KFS (Kernel From Scratch)
This project aims to explore how a kernel works by building our own, gaining hands-on experience with core concepts like memory management, interrupt, keyboard driver, etc
INSTALLATION
Cross compile the compile
- install requirement follow THE DOCUMENTATION
- Setup the shell
export PREFIX="$HOME/opt/cross"
export TARGET=i386-elf
export PATH="$PREFIX/bin:$PATH"
mkdir $HOME/src
cd $HOME/src
tar xf [your binutils archive]
tar xf [your gcc archive]
tar xf [your gdb archive]
- (protips use -j [nb core])
- Compile binutils
cd $HOME/src
mkdir build-binutils
cd build-binutils
../binutils-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot --disable-nls --disable-werror
make
make install
- Compile gdb
cd $HOME/src
mkdir build-gdb
cd build-gdb
../gdb.x.y.z/configure --target=$TARGET --prefix="$PREFIX" --disable-werror
make all-gdb
make install-gdb
make
make install
- Compile gcc
cd $HOME/src
# The $PREFIX/bin dir _must_ be in the PATH. We did that above.
which -- $TARGET-as || echo $TARGET-as is not in the PATH
mkdir build-gcc
cd build-gcc
../gcc-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++ --without-headers
make all-gcc
make all-target-libgcc
make install-gcc
make install-target-libgcc
Compile and the start the kernel
make run
