Steema Central

Hi, I'm trying to deliver to our clients an application with TeeChart that runs perfectly on Simulator but fails on a real device.

When compiling, if I don't change linker options to "Don't link" (and then app become bigger) it gets a compilation error.
Then, with "Don't link" when I run it on device (on Simulator it's ok), I get:

System.ExecutionEngineException: Attempting to JIT compile method 'Steema.TeeChart.Styles.SeriesCollection:.ctor (Steema.TeeChart.Chart)' while running with --aot-only. See http://docs.xamarin.com/ios/about/limitations for more information.

How can this be corrected? I'm using latest Xamarin Studio, Xamarin.iOS, Mono framework and MacOS 10.8.3. The only difference between this version and the on in components page at Xamarin Component website is the version number. I don't know if the version available there has some correction or not, because this version isn't available at Steema download page.

Thanks,

Karl

Hello Karl,

I recommend you download the last version of TeeChartMonoTouch in our customer download page using your codes, because we incorporated some changes to solve the problem appears for you. When you have installed newest version please, try again if your problem persist.
If you have any problems please let my know.

Thanks,

Hi Sandra. Thanks for your answer.

To avoid mistakes, I deleted all versions that I tried and downloaded the last version as you suggested. Then when trying to compile a realease version for iPad, the following error message appear:

error MT2002: Failed to resolve "System.Boolean System.Type::op_Inequality(System.Type,System.Type)" reference from "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"

That is the same problem. If I compile it with "no link" then it compiles but fails at execution time with the message in earlier post.

Hi Karl,

I think this error appears if you don't have any "Deployment target" assigned to the project.
Try to go to project -> options -> iOS Application -> Summary and set one deployment target, "3.1" for example.

Are you ble to run the TChartFeatures demo (included into the installer) ? I've been doing some tests here and all is working fine (simulator and device) having as "Linker behaviour" to "link sdk assemblies only".

Please let me know if you still having problems and we'll try to find how to fix it.

Hi Pep.

Looking that configurations it is configured to 4.3. I tried now: 5.0, 5.1, 6.0, 6.1, 4.0, 3.1 and without it. All of them with the same error message.

I tried some samples while developing on MonoDevelop but just in simulator. It compiled and executed ok.

Now I tried TChartFeatures demo (to try to compile I did things like upgrade from MacOS 10,7 to 10,8, MonoDevelop to Xamarin Studio), on simulator it compiled but shown a message:
Cannot execute "[path for application]"

On device it doesn't compiled, with same message:
error MT2002: Failed to resolve "System.Boolean System.Type::op_Inequality(System.Type,System.Type)" reference from "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"

Hi Karl,

ok, I'm going to test the installer again with a clean installation and let you know something. In meantime you could get an alder installer, available at the customer download page.

About don't run in simulator it was uTorrent conflicting with Xamarin Studio... Closing it let Xamarin Studio to open simulator and run samples (and my apps).

Making some tests again (since here was a bit confusing on what things were made and tested on MonoDevelop or on Xamarin Studio...)

When running my app with SDK Assemblies Only on Simulator, it's not compiling, with a message:
error MT2002: Failed to resolve "System.Boolean System.Type::op_Inequality(System.Type,System.Type)" reference from "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"

When running with "dont' link", it run but when it founds a "chart.Series.Add (bar1);" it causes an exception:
Method not found: 'System.Type.op_Equality'.

Now running TChartFeatures demo:
- With Don't Link: Compile and run but when "tap" on the first option on menu on line 64 of ChartViewController.xib.cs (chart.Series.Add(series1);) it causes an exception:
Method not found: 'System.Type.op_Equality'.
- With Link SDK Assemblies only: Fails on compilation:
error MT2002: Failed to resolve "System.Boolean System.Type::op_Inequality(System.Type,System.Type)" reference from "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"

The last thing I see on status in top of Xamarin Studio screen is:
Compiling to native code
Building solution TChartFeatures (the error appear here)

The app I'm working on was made on MonoDevelop with old versions of everything. Only TeeChart I succeed to run on weeks ago while developing was on of june/2012 if I'm not mistaking something. But since I changed everything to last versions, that's the actual status of what's happening here. Changed everything because all was made on simulator and to compile to device it failed. Then I upgraded everything.

Hi Karl,

I've been doing some tests here, using the installer available on our web site, and all worked fine here.
I remember to see get this error message time ago moving from MonoDevelop to Xamarin Studio, upgrading projects...
About the "link behaviour" I suggest you left as "Link SDK assemblies only".

Which Xamarin.iOS version are you using ?
Have you tried to create a clean and new project, and then reference to the TeeChart.iOS library ?
Does it compile and work on simulator and device ? And removing the reference ?

If we still having problem I can compile another dll and send it to you so you can test with it. But first of all we should make sure the problem comes from our library.

Thanks !

For now:

I remember to see get this error message time ago moving from MonoDevelop to Xamarin Studio, upgrading projects...

Well, this was created with MonoDevelop with a version from 2012 I think.

Which Xamarin.iOS version are you using ?

Have you tried to create a clean and new project, and then reference to the TeeChart.iOS library ?
Does it compile and work on simulator and device ? And removing the reference ?

Not yet, will try today.

If we still having problem I can compile another dll and send it to you so you can test with it. But first of all we should make sure the problem comes from our library.

Ok, thanks

Karl

Hi Pep,

I created a new project "Single View" for iPad.
Compiled as it came to the world and run.
Add reference to the TeeChart.iOS.dll from folder TeeChartNETMonoTouch_v4_13_04_05 and run ok.

Then I altered ViewDidLoad() with that:
And run. The error occurred again exactly on "chart.Series.Add (bar1);" like demo and my app:
Method not found: 'System.Type.op_Equality'.

Karl

Hi Karl,

it's a strange behaviour.

Could you please try to download again the latest TeeChart for Xamarin.iOS from our web site and try (just to test the file is not corrupted) and try it again.
In the case the proble still there I will send a private message with the .dll I'm using.

Hi Pep.

I noticed that you are using beta version of Mono 3.0.10 and I'm on stable 2.10.12. This could be important. Also you're with Xamarin.iOS 6.3.4.36 and I with 6.2.4.2 (downloaded today).

Is there a possibility for you to try with Mono 2.10.12? HEre I just have one Mac.. so I don't know if I can go to beta Mono 3 to try without compromise production things...

Thanks,

Karl

Hi Karl,

ok, I'll give a try on another machine with the Mono 2.10.12.
The Xamarin version shouldn't be a problem, as I did tests before the update and all was working fine.
I'll let you know the results tomorrow, as I don't have another machine here.
Have you tried to download it again ? just to be sure that is the last update and that we're using the same files.

Hi Kark,

finally, I've been able to reproduce the problem ! As you said the Mono version seems to be very relevant. As the TeeChart library have been compiled with the latest beta version of Mono, this makes to appear that error.
I'm going to update the installers on out web site. Meanwhile I'm going to send to you directly the new dll as you can continue you work.

Thanks, and apologies for the wasted time with the tests.

Karl,

just let you know that I've updated the installers on our web site. Please download the same version again, which comes with the new compiled dll.
