[CentOS] libqt4-qt3support Dependency Hell

Please Read the information concerning "Guidelines for CentOS Mailing
List posts" at the bottom of this link:

http://www.centos.org/modules/tinycontent/index.php?id=16

Specifically, it is much easier to follow a quoted e-mail on the list if
you do not "top post".

It is also better to set your e-mail client to send to the list as
"Text" and not "HTML" type.

With respect to installing RPMS ...

You CAN NOT install rpms built for one distribution on another
distribution ... let me explain why.

Linux uses "Shared Libraries" (as does Windows with .dll files).  The
point of a "Shared Library" is so that you only build the NEW things you
need for the program you are building, and you get the REST of the
information from files that are already available.

If you try to install packages built against Fedora 11 on CentOS 5 then
none of the "Shared Libraries" that the package was built against (the
versions in Fedora 11) are in CentOS 5, so it does not work.

It is sometimes possible to take Fedora "SOURCE RPMS" (a
<package_info>.src.rpm) and build it on a CentOS 5 machine and then use
the resultant "Binary RPMS" on CentOS-5.

One should NEVER, EVER install "Binary RPMS" from one distribution on
another distribution ... doing will not work. The files are built
against different libraries and even if they install they will likely
not work.

As others have pointed out, there are other repositories available:

http://wiki.centos.org/AdditionalResources/Repositories

If what you need is not there, you will need to build it or convince
someone else to build it for you.

Thanks,
Johnny Hughes
