Hi,
I have VisualKernel 4.1r3 and I want to test kernel module (Hello World based on Your extension plugin), but I see below error message

Command exited with code 2I use Ubuntu 24.04.1 and Visual Studio 2022
Another problem, that I want to know why below warning exists? any missing? How to resolve this warnings?
warning: no previous prototype for ‘LookupSymbolByName’ [-Wmissing-prototypes]Thanks 🙂
Thanks for reporting this. We will monitor the feedback from our paid users, and will consider investigating it further if they confirm it.
Why you need to confirm this problem by other? if you want any information or additional data, I can provide to you
Sorry, based on what we see, you do not have a valid license and tried tampering with the activation system. We will not be able to help you.
I also meet this issue in VisualKernel-4.1r3-trial.And i find that module_core and core_size members didn’t defined in module.h, But they existed in older kernel. How can i fix it ?or i buy VisualKernel with license that can fix these issues.
thank you!
Hi,
Unfortunately, we do not see enough demand for Visual Studio-based kernel development anymore. Many company users moved to developing from Linux directly, and hobbyists typically manage to get things done during the trial period, and cannot justify getting a license. Hence, we will only update VisualKernel once our new cross-platform IDE framework is mature enough to support kernel tracing and debugging directly on Linux.
If your team is interested in using VisualKernel with Visual Studio, feel free to contact us from your work email address with a brief description of your project and the features you are interested in, and we can discuss possible options.
