Error occurred while invoking IL2CPU

[IanSteg]

I'm trying to build my OS but I keep getting the 'Error occurred while invoking IL2CPU.' I had this problem a couple of days ago with the problem being VS was in Release mode. I fixed this by putting it in Debug mode and now after I add some new things in the Kernel, I am getting the error again. I get the error on all build profiles.

Could you give us the full log.

Well you used a feature that isn't yet implemented.

[IanSteg]

Which is?

[mterwoord]

Mul_Ovf_Un opcode

[IanSteg]

I dont see where I used it... What does it do?

[mterwoord]

Mul_Ovf_Un is used for multiplying undefined numbers. Not sure on semantics.

On a side note: we have a gitter channel, where we have people around pretty much all day. Response times should be lower there.. :)

[IanSteg]

Ok, I still have no idea where I used it. Is there a way I can look for it? Could I just Ctrl+F to find it?

Response times are no problem for me. Thanks anyway. Good to know for when I have a time sensitive project.

[jp2masa]

I think that Mul_Ovf_Un is implemented in the devkit, there was an issue about that.

[fanoI]

Yes it is implemented: https://github.com/CosmosOS/Cosmos/blob/master/source/Cosmos.IL2CPU/IL/Mul_Ovf_Un.cs

@IanSteg are you sure you are using on the last devKit? However probably you not calling the Mul_Ovf_Un directly but some library you are using is doing this you can use ILSPY to see what is using it.

[IanSteg]

I am using the userkit... How do you use ILSPY?

[fanoI]

OK then first use the DevKit really a lot of things are been fixed... as you can see above now we have Mul_Ovf_Un now!

[IanSteg]

Ok, I'll give it a go.

[IanSteg]

Can you give me the link to the DevKit download?

[jp2masa]

The devkit is the version from the mastee branch, just clone it and run install-VS2015.bat

[fanoI]

There is no direct link to the devKit because is de facto the actual GitHub "snapshot" of the Cosmos source code. You have two way to grab it:

1. If you to contribute to Cosmos you should clone it in your GitHub account
2. You can download it as a zip file

You find this in the green button "Clone or Download" here: https://github.com/CosmosOS/Cosmos

Look here of how to install it: https://github.com/CosmosOS/Cosmos/wiki/Devkit

[IanSteg]

How do I know if it installed and I am using the DevKit version?

[jp2masa]

If the devkit installation is successful, Cosmos.sln will be opened in VS.

[fanoI]

Please be patient is really slow... could last until 15 minutes!

[IanSteg]

Yay! It works! Thanks everyone!
