    Qt installs to root directories, you need to run it with sudo:
    @
    sudo make install
    @

    As for QtC - either provide that library version, or compile QtC yourself.

    Precompiled package is compiled on Ubuntu. There might be library naming clashes. Compile the stuff yourself or symlink the libraries to cheat the package.

    Either a broken download or some nasty Windows conversion bug, it would seem.

    This should extract the archive. If it fails, check the checksums, maybe your download is bad:
    @
    tar -xaf qt‐everywhere‐opensource‐src‐4.7.0.tar.gz
    @

    I don't think so. RedHat is a big distro, I've never heard people having trouble running Qt there.
