I'm using Linux Slackware 8.1 kernel 2.4.18 . I have tried to install Qt but it is failed. This is a part of the errors:

make[2]: [install_docs] Error 1 (ignored)
cp -f -p "../doc/html/layout-example.html" "/usr/local/qt/doc/html/"
cp: `../doc/html/layout-example.html' and `/usr/local/qt/doc/html/layout-example.html' are the same file
make[2]: [install_docs] Error 1 (ignored)
cp -f -p "../doc/html/layout.html" "/usr/local/qt/doc/html/"
cp: `../doc/html/layout.html' and `/usr/local/qt/doc/html/layout.html' are the same file
make[2]: [install_docs] Error 1 (ignored)
cp -f -p "../doc/html/layout1.png" "/usr/local/qt/doc/html/"
cp: `../doc/html/layout1.png' and `/usr/local/qt/doc/html/layout1.png' are the same file
make[2]: [install_docs] Error 1 (ignored)
strip "/usr/local/qt/doc/html/"
strip: /usr/local/qt/doc/html/: Is a directory
make[2]: *** [install_docs] Error 1
make[2]: Leaving directory `/usr/local/qt/src'
make[1]: *** [src-install] Error 2
make[1]: Leaving directory `/usr/local/qt'
make: *** [install] Error 2

I don't understand why it was the same file and why it can't just overwrite the existence files. I hope someone can help me and i apologize if my english is hard to understand.

Assuming that the files are actually ok, I'd bet on a permissions issue.
Typically, you will want to do everything (download, untar, configure, make) as a user (not root) up until the "make install" for which you most likely _do_ want to be root. But, that said, I haven't tried to build Qt, so I may be off base.

When I installed my Nvidia Card I used this Mini How-To. There was a section on installing QT. I installed but know anything that uses KDE won't work but it installed

Mini-HowTo

Ok thanx. It is installed now.

Just curious if your able to run any kde apps or even start kde. I keep getting an error about cannot understand or load some library with qt.
