Re: [Gnuplot-info] Building gnuplot 6.0.0 on Linux Mint

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

Oh!

I am wondering if something has changed in the gnuplot build process? Or 
maybe the openSUSE and Ubuntu distros have (both) changed something for 
Qt6 that means the gnuplot build now fails?

I have to confess that my knowledge of autotools is rather hazy. What is 
configure looking for (and cannot now find) when it looks for the 
presence of the Qt6 libs?

P.
