linux installs

i'm fairly new to linux... there are a few things i'd like to install on my RHEL 7.3.
GNS3, ClamAV, and Snort, and world community grid

yum doesn't cover either of these programs, or there is a dependency missing

for example, i need libpcre.so.0()(64bit) for one of these programs, and when i look it up on the internet, a rpm database comes up and i can download it and install it, but it fails, so where can i get a functional working copy of this dependency?  i've tried yum provides and it does not find it.

is this just RHEL? should i try debian?  many of these software packages seem to advertise support of debian, fedora, or ubuntu -- not so much RHEL

can anyone provide some insight into installing and compiling tar.gz files?  i installed the C compiler gcc so i could use the ./configure command, but i try to 'make' the install and i'm not quite familiar with the context to use the make command in.

should untar'ing and installing be the goto solution when your installer (i.e. yum or apt-get) do not have the package?  should i untar the file into the /bin directory?  

thanks in advance for any help

PCRE is Perl Compatible Regular Expressions.  I would expect it to already be installed, actually.

Red Hat is OK but I find debian easier to work with.  It has a large support base and more people using it.  Or you could try Ubuntu, which is debian simplified for folks who use the KDE or Gnome graphical interfaces rather than hard-core traditional command line.

(Under debian, the command to fix the PCRE problem would be:  apt-get install libpcre3 libpcre3-dev)

Choose well when choosing a linux distribution, because whatever you choose is probably what you'll be using for the rest of your career.

Welcome to the world of Linux!

What is your main goal for switching to Linux? Are you switching?

You want to run snort to do what? It runs on Windows as well.

Choosing a Linux distribution can be a challenge, just have a look at Distrowatch on how many there are. Starting with a 'basic' one to learn and get a bit experienced is what I would do.

So did you manage to get that missing library? Which repo did you use to resolve your issue?
I think red hat base repo got pcre-devel ;)
