# Building
|
|
### Environment
|
|
Linux distribution / Bash for Windows.
|
|
|
|
### Required packages
|
|
|
|
NASM (sudo apt-get install nasm)
|
|
|
|
GCC cross compiler (see the next section)
|
|
|
|
### GCC cross compiler
|
|
##### Method 1 - Compile from GCC source.
|
|
|
|
Follow the instructions from https://wiki.osdev.org/GCC_Cross-Compiler
|
|
|
|
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
|
|
|
|
1. Download "cross.tar.gz" from the Github release page.
|
|
|
|
2. Run "tar -xvf cross.tar.gz -C $HOME/opt/cross"
|
|
|
|
### Compiling
|
|
Run "make all" in the root directory
|
|
|
|
The makefile generates secxkrnl.elf(kernel executable), secxkrnl.dmp(kernel disassembly).
|
|
|
|
To clean all generated files, run "make clean"
