[Plplot-general] Working on PLplot 5.14 and gtk-fortran interfacing...

[Vincent M. <vin...@po...>]

Hi Alan,

this is a report of my progress toward interfacing gtk-fortran and 
PLplot 5.14:

1) I finally installed in a virtual machine a Debian Sid (unstable) 
because if offers the PLplot 5.14 packages.

2) I have installed the following packages for gtk-fortran and PLplot:

# apt install git gitk cmake gfortran libgtk2.0-dev libgtk-3-dev 
libplplot-dev plplot-doc

I have successfully built the PLplot examples:

# cd /usr/share/doc/plplot-doc/examples/
# make
# ./x00c

I have tried some examples and successfully created output files using:

< 3> ps         PostScript File (monochrome)
<11> svg        Scalable Vector Graphics (SVG 1.1)

But for an unknown reason failed to plot anything directly on screen 
(xwin, tk, qt drivers...) although plplot-driver-qt, 
plplot-driver-wxwidgets and plplot-driver-xwin are installed. With that 
kind of message (x33c):

Enter device number or keyword: 1

*** PLPLOT ERROR, IMMEDIATE EXIT ***
Can't open display
Program aborted

3) On the gtk-fortran side,**when trying to build the project, CMake 
found PLplot but stopped me with errors like:

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/plplot/export_plplot.cmake:175 (message):
   The imported target "PLPLOT::tclmatrix" references the file

  "/usr/lib/x86_64-linux-gnu/libtclmatrix.so.10.3.0"

   but this file does not exist.  Possible reasons include:
...

Using apt-file, I saw that it was in the plplot-tcl package so I 
installed plplot-tcl-dev. Then I was similarly obliged to install 
octave-plplot.

But I am now stopped by this error:

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/plplot/export_plplot.cmake:175 (message):
   The imported target "PLPLOT::plplot_pyqt5" references the file

      "/usr/lib/python3/dist-packages/plplot_pyqt5.so"

   but this file does not exist.  Possible reasons include:

...

I have installed the python3-plplot-qt package:

root@osboxes:~# apt-file search plplot_pyqt5
python3-plplot-qt: /usr/lib/python3/dist-packages/plplot_pyqt5.cpython-37m-x86_64-linux-gnu.so
root@osboxes:~# apt install python3-plplot-qt

But CMake still gives me the same error because in that package the file 
is named plplot_pyqt5.cpython-37m-x86_64-linux-gnu.so instead of 
plplot_pyqt5.so.

Note that in my previous email, I reported similar things under Kubuntu 
18.10 with PLplot 5.13, except that I was stopped by another file: 
PLplot needed the file _Pltk_init.so (python-plplot package) which is 
named _Pltk_init.x86_64-linux-gnu.so in Kubuntu 18.10.


Can you tell me what you think about that problem ? (is it a PLplot 
problem, a CMake problem, a Debian problem, a gtk-fortran problem ?)

Cheers

Vincent
