Cannot build kgdboe with kernel 4.15.0-36-generic

[PhilCornet]

Hi,

 

I am trying to debug a module with ViualKernel 3.0 (build 2166) through ethernet but encounter an error during the build of kgdboe.

The target platform runs kernel 4.15.0-36-generic.

It seems that the version of kgdboe that VisualKernel is trying to build still uses “init_timer” which was removed from kernel 4.15…

Is there a way to update the version of kgdboe used by Visual Kernel?

Thanks.

Hi,

Sorry, we haven’t tested kgdboe with this kernel version yet. We will run the tests on it, patch it and update the version installed by VisualKernel in the next few months.

If the fix is trivial and you don’t want to wait for an official update from us, you can simply fork our Github repo, patch the code and replace the files in %LOCALAPPDATA%\VisualGDB\VisualKernel\KernelPackages\kgdboe.
