Building the MOP3 kernel

This article describes, how to build the kernel, how the build system works and prerequisites.

Preprequistes

• POSIX host system (tested on Linux, may break on other systems)
• Git
• GNU make
• LLVM toolchain/Clang C compiler
• Xorriso

Build steps

cd into root of MOP3 source tree.

Build the kernel:

make -B all_kernel buildtype=<debug|release>

Build essential system applications:

make -B all_apps

Prepare the ramdisk:

make -B all_dist

Build ISO image:

./aux/limine_iso_amd64.sh

Now you have an ISO image, which can be run my QEMU or you can burn it onto a CD.

For the convenience of the developer, there's a magic "do all" script located in aux:

./aux/devel.sh # optionally "./aux/devel.sh debug" for debugging

It does all the previous steps, just packed into a single script.
