gnuplot is one of those programs I can't live without. It's fair to say that 70% of the graphics I've published in my work were created with gnuplot, and the only reason that figure isn't higher is that I wrote a lot of papers before I found out about gnuplot.
The version supplied with Dapper is 4.0, but I found from an email that 4.2.rc4 was recently released. Going to the project home page I found that this release included support for animated GIFs, something that I was trying to create more or less by hand for an upcoming talk. Now expecting the new version to be available in Dapper is a bit much, so I went to SourceForge and downloaded the tarball. (Click on "Download gnuplot development," then on "4.2.rc4." It's not obvious.)
After a bit of tweaking, I found that I had to fire up synaptic and install the libreadline5-dev and libgd2-dev packages. These let me compile in readline support, so I can do things like tab-complete file names, and support for gif and png files, for the aforesaid animated gifs.
From there it's straightforward, using the checkinstall to create the .deb file:
$ untar gnuplot-4.2.rc4.tar.gz $ cd gnuplot-4.2.rc4 $ ./configure --with-readline=gnu --enable-history-file $ make $ sudo checkinstall -D make install-strip
This makes, and installs,
which works. Once I get the paper cleared and presented, I'll see about putting up one of the animated gifs as an example.
