Remove the `ZiglingStep.eval` method and the src/ipc.zig source code.
Use `Step.evalZigProcess`, instead. This greatly simplifies the code.
Print the error messages and error bundle in `ZiglingStep.make`, both in
case of error and success.
Additionally, remove the `ZiglingStep.is_testing` field, since it is no
longer necessary.
Currently addExecutable is called 3 times, unnecessarily making the code
more complex.
The method takes as argument the path to the exercises directory.
Additionally, use the new std.Build.ExecutableOptions.link_libc field.
The new field was added in ziglang/zig@adc9b77d5f on 2023-04-13.
Update the required Zig compiler version.
Note that I added the **current** zig version to the changelog, since
the reason for the change is known only to the person updating the
version.
Commit e214c44 (build: update ZiglingStep to the new API) broke again
the compatibility support for old compilers, due to the use of the
multi-object for loop syntax.
Move the Zig IPC support code to src/ipc.zig.
Use the while statement, instead of the for statement.
Update the code to the breaking change in ziglang commit
60eabc0ec (std.Build.CompileStep: remove run() and install())
Update the zig version in the README.md file.
The version check for Zig 0.6.0 was incorrect since commit
971ab7f (Use a zig build script to run ziglings).
Move compatibility support to a separate file, in order to simplify
build.zig.
In case of incompatible version, exit with code 3 instead of 0, in order
to detect the case of failure in a test (to be implemented).
Remove the use of comptime when checking compatibility at the start of
the build function, since it is not necessary.
Closes#210.
