C-Zig

Just a simple example of how to use Zig compiler to compile adder.c and main.zig file that includes a C header file called adder.h. Read the build.sh file to learn more.

Build

Just run the build.sh script.

./build.sh

Why a build script?

Zig is capable of compiling C source code. But the problem is Zig compiler needs to know where to find C headers (aka. Include directories like /usr/include). In the command line you can literally do this in project's root directory:

zig build-exe -I. adder.c main.zig

Zig compiler will compile both C and Zig source files into a single executable!

Here, I just included adder.h file in main.zig. So technically I just need to add the current directory ./ to be searched for header files. So like C compilers we can use -I flag to add a directory to be searched for header files by zig compiler (-I.). Then Zig compiler can find adder.h.

In case you want to use libc (like stdio.h) you need to find and add system include directories with -I flag. Then you have to link the final executable against libc with -lc flag passed to zig compiler. So I created build.sh as an example for that.

Note that I didn't initialized any zig project with zig init command. If you are created a Zig project all of the things above can be declared in the build.zig file.
