Re: Building gnuplot 6.0.0 on Linux Mint

Since I went to the trouble of installing Linux Mint, here is a (final?) report
on building gnuplot 6.0.0 for Mint 21.3 Virginia

The Qt6  *.dev packages for Mint are defective; they are missing files
needed to build applications against Qt6.   Please take that up with Mint.
So far as I can see (but I did not actually install + build) the necessary files
are present in the upstream Debian packages they are derived from.
What went wrong between those two endpoints? I don't know.

Qt5, however, works fine.  I was able to configure + build gnuplot with

$ apt install libqt5*dev qttools5-dev-tools
$ ./configure --with-qt=qt5
$ make

For completeness, to add the cairo terminals, wxt, and lua/tikz

$ apt install libcairo-dev libpango1.0-dev
$ apt install libwxgtk3.0-gtk3-dev libgl-dev
$ apt install lua5.2 liblua5.2-dev

The resulting executable passed the "make check" test of running
the demo collection.

So I think the bottom line is that gnuplot's configure script is OK,
but Mint 21.3 does not provide a working devel package set for Qt6.
I did not go the the trouble of installing a full TeX distribution, so
I could not test the tikz terminal output or regeneration of the
full documentation set.
