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

[hchiPer <hc...@gm...>]

Hi,

I use gnuplot 5.4 on a Debian 11 based distro.

I have plots with 2-lines title with a font-face and font-size different 
from the default.
When the first line in the title contains an (escaped) *ampersand*, the 
font-face and font-size are reset to the default ones when using the 
following terminals: pngcairo, pdfcairo, epscairo.
No problem with other terminals (png, wxt, qt, ...)

This problem appeared when I upgraded gnuplot from 5.2 to 5.4.

Is this a bug?

Thanks for your help.

Code to reproduce:

tit1 = "A \\& B"
tit2 = "X + Y"
set title tit1."\n".tit2 font "Serif,24"
set terminal wxt
plot x
set terminal pngcairo        # or pdfcairo or epscairo
set output "ampersand.png"   # or  .pdf    or  .eps
replot
set output

By visual inspection with qpdf and geeqie, the two-line titles of
three plots in question appear much larger than used to (and in both
lines are in serif font, likely BitstreamVera-Serif Roman).  Thus, I
speculate a more recent version of (repackaged) Gnuplot does not
yield a reset in font size and cast or/and a question of the program
used to display the resulting .png, .eps, .pdf.  (As anticipated, the
title of the curve is the sans serif font used for the axes.)

[hchiPer <hc...@gm...>]

Thanks for your replies.

It seems 5.4.3 brings the solution, but I'm unable to find a .deb 
package. And unluckily I'm not able to compile myself.

As far as I know, 5.4.2 is the latest version available in Debian 
repositories. I installed it instead of 5.4.1 but the problem is still 
there.

Perhaps I missed it, but what is the Linux «based on Debian 11» you
use?  Is it one of the ubuntu family, like Xubuntu?  Is it Linux Mint'
/Mint/, or the LDME 4 closer to Debian than Mint's Mint?  Perhaps
something specific to your distribution contributes to the problems
you report which might be beyond reach of Gnuplot.

Curiosity aside, I just fetched Gnuplot (Version 5.4 patchlevel 3,
last modified 2021-12-24) from sourceforge, decompressed the tar.gz
(4.5 Mo).  The INSTALL file (no file extension) describes well what
has to be done to perform the installation, which starts by entering
the decompressed archive from the terminal.  Then run from the
terminal `./configure`, followed by `make`, and `make check`.  For
the then following installation /per se/, you possibly need elevated
administrator privileges, i.e., `sudo make install`.  True, you have
to request `synaptic` once to get GNU Make (e.g., GNU Make 4.3 by
2020) to run the make command.  In my case, it overwrites synaptic's
earlier installation of Gnuplot 5.4 patchlevel 2 from Debian's
repositories.

Caveat: The installation based on the sourceforge archive does not
offer you access to wxterm, pngcairo, epscairo, or pdfcairo terminal.
Yet have the postscript terminal instead to generate a .eps with the
two-line plot title with escaped ampersand and both lines in serif
fonts greater than usually seen (by appearance /likely/ a different
serif font than the by Bistream Vera). 

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

[hchiPer <hc...@gm...>]

The distro I have installed is  Q4OS 4.7 (www.q4os.org). I began using 
it because it was said to require few resources and to run smoothly on 
rather old machines (mine is more than 10 years old).

I installed gnuplot 5.4.2 on another computer under Win10, and the font 
problem doesn't happen.

I suspect the cause of the problem is in the cairo or pango library, but 
I am not sure.

I was indeed able to compile 5.4.3, but without the terminals I use to 
use (wxt, pngcairo, pdfcairo), it is not very useful.

Thanks anyway for all your help :)

My experience of linix is for Ubuntu and its faimily (lubuntu and Xbuntu).
On Unbuntu

sudo apt build-dep gnuplot

The command installs build dependencies of gnuplot which is for binary distribution.
The commnad.is perhaps also effective on Debian.

Affirmative, this route exists for both Xubuntu and for Debian.
Though, depending on the setup of programs and libraries already
installed /prior/ to gnuplot this approach may request more
space to start/eventually offers additional functionality.

The estimates by `synaptic` on a live USB session with Xubuntu
(focal/20.04.2 LTS) are

+ `sudo apt-get install gnuplot-qt` (17 MB download, 70 MB installed)
+ `sudo apt-get install gnuplot-x11` (7 MB download, 25 MB installed)
+ `sudo apt build-dep gnuplot` (250 MB download, ~1 GB installed)

For Debian 12/bookworm (branch testing), the numbers are of similar
magnitude.  The third approach requires more space because it equally
installs for example parts of the TeX universe.  While some users of
gnuplot don't need/use this, other users already have it on board (for
pandoc, ipe; Emacs org-mode, etc.).

