Re: [fpc-pascal] Challenging port of Borland Pascal program to FPC
John Youngquist wrote: Interesting response. I routinely implement large systems on the 8051 chip in assembly language which I can write faster than Pascal. Assembly is a minimum of 500% faster than C on the 8051. I hate C anyway. The machine is a pick place machine designed to assemble SMT circuit boards. It was originally controlled by a Borland Basic program written in Japan without any useful comments. With 5 or 6 statements per line without even a single space it looked like Japanese to me. Initially I needed to fix a few bugs and add a few features so I studied the code for while - all 100K statements of it. I decided rewriting it from scratch would be faster that figuring it out. In exactly 2 weeks I had replicated and enhanced the original functionality with 3K lines of Pascal. I still had to study the code to figure out how drive their special hardware, but over the years all of it has been replaced with simpler stuff. Numerous enhancements have swelled the code to 8K lines using less than 2 64K blocks of memory. The before/after size ratio shows how poorly the basic was done. As implemented in BP it works very well. The multi-tasking part handles functions that are not time critical, operating air cylinders that don't know what a mSec is. The fast motion is handled independently by Animatics Smart motors. I have never explored the multimedia timers. I drive the LPT int to get my own periodic interrupt because the multi-task code already uses the timer. As you know there are 3 timers in the timer chip but only one will generate an interrupt. One problem I have yet to solve is the BP IDE when it hits a breakpoint kills my LPT interrupt. Nothing but an IDE restart will restore it. It sure cramps your debugging style. You may think http://www.freedos.org/ in a simple PC with Free Pascal http://www.freedos.org/cgi-bin/lsm.cgi?mode=dirdir=devel I think , you may directly use your Pascal program in DOS mode : Port I/O , Interrupts , etc. Thank you very much .

Ah... I can see it now:

This is where the = operator is required ( is derived from = ).
I continue the discussion in mantis, so that this can be solved (hopefully).
I've attached patch to mantis bug which makes compiler print error
about missing operator TPar = TPar. This could, at least, give
user some hint about what is wrong.
The proper solution for this problem is not simple. Somehow, you will
have to make operator = (const A, B: TPar) visible inside FGL unit
(because of the way generics are currently implemented), or make
compiler think that TPGList is implemented in the place where
specialization occurs (so compiler first searches specialization
space, and after that generic-declaration space).

[fpc-pascal] Re: creating a standalone executable (eg: applicationinstallation file)
- Original Message - From: Graeme Geldenhuys graemeg.lists-re5jqeeqqe8avxtiumw...@public.gmane.org Newsgroups: gmane.comp.compilers.free-pascal.general To: FPC-Pascal users discussions fpc-pascal-pd4fty7x32k2wbthl531ywd2fqjk+...@public.gmane.org Sent: Tuesday, January 12, 2010 11:37 PM Subject: creating a standalone executable (eg: applicationinstallation file) Hi, I have seen a few Linux application that have standalone executables that are installation programs. Once run, it installs the application in the appropriate directory location, can run as root or normal user and creates a desktop and Application menu icon. Similar to Windows's setup.exe idea. An example of such a Linux application is 'installpixel32' from the Pixel32 project, or Kylix 3 installation. * How does one create such a standalone application? * How do you include the application executable and other resources (text, image, sound files etc) inside such an installation executable? I'm trying to create (mainly for our company, but probably open-source in the end) such a standalone setup creation for our projects. This way it will be Linux distro independent. I also don't want to go the route of projects like AutoPackage that first requires a setup runtime to be installed. I want a installation file like what Pixel32 did. One installation executable without any installation runtime etc. and after the installation, I can simply click on 'uninstall' or run 'setup -u' and a graphical uninstaller is launched. I'm going to look at Loki Games's setup program to see if I can port it to fpGUI Toolkit, or at least get some ideas of how to create such a setup application. Basically I'm trying to create a InstallShield Lite but for Linux. :-) The nice thing of Loki Games is that it run run as a console installation or a GUI installation - again, no idea how they managed that, but it was possible (Kylix 3 installation did that).

I guess the author of that website didn't know about Makeself, which automates the exact same procedure he does manually. Either way, that seems to be the popular way of distributing applications in a distro independent manner. The installer I'm working on will probably start as a script, unpack itself and then figure out if it should run the Console setup or the GUI setup - depending if X11 is available and running. This will also allow me to pick the correct setup for the architecture (32bit or 64bit install, *BSD or Linux binary etc). So far my GUI setup is looking pretty neat and is completely configurable at runtime using a setup.xml file. Later I'll create a install builder which will generate that setup.xml file for the user/developer.
