My Hobby x86-64 OS kernel.
Building
Environment
Any Linux distribution / Bash for Windows + GCC cross compiler.
Required packages
To compile the kernel, the following modules are required on linux system, please install these:
nasm, xorriso, grub-common, grub-pc-bin
Cross-compiler
Method 1 - Compile one yourself.
Just follow the instructions here: https://wiki.osdev.org/GCC_Cross-Compiler
Remember to set the "TARGET" to x86_64-elf instead of i686-elf and build libgcc without redzone https://wiki.osdev.org/Libgcc_without_red_zone.
Method 2 - Precompiled binaries
Here is my precompiled cross compiler. Feel free to use it.
VERSION: GCC 7.3 + Binutils 2.30
HOST: x86_64-pc-linux-gnu
CONFIGURED WITH: --target=x86_64-elf --disable-nls --enable-languages=c,c++ --without-headers
-
Download "cross.tar.gz" from the release page.
-
Run "tar -xvf cross.tar.gz -C $HOME/opt/cross"
Compiling
Run "make all" in the root directory
The makefile generates secxkrnl.iso (kernel image), secxkrnl.elf(kernel executable), secxkrnl.dmp(kernel disassembly) at the end.
To clean all generated files, run "make clean"
Running
On windows run "qemu.bat"
On linux run "./qemu.bat"
