# Building open source software from source code is always interesting
# although time consuming at times.

# Make sure that your system has CMake, Ninja, GCC (c, c++) compiler, Python 3 installed.
# see https://github.com/ziglang/zig-bootstrap#host-system-dependencies

cd $HOME
mkdir ziglang
cd ziglang

# one of the ways to build zig is via zig-bootstrap
# it is time consuming, but interesting if you want to
# deepdive later into it.

git clone https://github.com/ziglang/zig-bootstrap
cd zig-bootstrap
# lets use Ninja for parallel builds to save time
export CMAKE_GENERATOR=Ninja
# I am using a 64-bit Ubuntu using intel CPU (AMD would work same).
# <arch> = x86_64
# <os> = linux
# <abi> = gnu
# <mcpu> = baseline
./build x86_64-linux-gnu baseline
# setup environment variable before building zig
