*** Colonel ***
|
|
===============
|
|
Colonel (pronounced as it is spelt) is a kernel project I'm working on in my
|
|
free time. As a personal project, you really shouldn't run it anywhere but in
|
|
an emulator. Currently the project supports the following architectures:
|
|
|
|
- x86
|
|
- i386
|
|
- i686
|
|
|
|
# Compiling
|
|
-----------
|
|
In order to compile this project you will require the following:
|
|
|
|
- GCC Cross-Compiler (https://gcc.gnu.org/)
|
|
- GNU Binutils (https://www.gnu.org/software/binutils/)
|
|
- CMake (https://cmake.org/)
|
|
|
|
You may want to compile GCC and Binutils from source for your target
|
|
architecture. You can find the available toolchains for building in the
|
|
`toolchains/' directory. To compile you can run the following commands:
|
|
|
|
cd build/
|
|
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchains/<toolchain_file> ..
|
|
make
|
|
|
|
This should create a release build of the project. If you would like debug
|
|
flags then add the `-DCMAKE_BUILD_TYPE=debug' option to the `cmake' command.
|
|
|
|
# Testing
|
|
---------
|
|
The safest environment to test this in would be an emulator. The one I use is
|
|
QEMU (https://www.qemu.org/). You can run the kernel directly (i.e.
|
|
`colonel.bin') by using the `-kernel' option. If you'd like to debug the kernel
|
|
using QEMU and GDB you can do so by running `qemu -S -s -kernel colonel.bin',
|
|
which will open a server on `localhost' allowing you to connect with GDB for
|
|
debugging. At this point you can connect to the server and load the symbols by
|
|
running the following in the GDB prompt:
|
|
|
|
(gdb) target remote localhost:1234
|
|
(gdb) symbol-file colonel.bin
|
|
|
|
From this point on you can use GDB to debug the kernel.
