Thank you for the quotes. This is exactly what I feared.


When reading such things about Delphi's problems I wonder what this
all means for FPC, Especially the following:
* will it ever be possible to build any kind of .exe for RT that will work?
* will it at least be possible to compile a .dll that can be loaded by
a native RT app?


If you want to make WinRT apps you'll need to add a new target to FPC 
that adheres to the WinRT rules and binds to the RTL DLL mentioned in 
those quotes...



* what exactly does "Win32" and "Win64" mean in the above quote in the
context of WinRT/ARM, he is talking about ARM code, isn't he? Would
the SafeSEH problem affect FPC programs or libraries too?


WinRT is what drives Metro apps. They are used on all three Windows 
platforms (x86, x86_64 and ARM) though on ARM they are the only possible 
way (without hacking Windows) for custom applications.



* will FPC be usable for anything at all on WinRT?


In it's current state: No.


* If the answer to the above is no then would it help to implement a
.NET bytecode target in FPC, would this improve the chances of making
it usable?


A .NET backend would at least solve the issue to have code written in 
Free Pascal running with WinRT, but you'd have the same problem as with 
the JVM backend: little to no code reuse (and someone would need to step 
up to develop a code generator which is not easy cake either).


It seems that from the perspective of a compiler developer WinRT is more 
tightly locked down than iOS... :(

Quote Allen Bauer:
"[...] Right now, the issues surrounding the WinRT space center around
the fact that many OS-supplied APIs which are required by anyone
implementing their own language RTL are actually off-limits unless
you're the VC++ RTL DLL. You know, little things like RtlUnwind for
exception processing and VirtualAlloc (et. al.) for memory
management... Any calls to those APIs from your application will
automatically disqualify your application from being an "official"
WinRT application capable of delivering through the MS app store.

Right now the VC++ RTL DLL is given special dispensation since that is
the library that makes the calls to those forbidden APIs and not
directly from the user's app.

[...]

Like the APIs I mentioned above, there are lots of changes with WinRT
that make targeting it a little more tricky. For instance, you cannot
merely open any file, access the registry, and even use the loopback
(127.0.0.1) adaptor. LoadLibrary cannot be used to load any arbitrary
DLL; you must call LoadPackageLibrary and only on a DLL that is present
in the digitally signed appx package. WinRT is a seriously locked down
sandbox or "walled-garden" with some extremely high walls.

[...]"


or this one: https://forums.embarcadero.com/message.jspa?messageID=484771#484771

"[...] Something else I didn't mention was for 32bit applications under WinRT,
you must build all binaries using what MS calls SafeSEH. There is
precious little information about exactly what that entails. We know it
is special meta-data included with an executable that describes all
exception handlers throughout that image. However the format of said
meta-data isn't documented. I suspect it is similar to the .pdata
section of a Win64 image because SafeSEH only pertains to Win32.


The only thing we can find is a reference to the /SafeSEH switch for
VC++ which you set and it "does the right thing." Gosh, thanks... so
all I have to do is recognize that switch with Delphi and it will
magically "do the right thing" ;-). Yeah that's the ticket.

Why not? I thought that WinRT is just the same as normal Win32/64
apps, but the availables APIs are different. Or am I wrong?



I have not yet looked into it deeply, but applications that use WinRT 
can be normal binary applications (this includes managed ones) and also 
HTML5/JavaScript based ones. The latter is not that intresting for this 
topic, so I'll concentrate on the former. Those apps then use the APIs 
provided by WinRT and only those. The operating system can then check 
whether the application behaves "good" and only uses that APIs and then 
allows to run it on "locked down" versions of Windows like the ARM 
version of Windows 8. Only the non-WinRT applications provided by 
Microsoft (Explorer, System Control, Task Manager, etc.) are allowed to 
run on Windows ARM.


So to support running LCL applications on WinRT only (like is needed on 
a locked down Windows 8 ARM) we'd need to be able to support WinRT and 
then maybe (as best solution) provide a CustomDrawn target for WinRT 
without resorting to the normal WinAPI (though I'm not really sure 
whether any WinAPI usage is not allowed - if that is really the case 
we'd need a new compiler target for WinRT).


If we'd have a "unlocked" Windows 8 ARM though we should rather easily 
be able to provide a new arm-win32 target which allows to run normal 
LCL-win32 applications on that system...

LCL-WinCE is productive enough. Some rough edges here and there, but 
besides that it works. If you want to target Windows Mobile easily I 
would stay with LCL-WinCE instead of using yet another abstraction layer

the Qt devs might also be likely to decrease or even stop development on 
WinCE...



