Info needed on export command


I have tried man for export and came up with nothing. Googling for info on this command finds things that are over my head or in a different context from what I am using it for. Perhaps someone could provide me some insight for using it in my situation.

I use a debian-style installed Kanotix and am looking to install some KDE apps that do not have deb packages available. For instance, kexi. I have run into the problem when installing other apps that debian puts files in places the config doesn't know to look. In these cases I have edited the config files per the readmes or install instructions. In the case of kexi, they are advising to use the export command for several debian specific path problems and I am not at all familiar with export. Such as:

Some distros (like Debian) split KDE into several directories.

In Debian configure doesn't recognize the kde HTML directory. For correct
installation of the handbook in Debian do:

export kde_htmldir=/usr/share/doc/kde/HTML

This was tested with debian woody and KDE 3.1.2 but it's probably needed
for other distros too.


Now comes the pure noobish question(s): just where/when do I enter this command in the install procedure? Before beginning with ./ configure? From what I have googled up on export it changes a default path in the bash shell. Is this change "permanent"? for want of a better word. Anyway, could someone give me an easier to understand explanation of what export does at least in this circumstance? I also run up against Debian putting KDE in /usr and the instructions are recommending to use export for this as well, KDEDIR=/usr

Well, export sets the environment variable. To see all the environment variables for that session, open up a terminal and type 'env' without the single quotes. I believe that the variable is set until the next time your bashrc, bash_profile or /etc/profile are sourced, which happens when you open up a new terminal or switch consoles. So if you are ready to compile something that needs a specific environment variable, you can set it prior to doing the configure step:
export whatever=wherever
./configure

Should be appropriate. I don't know if that helps, but that's about as good as I understand it without going into programming terms that I don't understand

Cool

Thank you that is exactly what I wanted to know about it. Knowing this, I assume I can just start off with these export commands before doing the configure, make and install. My concern was that the "environment" I was setting up would be permanent (although even if it was, it is only telling the "truth" where those files are located, right? )
