i am installing a client software for a product called vworkspace on CentOS/Suse desktop and it requires a package called popt-devel.

on my centos machine
[root@vworkspace qrdesktop]# rpm -qa | grep popt
popt-1.10.2.3-9.el5

on my suse machine
sled11:~ # rpm -qa | grep popt
popt-1.7-37.8

[code]
[root@vworkspace ~]# cd vworkspaceLinuxClient/qrdesktop/
[root@vworkspace qrdesktop]# ./install.sh

Hello iinfi!

> what is the package popt-devel?

Every package in Linux, mostly rpm packages, follow some naming conventions to make it easier to manage packages. Sometimes software is packaged into two packages, one without -devel and one with -devel. Packages ending in -devel are those that include all the necessary for development for the package (header files, tools used by the software, etc). The other package, the one without -devel, does only include the binaries, manpages and every other files just needed to run the software.

You can read more on this naming convention here:

http://www.rpm.org/max-rpm/ch-rpm-file-format.html

> why is it so difficult to find

Well, once you know how this naming convention goes, just apply it to your search pattern:

popt-devel-1.7-37.8

and you will end up with the correct links.

For SuSE you might try, for example:

In most RPM-based Linux distributions, there are two levels of package management tools.

The "rpm" command is one of the low-level tools: it allows you to manage packages one by one, and requires you to sort out the dependencies manually.

In CentOS, the high-level tool is "yum"; I'm not sure what SuSE uses, but I believe it has something available. The high-level tools will handle the dependencies automatically and usually allow you to configure a set of locations (repositories) for downloading packages automatically.

With these tools, when you specify "install package A", the program might ask "Package A requires packages B and C; the total download size would be XXX kb, OK to download and install them all?"
Using the high-level tools instead of just the "rpm" command will save you a _lot_ of time and sanity in the long run.
