Re: [Gnuplot-info] Font problem in 2-lines titles with cairo terminals

[Peter R. <p.r...@sh...>]

The wxgtk-3.0 and readline8 versions will probably work. They are just 
later versions and unlikely to break things.

You will need to install the *-dev variants of the libraries to build 
anything. ('dev' for developer.) They provide the necessary header files 
without which you will get "header files do not exist" errors.
