All platforms where the required packages are available.
### Required packages
nasm, clang (6.0+), make
For compiling kernel only (make compile):
nasm, clang, lld, llvm
To make bootable ISO (make all):
xorriso; grub-pc-bin for bios; grub-efi-amd64-bin, mtools for UEFI.
### Compiling
Run "make" in the root directory.
Run "make all" or "make compile" in the root directory.
This will generate secxkrnl.elf (kernel executable) and secxkrnl.dmp (kernel dump).
This will generate secxkrnl.elf, secxkrnl.dmp, (and secxkrnl.iso) in "out" folder
Run "make clean" to clean a build.
# Running
secX requires bootloader [secboot](https://github.com/secXsQuared/secboot).
See secboot repository for more information.
# Running
Load the iso with your favorite simulator or use "-kernel" option with QEMU.
For UEFI simulation, use qemu_bios.bin in the root dir with QEMU.