Thus Peter's more modular approach may be the one balanced between
your needs, and resolving gnuplot's dependencies.  To get familiar
with the process by a test run in a virtual machine is going to save
you time and nerves, too.  Bonne chance !

On Debian (and derivatives) you need to install libwxgtk2.8-dev (for the 
wxt terminal), libpango1.0-dev (for the cairo terminals) and 
libreadline5-dev (readline support (editing command lines). Follow the 
configure/make steps below and you should have wxt and the two cairo 
terminals. Carefully inspect the final lines of the build output since 
this tells you what has and has not been included; if anything you need 
is missing you will need to hunt down the necessary dependency.

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

[hchiPer <hc...@gm...>]

Great thanks for your response.

I tried this command and I got
"You must put some 'deb-src' URIs in your sources.list"

In /etc/apt/ the file sources.list exists and is empty.

In /etc/apt/sources.list.d/ there are some .list files
- 10_q4os.list
- 12_qtde.list
- 20_debian.list
- 30_debian_backports.list
- and 2 more (eid, megasync)
but in each of them all the lines beginning with deb-src are commented out.

For the moment, I don't feel confident enough in myself to try to 
uncomment some of these lines, randomly chosen, because I fear such 
"experimentation" might corrupt my system (I've not been a long time 
linux user and I know too few things).

My idea is to "experiment" first on a virtual machine, but I'll try 
later because I don't have much time right now.

Ah! I forgot it because I used linux in two years ago.

In  case of the vi editor
$ sudo vi /etc/apt/sources.list

In the vi replace "#" by ""
:%s/# deb-src/deb-src/
:wq

You can use the other editor ilike gedit, emacs etcs. instead.

After the edit,  exectute 
$ sudo apt update

and re-execute 
$ sudo apt build-dep gnuplot


This install alomost all dependenies including the TeXLive for building gnuplot manual and qt libraries for the qt terminal)
As Norwid pointed out, massy amount of files are installed.
If you dislike massy anount of files, you follow the Peter's suggestion.

Thanks for your reply.

libwxgtk2.8-dev:
only libwxgtk3.0-gtk3-devavailable and libwxgtk3.0-gtk3-0v5already installed

libpango1.0-dev:
libpango1.0-devavailable and libpango-1.0-0already installed

libreadline5-dev:
libreadline-dev(8.1-1) available and libreadline8already installed

I'll try this and Tatsuro's advices on a virtual machine first (as I 
wrote, I'm not an long time linux user and I fear to make something 
wrong that might corrupt my system).

Once again, thanks a lot for your help. Step by step I'm going deeper in 
linux knowledge.

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.

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

[hchiPer <hc...@gm...>]

Thanks a lot Peter.

In a virtual machine with the same distro (but 32 bits instead of 64) I 
have installed successfully (sudo apt install ...):
- libwxtgtk3.0-gtk3-dev
- libpango1.0-dev
- libreadline-dev
- libgd-dev

I compiled gnuplot (./configure ans make). And the cairo terminals were 
available. I never thought I could make it! The "ampersand problem" is 
solved with gnuplot 5.4.3 :)

One thing is that wxt (and qt) terminals are not available. I also often 
use wxt (and sometimes qt). In ./configure summary I read this:

- wxt terminal: no (requires c++, wxWidgets>2.6, cairo>0.9, pango>1.22)
- Qt terminal: no (use --with-qt or --with_qt=qt4)

cairo and pango are not the problem since they were required for the 
cairo terminals, which work fine.

For wxt, it seems I need to install c++ but I don't know exactly which 
package (apt list give a lot of possibilities) and libwxgtk3.0-gtk3-dev 
might be a wronk package...?

For qt, I tried ./configure --with-qt and ./configure --with-qt=qt4, but 
the same warning is still there.

Anyway I am very happy (and proud) to have been able to compile gnuplot 
successfully, thanks to your help.

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

[Tatsuro M. <tma...@ya...>]

For wxt terminal, something may be wrong for your intall of libwxgtk for build gnuplot.

In build directory, configure log file "config.log" exist,
open config.log, and search keyword "wx-config" and what is reported.
Please report here.

For qt terminal, qt libraries should be installed.
Note that hey must be massive libraries.

I recomend qt5 because qt4 is obsolate.
The below is the cygwin's build depends for qt5 library
libQt5Core-devel, libQt5Gui-devel, libQt5Svg-devel,
perhaps similar libs are required for the Debian.

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

[hchiPer <hc...@gm...>]

I looked at the log file. The problem was that no c++ compiler was 
found. I installed g++. Then I was able to build gnuplot 5.4.3 
successfully with a working wxt terminal.

I am very grateful to you, Peter and Norwid for having helped me. I also 
have learned several very useful things about compiling sources and 
tackling problems.

Happy end, thanks.
