App built on Linux does not run on windows

[JanezStupar]

Here is the deal. About a week ago I tried out hover as an alternative build process to the project built in for its advanced packaging support.

The initial test on my app seemed to work well enough, so I started figuring out how to add DLL's and how to handle the plugins I need as app installed on systems with installed VS redist package.

But then I never got to run the result on windows again. I assumed that something is wrong with dependencies until two days ago I decided to step back again and to confirm that tooling works as expected. For the record I am installing app on a virtual machine.

To this end I created a new flutter app using flutter create simple

See the logs below.

What are the symptoms you are seeing?

The MSI installer works fine. The application gets successfully installed. But it doesn't run. There is no log entry visible through event viewer. There is no console output when running from cmd, I tried added logging into the dart main method but it seems that the executable doesn't get that far either. The linux build works fine.

So I am a bit lost here, because "it doesn't work" is all I can offer.

So as a first step, I would need some guidance to help me gather more information.

@pchampio @jld3103 @GeertJohan can somebody please give me some pointers how to collect more information?

[provokateurin]

Oh I wrote an answer but it somehow disappeard. Sorry for that.
I wrote something like this:

• Compile and run the app directly on windows
• Cross-compile and the run the app on windows (without packaging)

If something works or not it will be useful to debug it further.

[JanezStupar]

I have been busy elsewhere and I expect to provide required feedback in the next couple of days. I am still very much intereseted and invested in getting hover to work for my use case.

[JanezStupar]

Okay so I took some time to do the testing. Turns out that the build works very well. Even with develop channel.

Turns out the issue was that I was trying to run the app in VM. I expected that it will work since the official embedder does.

Feel free to close this issue.

You might be able to run it in a vm using: #272 (comment)

Hi I built the windows-msi package in UBuntu linux
I ran the installer in another windows machine I have , it got installed but the app didn't run
I got the same issue which @james-lawrence got , not in a vm but a real machine

How do I fix this?

[provokateurin]

Do you have any logs?

[TheSeriousProgrammer]

This is inside a VM , I ran a build cammand with opengl=none arguement , However it didnt work

@pchampio already said everything there is about running in a VM
