How do you know where a package would by install. Is it always installed in usr/local/? Does it matter or not where i place it?

Where should a package install???
Thats the 64$ question...there are as many opinions where things should install to as there are places to install to, in redhat and mandrake kde and gnome are installed to /usr/local but in slack they go in /opt. Needless to say /opt is the correct place for things like GUI's and /usr is correct for programs that are installed for the users to use.....but often it depends on the opinion of the person who wrote the code/made the package as to where it installs to. With an rpm based distro its almost always /usr.
(Flames to /dev/null please)

Do you have to recompile after and installation of a package?
and what does it involve doing?
thxs

not sure what you mean recompile after package.. the kernel ?? ah no.. once package is installed you don't have to do anything but either run the program or configure it then run it..

If so,
why if i have a program that requires a dependency. I download and install the required package, and after, it still ask for the same stuff?

usually in the readme and install files it will say what all the program needs for dependancies.... that is the first place i look before installing, so i can install those before the program.

thx

Again if a dependency is required, ( like my Mysql-DBI-perl-bin stuff) when i made a serch on the net to find it, i find some with the same name but no one on the red hat site... since i am installing on a redhat7,2 machine would a package from somewere else do the trick? Like this one: http://cable.linuxppc.org:8080/softw...-perl-bin.html

yeah, it should. redhat won't have every package on their site required by other software means.

It sounds like you are having a problem with libraries, not sure.

what is the error?

libraries installed by programs that are required by other programs need to be linked into the library path, or their path must be added to ld.so.config.
