Error compiling first Arduino project...

Hi Folks!
This is my first Visual Mictro 6.1 Project:
I do have a Visual Micro 6.1 and want to use it instead of the original Arduino IDE v1.61

When I open a Arduino *.ino file and compile it I get the following error:

Error      1      undefined reference to `main'      c:/program files (x86)/atmel/atmel toolchain/avr8 lib/avr6/crtm2560.o      1      1      Bewaesserungssteuerung
Error      2      ld returned 1 exit status      collect2.exe      0      0      Bewaesserungssteuerung

The original Arduino Project compiles and works fine!
I have not changed anything in the original *.ino file before compiling it in VM 6.1.

What is wrong?

JL

Hi,

Few questions please.

Please show a screen shot with the project loaded.

What is in the "Micro Build" output window after compile?

Thanks

Hi!
The screenshot is attached as compressed file as thee original BMP file was too large.

It includes the Output window.

Hi,

Okay I see you are using atmel studio. please close the project properties we do not use them for arduino compile.

To avoid confusion please also close the intellisense/error/warning list because it hides the Visual Micro build output which is what we need to see.

Please click "Build>Build Solution" then post the "Micro Build" output that should automatically appear. 

Thanks

I guess this is the Output you are looking for:

------ Erstellen gestartet: Projekt: Bewaesserungssteuerung, Konfiguration: Debug AVR ------
Der Buildvorgang wurde gestartet.
Projekt "Bewaesserungssteuerung.cppproj" (Standardziele):
Erstellung mit der Toolsversion 2.0.
Das Ziel "PreBuildEvent" wurde übersprungen, da die Bedingung "false" war . ('$(PreBuildEvent)'!='') wurde als (''!='') ausgewertet.

Die Erstellung des Projekts "Bewaesserungssteuerung.cppproj" ist abgeschlossen -- FEHLER.

Fehler beim Erstellen
========== Build: 0 erfolgreich oder aktuell, Fehler bei 1, 0 übersprungen ==========

It is in German.
Essentially it says:
PreBuildEvent is skipped...

The errorlist window says:
1) undefined reference to main file: crtm2560.o
2) Id returned 1 Exit Status file: collect2.exe


The Project was initially named Ethernet1 in Arduino IDE (it still has the name ethernet1.ino)
The Projectname given in VM 6.1. is Bewaesserungssteuerung"
Does this make a Problem?

Hi,

Thanks for the info.

Yes the project name is very important. It must be the same as the [master].ino which will also be the same name as the folder.

I think the output you are seeing is because Visual Micro is no longer managing the project. So atmel studio is attempting a standard compile.

If you rename the project to be Ethernet1.ino it should start to work and you should see a different build output.

If you are unsure then please follow the first steps to create a new project as a test example

Thanks

Hi!
Thanks so far!

The err is gone after I created a new VM Project with the Bewaesserungssteuerung Name.
(I copied and renamed then the old Ethernet1 file, replacing the inital ino file just created from VM).

I got now a msg in the Output window after compiling:
--------------
System.IO.FileLoadException: Die Datei oder Assembly "Atmel.Studio.Services.Interfaces, Version=6.2.0.0, Culture=neutral, PublicKeyToken=d264112969646cc9" oder eine Abhängigkeit davon wurde nicht gefunden. Die gefundene Manifestdefinition der Assembly stimmt nicht mit dem Assemblyverweis überein. (Ausnahme von HRESULT: 0x80131040)
Dateiname: 'Atmel.Studio.Services.Interfaces, Version=6.2.0.0, Culture=neutral, PublicKeyToken=d264112969646cc9'
   bei Visual.Micro.Visual.Studio.Arduino.AddInApp.CompileDo(Project oProject, Boolean IsDebugStartCommand)
   bei Visual.Micro.Visual.Studio.Arduino.AddInApp.Compile(Project oProject, Boolean IsDebugStartCommand)

WRN: Protokollierung der Assemblybindung ist AUS.
Sie können die Protokollierung der Assemblybindungsfehler aktivieren, indem Sie den Registrierungswert [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) auf 1 festlegen.
Hinweis: Die Protokollierung der Assemblybindungsfehler führt zu einer gewissen Leistungseinbuße.
Sie können diese Funktion deaktivieren, indem Sie den Registrierungswert [HKLM\Software\Microsoft\Fusion!EnableLog] entfernen.
--------------

Essentially it raises an exception:
System.IO.FileLoadException: File or Assembly "Atmel.Studio.Services.Interfaces .. or a dependancy not found

Could this be raised because I have no arduino board actualy connected or does it mean other Problems?

JL

Hi, Atmel changed some things last year when they released 6.2 so we had to stop supporting 6.1. Sorry this wasn't clear bit 6.2 is free and supported

Thanks for your patience

If you install 6.2 then you must run the vm installer after. Click uninstall then run again and click install

OK Tim!

I am just downloading v6.2sp2

Do I Need to uninstall my old Version before or does the installer handle it by itself?

Uninstall and reinstall after you have installed and run Atmel studio once
