a terminal on your AIX system and see if you get any joy.

Question Thanx a ton rylan76...for your reply

I tried the solution provided by you but I am not able to do find the version information.Actually my product uses third party component for example Verity and Decomposer and I want to find out the version information of these third party component. I check my system but I was not able to find "config" script and that why I m getting "command not found" error when I tried any of the solution provided by you.So Is there has any other way to find out the same ??

You can view the filesets with lslpp -l and files within a fileset with lslpp -f <fileset>.

You can list the content of the file:
ar -X32_64 tv /path/libdec2.a
Also you can check if this file belongs to some package:
lslpp -w /path/libdec2.a
rpm -qf /path/libdec2.a

The following shows all .a files along with their fileset/level
lslpp -f | awk '$1~/^[^\/]+$/ && $2~/^[0-9.]+$/ {fs=$1;ver=$2} $NF~/\.a$/ {print $NF, " --> "fs,ver}'

Hi MadeInGermany,

Interesting "one-liner". However, the fileset numbering is not always the libary version. e.g., several "standard libaries" are part of rpm.rte - and that is not the "version" number I would be expecting.


aixtools@x071.home.local:[/usr/lib]$NF~/\.a$/ {print $NF, " --> "fs,ver}' | grep intl                        <
/opt/lib/libintl.a  --> aixtools.gnu.gettext.rte
/usr/opt/freeware/lib/libintl.a  --> rpm.rte

aixtools@x071.home.local:[/usr/lib]{print $NF, " --> "fs,ver}' | grep libz                                   <
/usr/java5/jre/bin/libzip.a  --> Java5.sdk
/usr/java5_64/jre/bin/libzip.a  --> Java5_64.sdk
/opt/lib/libz.a  --> aixtools.zlib.rte
/usr/opt/freeware/lib/libz.a  --> rpm.rte
Inside the archives - it can be quite difficult. The legacy name of the "shared-library" member in AIX archives is "shr.o", e.g.,

aixtools@x071.home.local:[/usr/lib]ar tv /usr/ccs/lib/libdecNumber.a
r--r--r--     2/2     107533 Dec 10 03:28 2015 shr.o
So, when I have been packaging (and, luckily, the default naming in most autotool generated Makefiles) the members look like:

aixtools@x071.home.local:[/usr/lib]ar tv /opt/lib/libz.a

rw-r--r--     0/0      10385 Jan 31 12:55 2017 gzwrite.o
Compare that with:
aixtools@x071.home.local:[/usr/lib]ar tv /opt/freeware/lib/libz.a
rwxr-xr-x   203/1     120624 Jan 03 16:59 2008
rwxr-xr-x   203/1       6015 Jan 03 16:59 2008 shr.o
For the later - when I wrote programs to determine what version of libz was provided I got, initially version 1.2.4 and later 1.2.8. FYI I am providing all the different versions so that programs linked to older versions of 1.2.X will still find there old version. In the case of libz (aka zlib) it is better practice to specify

For the curious: the .o members are static routines that can be linked into a program rather than use the RTLD (Run-Time LoaDer).
