want to set PATH for qt and having trouble

Hi i am a newbie !!
I have bash
I installed Qt libs and want to set environmental variable PATH, I tried some stuff from qt tutorials..
here is what i tried:

Code:

In .profile added the following lines:

 PATH=/path of bin:$PATH

 export PATH

and it does nothing
so i tried

Code:

PATH=$PATH:/usr/local/qt-everywhere-opensource-src-4.6.3/bin

then checked path

Code:

echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/qt-everywhere-opensource-src-4.6.3/bin

Now there are two issues
1) the make gives error that header not found( probably make don't have the path)

2) when i closed the terminal and opened it again the PATH I newly entered was not there !!

thanks in advance !!!

I would suggest that you try placing

Code:

PATH="/path of bin:$PATH"

export PATH

in "~/.bashrc".

Make sure that your .profile includes something to this affect:

Code:

# if running bash

if [ -n "$BASH_VERSION" ]; then

    # include .bashrc if it exists

    if [ -f "$HOME/.bashrc" ]; then

        . "$HOME/.bashrc"

    fi

fi

No doubt Ubuntu has setup their login process to be different from Debian, but this should work. If not, and it's a single-user computer, try placing the path in /etc/profile. Mine is set up like the following, but you should pay attention to how Ubuntu has structured things.

Code:

if [ "`id -u`" -eq 0 ]; then

  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

else

  PATH="/usr/local/bin:/usr/bin:/bin:/usr/games:$HOME/bin"

fi

export PATH

The reason your PATH change set through the cmd line didn't stay after restarting the terminal, is because changes made in that way will only stay in that session.

As for the make procedure, I haven't built Qt from source, so there you will have to check further into their documentation, but if there is a configure step, e.g.

Code:

$ configure --bin-directory=DIR --your-chosen switches

See whether you can utilise that method (Type

Code:

./configure --help

from the top-level source code directory.)

If I understand what you're trying to do with Qt, (You may be duplicating effort, but it's fun to experiment. :)) you might also find the attached text file useful. It's info I compiled from various sources some time back. While it doesn't apply exactly to your situation, I suspect that the issue I had to overcome may be the same as what you're trying to do now. One thing I would add is, don't overwrite existing PATHs. Before making changes, check the output of

Code:

echo $VARIABLE_YOU_ARE_LOOKING_FOR

If nothing pops up, you're good. As you already know, otherwise be sure to add the original path in

Code:

$ export "$PATH:$NEW_PATH"

Good Luck!!

You might also want to post the contents of PKG_CONFIG_PATH:

Code:

echo $PKG_CONFIG_PATH

This is where pkg-config (which make depends on) looks for the required headers and libraries.

firstly thanks all !!
Unfortunately what ofaring said is not working , nothing is happening and path is still the same !!
is there any alternative way to install Qt automatically (like using synaptic)
is there any .deb package of Qt available which will perform the tasks such as setting the environmental variables etc.
