Re: [fpc-other] ESCAPE: Environment for the Simulation of Computer Architectures for the Purpose of Education
Looks interesting. Does this still compile under Delphi ? I guess I could try it out myself, but a bit busy now...

We've used it since then every year in the lab sessions for our computer architecuture classes. In 2010, I ported the program to FPC and Lazarus and we use it compiled for Linux/Qt in a VM nowadays. I did not have any Lazarus experience when I started that port (and I'm still far from an expert), but the process still went fairly smooth. I recently asked for and got permission to publish the source code under the GPLv3, so here it is: https://github.com/jmaebe/ESCAPE Jonas ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

Re: [fpc-other] ESCAPE: Environment for the Simulation of Computer Architectures for the Purpose of Education
Ok, I tried and compiled the Delphi version. Only issue Delphi XE7 ran into was DirectorySeparator. TPath.DirectorySeparator did not seem to work. So I replaced it lazy with '\' for now to see if it would compile. It does compile and run. However there is some problem with the examples as far as I can tell. When loading micro.mpr there is a file format error stating that microcode may be incorrect. I may have to try the pre-build executables or try lazarus later on. Perhaps the Delphi version can be fixed/made compatible with the examples. When I click on about box in Delphi version it says: Escape 1.1.6 So it does seem to be a recent version and the same version as example material was written for: http://users.elis.ugent.be/escape/download.html#exercises Not sure what to make if this little error for now :) The GUI does look somewhat interesting. I find the project itself as an introduction to micro architecture a bit weird though. It's very much wired and such. I would have preferred a general/abstract introduction first and then only later a wired like approach as this. But this is very cool though. Don't know yet exactly how it works or how "hardcore" it is =D But it may be of some use some day to understand micro architecture better ! ;) =D I guess this was some kind of school/college/university material to teach people how to design real chips. Because for just understanding the software side of it, it would be a bit too much overkill ? to much down to the wire ? For actually hardware/chip design it seems to be just fine ! ;) Though those are also programmed in software but ofcourse timing and wires come into play with that as well I would imagine ! ;) Bye, Skybuck. P.S.: I am to busy leveling up in world of warships nowadays ! LOL :) But when the day comes I am done with that... who knows... I might dive into this project a little bit more lol :) ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

[fpc-other] Re: NoTarget could also be a target
Bit sloppy of me not to include a solution...
I guess a simple solution would be:
const
ConstNoTargetUnUsed1 = 0;
{$if defined(i386)}
bla = 1;
{$ifend}
{if defined(arm))
bla = 2;
{$ifend}
This constant is just there to smooth over the compile process...
ConstNoTargetUnUsed1
In other locations
ConstNoTargetUnUsed2 could be introduced as well...
Perhaps a {if defined(NoTarget)) might be usefull somewhere...
but for the const it probably needs a default constant which is never
used...
A cleaner solution is probably to just wrap the const in a conditional like
so:
{$if Defined(i386) or Defined(Arm) or Defined(Etc))
const
{$ifend}
{$if Defined(i386))
bla = 1
{ifend}
{if Defined(arm))
bla = 2
{ifend}
And so forth...
Bye,
Skybuck.

Subject: NoTarget could also be a target
Hello
I noticed a certain little problem with the free pascal compiler code.
Some sections assuming that at least one define is present.
for example:
const
{$if defined(i386)}
bla = 1;
{$ifend}
{if defined(arm))
bla = 2;
{$ifend}
^ This creates a little problem when no target or no defines are present.
Perhaps no target could be the default (or unknown target) (in case an
operating system is ever called no ;) :))
By adding a no target as a potential target this would allow to test
certain parts of the compiler without actually having to specify a
target...
Bye,
Skybuck.

[fpc-other] Running Mac OS X in emulator on Windows ?
Hello, I would like to experiment with free pascal and Mac OS X, maybe even Lazarus. However I would like to run Mac OS X inside some kind of emulator. I tried Virtual PC and PearPC without much luck. I tried some torrents from the pirate bay.. not much luck. Is anybody actually running Max OS X inside an emulator on windows successfully ? The farthest I got was with PearPC and PearPC Control Panel.. however that last application screws with filedisk driver which is bad. (I also used Power ISO 4.3 to convert DMG to ISO...) The error I got from pearpc was something about memory fail for the dmg to iso thingy... other torrent/iso said can't find file or whatever. (it was osx86 which probably can't run in pearpc... also tried it in virtual pc which didn't work as well) Kinda pissing me off a bit why can't I play with Mac OS X BOEHOE ?! ;) :) Stupid Steve Jobs ! :) I suspect some cross platform developers might be moving towards Mac OS X since... windows can run on it... So Mac OS X seems nice for cross platform development with emulators... while Windows sux ? Maybe time for Bill Gates to frag Steve Jobs up his peep and make sure Windows doesn't run on Mac OS X as well ? ;) But then again... Maybe Apple users will start liking Windows and simply switch to windows ! LOL... probably not though ? ;) Bye, Skybuck. ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-other
