My laptop has Slackware 12.2 and I installed gnuplot 4.2 patchlevel 5. But in this moment I need to install gnuplot 4.4. First I like to uninstall gnuplot 4.2, but I can't uninstall this programm.

I do
slackpkg remove gnuplot
and obtaining
Looking for gnuplot in package list. Please wait... DONE

The file remove can't be removed - package not installed.
after I do too
removepkg gnuplot
and obtaining
ls: cannot access /var/log/packages/gnuplot*: No such file or directory
No such package: /var/log/packages/gnuplot. Can't remove.

But Gnuplot 4.2 was installed at my laptop. I can do graphics and its version is
@science:~$ gnuplot --version
gnuplot 4.2 patchlevel 5
Please help me how to uninstall this version and to install gnuplot 4.4.

My guess is that it was installed by running it's own 'make install' process, so it does not appear in the package database and cannot be removed that way. The easy and complete way to do it would be to get the original version of the source and run 'make uninstall' (if it supports that.).

The easy dirty way to do it would be to look at the output of 'whereis gnuplot' and begin removing things from that list while THINKING CAREFULLY about what you are looking at.

Then install the new version using a slackbuild package.

EDIT:
See mRgOBLIN's post below - that is a better idea...

If you have the MANIFEST.bz2 handy you might check what is included in the stock package.

Thanks for your time and help.

I have the original version of the source (gnuplot-4.2.5.tar.gz). But at this folder is not file uninstall. I can't do make uninstall.

What can I do?

I install gnuplot by it's own 'make install' process

mRgOBLIN

I don't know nothing about MANIFEST.bz2.

Is a program?, What do it do?, Where do I get it?

Thanks for you help

Look for it in /var/log/packages, if you find it, let's say, something like this:

Than, if you're upgrading to a new one

Or, just issue a

rfernandez

At /var/log/packages/

is not the package gnuplot

but at /var/log/remove_packages

is a package gnuplot-4.2.5

but this a package doesn't uninstall because It is working

I can do graphics and export these graphics.

Why?

Since you have the original file do this - guaranteed to work (I think):

1.) tar -xvzf gnuplot-4.2.5.tar.gz
2.) cd into gnuplot-4.2.5/
3.) ./configure
4.) make
5.) make uninstall (must be run as root)

That will build the original package for your system, then uninstall it.

This should give you a clean uninstall before building the new one.

EDIT:
FWIW - I use gnuplot myself and was still using v4.2.3 with Slackware 12.1 on my laptop.
I decided to upgrade to v4.4.0 so I removed the old package and first built your version and tried the 'make uninstall' method for removal - it will work.
Then I built 4.4.0 with a slackbuild and am now running it under 12.1...
So I hope you get yours going - I got an upgrade for my trouble - thanks!
