Cosmos: Error occured while invoking IL2CPU... Impossible to find the assembly "System.Core"... [HELP]

[gael12334]

Sorry my computer is set in french...

I currently have the latest version of Cosmos (userkit-20170620);
I run Visual Studio 2017;
I remaked the whole project (VS2015) to put it on VS2017...
(i made new project with the same namespace and i only copied the .cs file)

The problem is I try to make a build but the compiler keep making the same error...

[jp2masa]

There's a more detailed description of the error in the output window.

[gael12334]

output

[jp2masa]

It seems that the compiler can't find the assembly generated by a referenced project. It never compiled with the latest user kit?

[gael12334]

well, i downloaded VS2017 yesturday, so basically no.... it never complied with the laest userkit...

[jp2masa]

This is probably a bug in the compiler, I'll check it.

LeafKernel.zip

Here's my OS / visual studio project (solution)
The start up project is called LeafKernel

[jp2masa]

This issue occurs when a method from a referenced project is used. I don't know why it's happening, because all the project references are compiled to assemblies that are copied to the project output path, so it should be loaded, but it throws an exception instead, because the assembly is not being found.

J'ai parfois la même erreur. Cela arrive si tu utilises des fonctions qui ne sont pas supporté par Cosmos et que le compilateur ne peut exécuté, par exemple j'ai tenté d'encoder là console en utf-8 pour avoir les accents de la langue française... J'avais l'avertissement aussi et cela ne m'a pas empêcher de continuer... (Je suis passé à devkit) Je te conseille d'utiliser le devkit qui est selon moi beaucoup mieux car tu auras les dernières résolutions de bugs.

Sometimes I have the same error. It's happens when you use fonctions that cosmos doesn't support yet and the compiler can't execute. For example, tried to encode the console in utf8 (for French accent), that is not supported by cosmos so I have this error. And for the advert, I have it too but we can continue to work, I think I don't have it on devkit.

[gael12334]

[gael12334]

thanks

[gael12334]

hum geomtech... the devkit is.... it is not helping alot.... i only see errors in visual studio

[zarlo]

was the project made with VS2015

[gael12334]

Yes, but I remade it to make it work in VS2017...
yet, its not working ....

[gael12334]

Well... i can't use the devkit... (im only 16...) because i cant even build the project...
And I re-tried to build my system on userkit-20170620... and still not working...

[zarlo]

do you have:
Visual Studio 2017 Workloads: .NET Core Tools and Visual Studio Extension Development
.NET Framework 4.6.2
InnoSetup with the free Preprocessor Add-on
VMWare Player and/or Bochs

[gael12334]

yes, zarlo
i do have all these
im re-installing the devkit to show it...

[gael12334]

when the latest devkit has finished to be installed, a project open itself....

[DjAlEx234]

@gael12334 , that is normal, the setup opens the cosmos sln file (after installing)

[gael12334]

i know, but im not a professional programmer... So what am i supposed to do with the cosmos project... all i want for now is being able to build my OS...

[fanoI]

Nothing you can close it :-)
You have to create a new C# project and between the possible templates you will get "Cosmos" and inside "C# Operating System" and you are ready to go...

[geomtech]

@gael12334 Si tu as des erreurs après l'installation de devkit, c'est normal, j'avais le même problème, il faut supprimer les références de Cosmos dans ton csproj et recharger les packages NuGet, sinon tu changes juste les versions de Cosmos au lieu de supprimer les références comme ça:

<ItemGroup> <PackageReference Include="Cosmos.Debug.Kernel" Version="1.0.*" /> <PackageReference Include="Cosmos.System" Version="1.0.*" /> </ItemGroup>

En:

[geomtech]

<ItemGroup> <PackageReference Include="Cosmos.Debug.Kernel" Version="1.0.2-*" /> <PackageReference Include="Cosmos.System" Version="1.0.2-*" /> </ItemGroup>

[gael12334]

Merci goemtech

[gael12334]

Still having the same issue (and more) on the devkit

[jp2masa]

It's a bug, I'm working on fixing it now.

[jp2masa]

It should be working now.

[geomtech]

@jp2masa we have to update the devkit ?

[jp2masa]

Yes.

[gael12334]

@jp2masa Your devkit installator has some errors...

btw, "à" means "at"
"Ligne" means "line"

[jp2masa]

What's the error?

[gael12334]

1: The name "RegisterSize" does not exsits in the actual context.[C:...\Cosmos.IL2CPU.csproj] (CosmosAssembler.cs (196,114): error CS0103)

2: Information for the project not found for "/.../Cosmos.Assembler.csproj". This can indicate a missing project reference . [C:...\IL2CPU.csproj]

3: Information for the project not found for "/.../Cosmos.Assembler.csproj". This can indicate a missing project reference . [C:...\Cosmos.Core_Asm.csproj]

[jp2masa]

I'll fix it.

[gael12334]

@jp2masa I have edited the comment

[jp2masa]

It should be working now.

[gael12334]

@jp2masa @geomtech

namespace "Cosmos" not found...

[jp2masa]

You need to restore nuget packages.

[gael12334]

@jp2masa oh ok thanks

[geomtech]

Regarde les références de ton projet si après la restauration des packages nuGet ça ne marche tjrs pas.

[gael12334]

how do i make "hardware" be in HAL?

[jp2masa]

It should be in System, or you can't use it from the kernel project. You need to add AssemblyInfo.cs with the Ring attribute (which can be found in Cosmos.Common).

[gael12334]

@jp2masa I put [assembly: Ring(Ring.System)], but the compiler seem to dont give a f* about the assemblyinfo.cs...

[jp2masa]

Are you getting the same error?

[gael12334]

@jp2masa

well... now the problem is about the rings...

[jp2masa]

Where did you add AssemblyInfo?

[gael12334]

@jp2masa i selected it in the solution explorer in my screenshot

[gael12334]

heres the assemblyinfo.cs

[jp2masa]

Try building the solution.

[gael12334]

@jp2masa it failed, it always does the same error

[gael12334]

@jp2masa i think it is the compiler that has a bug

[mterwoord]

You have your references incorrect. You know how Rings work?

[gael12334]

@mterwoord yes, but i cant change them..­.

hI?
