My Hobby x86-64 OS kernel.
Building
Environment
Any Linux distribution / Bash for Windows + GCC cross compiler.
Required packages
Please use "sudo apt-get install" to install these:
nasm, xorriso, binutils-mingw-w64, gcc-mingw-w64, mtools
Cross-compiler
Method 1 - Compile 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
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 Github 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"
