The 4.11.2 documentation is available from the web site. See and specifically:

My personal area is just what there is. It must be a search engine.

On Windows the RSB takes the first letter of each part to shorten the length of
the path. This means `ark41` is arm-rtems-kernel-4.11.

I suggest you try a build with `--without-rtems` on the command line. This will
not build RTEMS. You will then need to build RTEMS manually.

What was the architecture? Different architectures have a differing number of
libraries and this changes the time needed to build.

Also the RTEMS kernel building builds all BSPs and this arch has a lot of BSPs.
That would take a while.

Disabling virus protection will make things faster.

I will try a build and see if I get what you have reported below.
