Discovering what library is necessary to run an application

I needed to install rsync in a Solaris 9 so I headed to Sunfreeware and download the package. It had the following description:

Rsync is a replacement for rcp that has many more features – installs in /usr/local. Dependencies: popt, libiconv, libintl, and having libgcc_s.so.1 in /usr/local/lib is required. This can be done by installing libgcc-3.4.6 or gcc-3.4.6 or higher, packages also. There are some new features of version 3 that may require your attention of you have used rsync in the past. See the Details link below for more information.

After you install the package, there is a big probability that it won’t work because it will need the libraries listed in the description. Let’s install and find what my system is missing.

root@solaris9:/tmp/rsync # pkgadd -d rsync-3.0.6-sol9-sparc-local

The following packages are available:

Here I invoke ldd to see what my system is missing. It reported libiconv.so.2, so I need to download the libiconv package as said before.

Invoking ldd again to see if all dependencies are met. Now I need to install libgcc.
