Hello, I am reposting the mail, as it was blocked by the lists platform: -- Message transféré -- From: Victoria French victoria.fre...@metrosharp.co To: devel@lists.monobjc.net Date: Tue, 19 Jul 2011 13:11:05 -0500 Subject: Re: [devel@lists.monobjc.net] iPhone / iPad ? I can't speak for Novel here, but I can tell you that first there would need to be a very special version of mono made itself. I would have to not only be compiled to run on Apple A chips but the concept itself needs changing. Mono would no longer be able to run without being pre-jitted at compile time to native code (Apples rule on interprereted languages). Then the entire framework would need to be a static library (.o) instead of a dynamic one (ex .dylib, .dll) again Apples rule on linking to dynamic libraries. After all the necessary changes to Mono was completed then Monobj could be ported but again lies the dynamic linking rule. I can see why Novell is charging for MonoTouch, the amount of work to make this a reality is insane. Think if your app had to load the entire mono library in memory! You would immediately end up with the phone rebooting. You only get 128M of ram, no paging file and your entire application gets loaded into that memory space before you can even execute a line of code. $400 is cheaper than trying to get someone else to do this or even doing it yourself IMO.

Re-posting... -- Message transféré -- From: Matt Emson memson.li...@googlemail.com To: devel@lists.monobjc.net Date: Thu, 21 Jul 2011 14:35:03 +0100 Subject: Re: [devel@lists.monobjc.net] iPhone / iPad ? ** Okay - here is the official line (having had this discussion with Miguel after the MonoTouch beta went gold and they announced the steep pricing that pretty much made it unworkable for me and many hobbyist coders) : No, not possible. This is for a few reasons: 1) Mono is licensed under many different OSS Licenses - but key parts of the runtime as LGPL. Basically, if you static link, you are required to get a commercial license. 2) Apple do not permit GPL code in the App Store. 3) To create iPhone apps, the mono runtime needs to be statically inked and the code needs to be AOT compiled to ARM native code. Therefore, you NEED a static bound runtime. When cornered, Miguel pretty much said - there is no way to legally do this without paying for a commercial license, and $399 was the cheapest that Novell had aver sold a single seat license to a developer. I looked at the alternatives, and they are slim. Portable.Net has even bigger restrictions and is very out of date now. The Microsoft implementations are either close, or fairly incomplete (micro.net) or not licensed for commercial use (the Community Source version of the compiler that they release a number of years ago and then updated for .Net 2.0). There's another option - someone created their own simple .Net runtime for embedded use, all free and perfectly able to work - but it has no UI kit and I only started to slowly look at embedding it before my dev account lapsed and I decided not to renew. Google DNA or DotNet Anywhere for more info. I've ported it at least to an intel Mac and run on Windows, so it might work. The issues I had was lack of linking ability for iPhone. You'd need to incorporate the App kit in to the runtime to get it to function peoperly. I got as far as routing managed calls to native calls embedded in the actual exe runtime (it was a bit hacky, but it was working) so it might be possible... The other alternative would be to use the Mono compilers, but rewrite the runtime... DNA might work for that, or maybe at a push the Micro.Net... never looked at it from that angle, so can;t comment further, Matt On 21/07/2011 13:55, Laurent Etiemble wrote: Hello, There are several points before running Monobjc on an iOS device: - Getting Mono to build and run on iOS (feasible with the right switches) - Getting the native part of Monobjc to build and run on iOS (one caveat is libFFI, but is seems that there is now a support for iOS devices) - Be able to link and shrink all the assemblies so the IL code is the smallest one (this is the hardest part) - Wrapping everything into an executable (this looks like the embedding done on the Mac), and link statically with Mono.

Re: [devel@lists.monobjc.net] Migrating to 3.0: - System.EntryPointNotFoundException: monobjc_install_bridge?
Hello, The 3.0 release use a mono wrapper that replace the old script-based launcher and the native library. If I recall well, you are using custom build process, so you have to update it to use the new wrapper: - The mono wrapper binary can be found in the dist/10.x folder of the distribution. It is named runtime. - Copy it to the MacOS folder of the application bundle and rename it to match the application bundle name. As for the Ids returned instead of proper object, can you send me a list so I can fix the wrapper generator ? Regards, Laurent Etiemble. 2011/3/18 marc hoffman m...@elitedev.com Hi, i'm trying to migrate a Monobjc 2 to v3, because im seeing weird crashes under Mono 2.10, and not sure if those are caused by using an old Monobjc. in any case, i made all the changes to the code to reflect the new APIs (not a step forward imho btw, most of the changes i had to make were extra casts for places were Id is being returned instead of the proper object. i'm disappointed), but when i run, i get this error: Unhandled Exception: System.TypeInitializationException: An exception was thrown by the type initializer for Monobjc.ObjectiveCRuntime --- System.EntryPointNotFoundException: monobjc_install_bridge at (wrapper managed-to-native) Monobjc.NativeMethods:InstallBridge () at Monobjc.ObjectiveCRuntime..cctor () [0x0] in filename unknown:0 --- End of inner exception stack trace --- at CocoaApplication1.Program.Main () [0x0] in filename unknown:0 (the proper dylib is deployed next to the startup binary) what could i be missing?

Re: [devel@lists.monobjc.net] NSMatrix GetRowColumnAtPoint
Hello,
It seems to be a problem in the way the binding is done for
GetRowColumnForPoint. It should use by-ref integers instead of integers. I
will take a look at it. Can you log a bug in the tracker (
http://tracker.monobjc.net) ?
Regards, Laurent Etiemble.
2010/7/30 Fluffy D. Bunny fluffydevilbu...@gmail.com
Hi All,
I have subclassed NSMatrix which is working fine and I have added the
following code.
[ObjectiveCMessage(rightMouseDown:)]
public override void RightMouseDown (NSEvent theEvent)
{
NSPoint location = this.ConvertPointFromView(theEvent.LocationInWindow,
null);
int row = 0;
int column = 0;
bool result = this.GetRowColumnForPoint(row, column, location);
this.SendMessageSuper(ThisClass, rightMouseDown:, theEvent);
}
When I call GetRowColumnForPoint I crash with the following error:
Stacktrace:

Re: [de...@lists.monobjc.net] Newbie trying tutorial console app
Hello, For the point 1, you have spotted a typo in the listing !!! The generic parameter was swalloded as a HTML tag, so it has disappeared. I have fixed the listing to be correct. For the point 2, you need to copy the native libraries libmonobjc.1.dylib and libmonobjc.2.dylib into the lib folder. The screenshots are a bit out-of-date (so they don't appear), but the text is accurate.
