Building

BRUTAL can be built by using either LLVM or GNU toolchains.

In both cases you will need nasm and make.

On Arch Linux this can be done by doing pacman -S make nasm

Run git submodule update --init --recursive to install the submodules before building

With LLVM

Before trying to build BRUTAL with LLVM you need to install lld and clang-13.

On Arch Linux this can be done by doing pacman -S lld clang.

Build BRUTAL via the LLVM toolchain:

make all

On some distros you might want to change the llvm version using LLVM_VERSION=-13 or any other version.

With GNU

In order to build BRUTAL with the GNU toolchain you will need to build the x86_64-elf binutils. This can be done by running the script in build/toolchain/gnu/build.sh.

After building the binutils you can build BRUTAL by running:

make all TOOLCHAIN=gnu

On macOS

If you use Homebrew package manager, you can obtain the dependencies by running brew install qemu nasm xorriso llvm binutils wget pkg-config sdl2.

LLVM on Homebrew is keg by default, you also need to set the following environment variables:

export PATH="/usr/local/opt/llvm/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"

Then build BRUTAL by running:

make all

Note About Windows

Just switch to GNU+Linux
