Installing qt

[ral]

I grabbed the free version. These are instructions I found:

 

"INSTALLING Qt FOR X11

 

You may need to be logged in as root, depending on the permissions of

the directories where you choose to install Qt.

 

 

1. Unpack the archive if you have not done so already:

 

cd /usr/local

gunzip qt-x11-3.0.6.tar.gz # uncompress the archive

tar xf qt-x11-3.0.6.tar # unpack it

 

This creates the directory /usr/local/qt-3.0.6 containing the

files from the main archive.

 

Rename qt-3.0.6 to qt (or make a symlink):

 

mv qt-3.0.6 qt

 

The rest of this file assumes that Qt is installed in /usr/local/qt."

 

I manage to get everything right until here, but I am kind of lost in the next part. Help :(

 

 

"2. Set some environment variables in the file .profile (or .login,

depending on your shell) in your home directory. Create the

file if it is not there already.

 

QTDIR - the directory in which you're building Qt

PATH - to locate the moc program and other Qt tools

MANPATH - to access the Qt man pages

LD_LIBRARY_PATH - for the shared Qt library

 

This is done like this:

 

In .profile (if your shell is bash, ksh, zsh or sh), add the

following lines:

 

QTDIR=/usr/local/qt

PATH=$QTDIR/bin:$PATH

MANPATH=$QTDIR/doc/man:$MANPATH

LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

 

export QTDIR PATH MANPATH LD_LIBRARY_PATH

 

In .login (in case your shell is csh or tcsh), add the following lines:

 

setenv QTDIR /usr/local/qt

setenv PATH $QTDIR/bin:$PATH

setenv MANPATH $QTDIR/doc/man:$MANPATH

setenv LD_LIBRARY_PATH $QTDIR/lib:$LD_LIBRARY_PATH

 

After you have done this, you will need to login again, or

re-source the profile before continuing, so that at least $QTDIR

and $PATH are set. Without these the installation will halt with an error

message.

 

 

On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.

 

 

3. Install your license file as $HOME/.qt-license.

For the free edition, you do not need a license file.

 

 

4. Building.

 

This step compiles the Qt library, and builds the example programs,

the tutorial, and the tools (e.g. Qt Designer).

 

Type:

 

./configure

 

This will configure the Qt library for your machine. Note that

GIF support is turned off by default. Run ./configure -help

to get a list of configuration options. Read PLATFORMS for a

list of supported platforms.

 

To create the library and compile all the examples and the

tutorial, type:

 

make

 

If your platform or compiler is not supported, please contact us at

qt-bugs@trolltech.com so that we can assist you. If it is supported

but you have problems, see http://www.trolltech.com/platforms/

 

 

At this point you have binaries created in $QTDIR (eg. $QTDIR/lib/

contains libqt.so). If, however, you would like to have your Qt

installed in a non-local installation you can run configure with

options splitting Qt into different areas for example:

 

./configure -libdir /usr/local/lib -bindir /usr/local/bin -headerdir /usr/local/include/qt

 

Then after a successfull make you can:

 

make install

 

This will install Qt onto your machine using the paths you've set.

(See ./configure -help for more information). If you choose to

install Qt like this, remember that you must set your

LD_LIBRARY_PATH to match your -libdir and your QTDIR to your

-headerdir (as described in (2) above).

 

 

5. In very few cases you may need to run /sbin/ldconfig or something

similar at this point if you are using shared libraries.

 

If you have problems running the example programs, e.g. messages like

 

can't load library 'libqt.so.3'

 

you probably need to put a reference to the qt library in a

configuration file and run /sbin/ldconfig as root on your system.

And don't forget to set LD_LIBRARY_PATH as explained in (2) above.

 

 

6. The online HTML documentation is installed in /usr/local/qt/doc/html/

The main page is /usr/local/qt/doc/html/index.html

The man pages are installed in /usr/local/qt/doc/man/

 

 

 

That's all. Qt is now installed."

Found an rpm on rpmfind :) Will try it later.

 

Have a lot to learn about Linux.

Unfortunately, the when I run the RPm it tells me that qt in already installed...hhhmmm

Okay, I just upgraded Qt instead of uninstalling.
