Building and Running Project:
|
|
|
|
|
|
|
|
|
|
This microkernel project outputs to the console. It can be built and executed
|
|
|
|
|
on QEMU as follows:
|
|
|
|
|
|
2017-01-08 05:31:34 +08:00
|
|
|
make run
|

Troubleshooting:
|
|
|
|
|
|
|
|
|
|
Problems caused by out-dated project information can be addressed by
|
|
|
|
|
issuing one of the following commands then rebuilding the project:
|
|
|
|
|
|
|
|
|
|
make clean # discard results of previous builds
|
|
|
|
|
# but keep existing configuration info
|
|
|
|
|
or
|
|
|
|
|
make pristine # discard results of previous builds
|
|
|
|
|
# and restore pre-defined configuration info
|
|
|
|