In general (not mentioned as insult ;) ) I think Lazarus should reduce
the "supported" Widgetsets etc. If something is not top notch quality it
should be dropped or marked as some kind of an official hobby projet or
something like that. Just because Lazarus is an Huge system along with
the FPC.  So us that are not inside the project and hacking it in and
out could see more clearly where to go with it. To choose right
widgetset...


The activity on WinCE is already rather low (though not as much as on 
GTK 1). So besides keeping it compiling and happy there isn't much time 
going in anyways.

Apparently there is something different, but I don't know the details. 
Microsoft is not allowing other compilers to support true WinRT 
development. See the recent messages in the Embarcadero non-technical 
newsgroup. Embarcadero has tried to get some deal going with Microsoft, 
but Microsoft stone-walled them at every step. :-(

WinCE is unfortunately a dying breed, but there are still millions of 
devices out there running WinCE (hand-held scanners, PDA's like my own etc).


You could also take a look at fpGUI Toolkit. Paul Breneman put together 
a small fpc+fpgui archive (2-4MB download) to get you started really 
fast. Unpack, and you are ready to compile - no other installation 
required. With fpGUI on WinCE you also get very small executable sizes 
as a bonus.


  http://www.turbocontrol.com/easyfpgui.htm

Going the Qt route as you mentioned, would require extra runtime 
libraries etc, where with fpGUI and LCL you don't. So deployment with 
the latter two is easier and smaller.

I should have been more specific: industrial hand-held devices (PDAs) used
in surveying, data collection, mobile scanners. See this article for
examples: http://ruggedpcreview.com/2_handhelds.html

At the bottom of that article:

"While the vast majority of consumer handhelds are either iPhones or
Android-based smartphones from Motorola, HTC, Samsung or LG and have large
(3.5 to 5.0 inch) displays projected capactive touch screens, industrial
handhelds continue to hold on to an earlier era. The majority of ruggedized
handhelds remain based on Windows CE or Windows Mobile and have resistive
digitizers."

Of course this is changing, but companies have invested heavily in this
kind of hardware and unlike consumer devices that come and go with every
new fad, these industrial devices need to be supported for many years to
come.

We have had very much problems with out WinCE-based project. And

It is not only the Lazarus and it's WinCE implementation. It is also 
about Windows Mobile OS and how they are fitted on Hardware and how 
Hardware is made (and designed).


my ex colleague writes apps to the Windows Mobile with C# and .NOT with 
using Visual Studio. And He have had huge problems with the Devices, 
even using Microsoft solutions to development.


So any ideas how I could use Lazarus to target Windows Mobile or similar 
tugged PDA platforms?? Is there any real alternatives. that would be 
more than less better choice???


As you state development is Slow and if the this line of M$-operating 
systems are going to die sooner or later, I am just looking for the some 
other platforms that would be supported in way or other. Or something 
like Qt, where is huge amount of people coding ir (not sure how Lazarus

Windows Mobile remains the only operating system on industrial devices, as
opposed to consumer. (Or please prove me wrong!)

Huge thanks to you, Felipe for maintaining LCL-WinCE. I have nearly 200
Trimble Juno handhelds in the field running on LCL-WinCE. (Not without
nearly killing myself during the development, I might add :-) )

I was wondering the other day... how about LCL-CustomDrawn-WinCE ?

Regards,

Paul.

Why do you think that? LCL-WinCE was always one of the top downloads
of Lazarus with 10.000+ downloads per release.

And in Lazarus 1.0 it is keeping up the same proportion. It has 10% of
the total Windows downloads:

http://sourceforge.net/projects/lazarus/files/Lazarus%20Windows%2032%20bits/Lazarus%201.0/

Development indeed is slow, but the interface is essentially finished,
so there is not much to do. Almost everything works.

And besides that the operating system is no longer utilized in
smartphones, so I lost my personal interrest on it and moved to
Android development instead (LCL-CustomDrawn-Android). I have to
invest in platforms which are actively used in my field...

But I still fix major bugs that appear for LCL-WinCE, despite all that.

[Lazarus] Alternatives to WinCE (Windows Mobile)

2012-08-30 Thread Tommi Prami

Hello,

Seems that there is not much support/users of WinCE-Lazarus so I was 
just pondering what are the options on here...


1. Could QT with Lazarus be viable option to get more robust development 
tool and environment on Windows Mobile?


2. Is there rugged Linux devices (with significant user base) so it 
could be targeted with Lazarus. Device must be widely supported so it 
would stay around long enough...


3. Ditch the PDA and go for rugged Windows PC (This would be easiest for 
me, but getting this decision trough is very difficult, I think... )


Any other ideas on this???
