More build problems with rc2

[Philipp K. J. <ja...@ie...>]

I now installed pango, cairo, and wxt dev
libraries, and the compilation continues
further, but breaks on a Qt dependency:

qtterminal/qt_term.cpp:51:10: fatal error: QtCore: No such file or
directory 51 | #include <QtCore>

1) 
Is there a way to build gnuplot w/o Qt?

2) 
Any hints what minimal set of Qt libs is 
required to build gnuplot? I looked through 
the various libqt5 dev packages, but most 
seem to be about "add-on" functionality (like
XML or networking). I could not find any "core"
libqt5 dev packages. Do I have the name wrong?

Best,

		Ph.

./configure --without-qt

For my machine the required modules are

Qt5Core Qt5Gui Qt5Network Qt5Svg Qt5PrintSupport

which are provided by packages

qtbase5-common-devel
lib64qt5base5-devel
lib64qt5core-devel
lib64qt5gui-devel
lib64qt5network-devel
lib64qt5svg-devel
lib64qt5printsupport-devel

It also requires (for the internationalization and locale support)
qttools5

Installing these will probably pull in other packages as well.

Thank you! 

Builds now, without further problems.
Excited to check it out!

Regarding Qt: 

Is that flag actually strictly necessary? 
I had thought the build process would discover 
that there are no Qt libs installed and skip 
the dependency...

Thanks for providing the list of required
libraries - that should help avoid much 
trial-n-error. Unfortunately, I can't seem 
to find them, or equivalent, for my own
system (Debian/Ubuntu/Mint based). I did 
not dig too deep, but I can't find any 
"lib64qt5..." libs, only "libqt5*", but
those don't have -dev or -devel variants.

Strange. Maybe I need to add a non-standard
repository. (No need to research that, but I
find it odd.)

But mostly: Thanks again.
Excited to check out gp6! ;-)

If you want to know how to build on Debian, consult the debianization.
The control file:

  https://salsa.debian.org/science-team/gnuplot/-/blob/master/debian/control

So the qt packages required to build the gnuplot package, as configured
by Debian are:

               qtbase5-dev
               qtbase5-dev-tools
               qttools5-dev-tools
               libqt5svg5-dev

Thank you, that's very helpful. Those pkgs do
exist for my distro, no problem. 

Thanks again.

Let me actually say one more thing. You can ask apt to install
everything needed to build a package:

  apt-get build-dep gnuplot

When that is done, you'll be guaranteed to be able to build the gnuplot
Debian package. Granted, you're trying to build a later version, from
source, with a possibly-different configuration, but it should still be
largely the same.

Hah - that's pretty clever. I would never
have thought of that, but it makes total
sense.

Thanks!
