Why cannot -libs and -devel be part of the installation on linux?

Why, when installing a new app do we need to also install the -libs and the -devel if the app is needed to make another app work.

Why cannot -libs be part of the installation if they are that important to the operation. Why are -devel, which I'm guessing are development files for the app needed, does this mean the app is bar minimum and cannot be used when required by another app.

Usually packages where the libraries are split out are done that way because they can be shared by other programs, and those programs might not need the whole application. This granularity isn't (usually) strictly necessary, but makes the distribution a lot more flexible. One example would be a split between a graphical interface and the underlying engine -- the engine could be used on a headless server, without needing to pull in the graphical user environment.

If you use the higher level application installer you don't have to worry about this, and even if you use a moderately-low level program like yum, it will pull in all the right packages.

also -devel are only needed when *compiling* other programs, and are not needed at runtime.

you do not need any devel-package if you do not compile software from source if you think so post specific output about what you are talking

they are part of the installation by dependencies

I somehow deleted /tmp when I was deleting files from /tmp to make room. Now I get errors when I boot and try to login

There is a problem with the configuration server.

Installed Fedora 26 on recommendation of a Scribus developer. Installed about 30 packages per his advice.

But when I try to compile a program the machine can't find C++. So what is the package I need to install to compile C++ programs?.

Another question. On Slackware (yes I am one of those) I can use kdm to get to a window function ( I preferXFCE). How do I set up a window manager in Fedora and how do I access it?

In order to do an OS install, you need to have an external media to start the install process. This media provides a "base"/small system that you can then use to do a larger netinstall, or a larger update process to get the drive/system setup the way you want. All of the larger system install data/packages/etc can come from the http/net install process.

In most (all) cases I've seen, the process is then to take/remove the CD from the system, followed by a restart, where the system OS on the drive then gets invoked.

So this process requires some manual interaction.

Here's my question:
Is there a way to do the same basic process, except to always leave the CD in, and to then be able to "switch" the system, so it "knows" which media to install from.

If this can be done, one can setup a system with a basic cd that will, when run, create/start the basic OS install, but then not be used any other time... This could allow for an auto/programatic approach to be able to do a remote/auto OS install.

Is there any other way that this might be accomplished?
