I'm trying to install header files for the X libraries on my DSL system so that I can compile some of my own packages from source, but before I can run apt-get to get the "devel" packages, I need to know *which* devel packages to get. So I would like to see the list of currently installed package names. How does one do this on DSL?

Thanks,
Dave

If you type

dpkg -l

in a xterm it will print a list of installed packages. Alternatively you could use a frontend to apt like synaptic to see a list of installed packages (you can install this from the DSL menu). Not all the software in DSL is the form of Debian packages so not everything will show up (e.g. firefox won't appear in the list), but I imagine most libraries will.
