Hello, Please note that the original poster isn't subscribed to the list apparently, you may better include him in Cc: when responding (doing that myself now).
As far as I can tell, the issue may be more likely related to the packaging of a particular Linux distribution (Raspbian in this case?) than FPC itself. Obviously, it should be possible to build either just the required packages with the FPC version distributed there, or the complete latest release of FPC there, but that obviously needs some additional effort. In any case, questions about not having PTC included with Raspbian might be better sent to the respective maintainer of Raspbian.

Gareth Moreton" <gar...@moreton-family.com> Date: Wed, March 27, 2019 09:56 To: "FPC developers' list" <fpc-devel@lists.freepascal.org> Hello there Yves Boudeville, That's great to hear that Pascal has served you well with scientific programming and the like. I confess unfortunately I'm not familiar with the units, but I will be happy to see if I can help optimise them in places, either by writing platform-specific assembly language (with a Pascal fallback if it's not Intel x86_64), kind of my speciality, or compiler improvements. Are you sure that PtcGraph isn't stil available? I just checked with the development version and it seems to be present. Gareth aka Kit. On Tue 26/03/19 08:07 , Yves Boudeville yves.boudevi...@free.fr sent: Bonjour. I am asking questions on the art of scientific computing from 1966. After Algol and Modula, the U.C.S.D. Pascal system has been the touchstone of the scientific computing. This has been devoted by Niklaus Wirth book and applied in Borland TP7 software. The only thing scientists need is a strongly typed language with pixel access on a single graphical windows. This is needed, for instance, by Monte-Carlo simulations. We need the full power of the computer with the pixel definition of the result because the eyes are the best investigators for scientific bugs. TP7 with graph was the best tool for that. For less mathematical approaches, like 3D models it was sufficient to use Borland Delphi-7. Now, in 2019, it was possible to use FPC compiler with Fp-IDE to make in laboratories good simulations of scientific equations, very clean in FPC Pascal, with the Graphical tools PtcGraph, PtcCrt, etc ... It is far more useful than old Seymour Cray Fortran or C// on Connection Machines CM1 / CM2 of Hillis : Theses need M.I.T. gourous in big National Laboratories. Some years ago, it was possible with the good job of Nikolay Nikolov on Ptc Pascal Units, to do clean-proof use of computer to visualize physics in HDMI 1920 x 1080 x 65536c under Windows. With lesser resolution, a work in Pascal was running without adding/changing a word under Windows_Intel / Ubuntu_Linux / or Raspbian_Raspberry Rpi3. Now, for scientific use, it is not possible because ptcgraph etc... are not included in latest versions, for instance of Raspbian. So, in order to use software in Physics, we are compelled use old versions of OS 2.6.4 Fpc systems instead of 3.0.0 on /usr/lib/fpc to use our programs. It is a big problem for us because we are interested by easy Pascal simulations of physics and we are newbie in systems. Will it be an hope to have again under Fpc : PtcGraph, PtcCrt, PtcMouse... to do good job in physics ? Friendly Yours. P.S. I beg your pardon for my desesperately rusty English language because Classrooms are very far from me in time ...
