Re: [Freedos-devel] FreePascal bug [off-list]
The bug description is very confusing. It is not clear whether user complains about missing Video unit (files VIDEO.PPU and VIDEO.O) or the fact that under DOS/GO32V2 platform are not available the GUI Delphi-like elements. If it is the firsr case it is probably a LFN related problem. The Video unit is in the RTL-CONSOLE subdirectory. Without LFN it is not visible. The solution is the renaming this subdirectory to 8.3 format and to edit the FPC.CFG and FP.CFG files in the BIN\GO32V2 directory. ___ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
Re: [Freedos-devel] FreePascal bug [off-list]
Hello, As for myself, I attempted to compile FD-KEYB with FPC 16-bit, which I find to be a good proof, as it has heavy parts in Assembler, other parts in Pascal, and many procedure-type variables. It helped me fix a couple of minor (almost cometic) failures in the code. But I did not succeed. The problems came when mangling with procedure/function-type variables especially with far/near procedures, etc. I posted in the list, but I assume that DOS programming is not that exciting these days. I tried to isolate the problem, but when requested to post the whole program, I did not get any useful replies in the mailing list, so I quitted. Maybe to retry some day :) (all the other corrections were pushed into the latest KEYB version).

I don't do a lot of graphical programming, so I'm unfamiliar with the
"Video" unit.
"9 Units that come with Free Pascal"
"9.1 Standard units"
* https://www.freepascal.org/docs-html/user/userse47.html#x157-1640009.1
It lists several, including "video":
"
video
Provides basic screen handling in a platform independent way, and
supports writing custom drivers.
"
I don't think this is meant to be "{$mode tp}" [turbo] compatible
(which only had "graph" and text mode "crt").
What are they trying to do, SVGA? VESA? Maybe something like Allegro
(lib) could help.

It's probably only used internally by some FPC utils, if even that
much. Maybe it has no maintainer or bitrotted, I don't know. But I've
never seen it used.

I was going to (finally) reply to say they really should ask the FreePascal people about this, but I realized I couldn't really make out what they were saying. This is the part of their email that relates to the FreePascal problem: I believe this is a Free Pascal issue because the short hello world test works, but if you decide to use any objects, the Video unit is completely missing. There is reference to consolidation of the video functions but no references to where the the functions in that unit went. Actually as good as Free Pascal are, they are getting pretty sloppy with keeping their work updates current in their wiki. There are a lot of circular references that are dead ends when it comes to useful information for experienced users. Not sure what this is talking about, but I'm not a Pascal programmer. And their email kept going off onto tangents, so it was hard to follow. Does this "bug report" make sense to anyone? Well, (s)he is rather thin on any details, but it sounds as if the OP expects that FreePascal is a drop-in replacement for Turbo-Pascal. Which it isn't. The 16bit x86 (DOS) version is a bit of a step child at FreePascal, and I am not sure how usable the latest version of this actually is. This is on my to-do list, unfortunately currently further to the end of that, to check and verify how much work it is to get old Turbo Pascal stuff working with the 16bit version. And the 32bit version (using the GO32 DOS Extender) has also been behind the general development of FP, with some of the OOP stuff probably not applicable at all anymore.
