Zig supports generating code for all targets that LLVM supports. Here is
|
||||
what it looks like to execute <code>zig targets</code> on a Linux x86_64
|
||||
computer:
|
||||
<strong>Target</strong> refers to the computer that will be used to run an executable.
|
||||
It is composed of the CPU architecture, the set of enabled CPU features, operating system,
|
||||
minimum and maximum operating system version, ABI, and ABI version.

The Zig Standard Library ({#syntax#}@import("std"){#endsyntax#}) has architecture, environment, and operating system
|
||||
abstractions, and thus takes additional work to support more platforms.
|
||||
Not all standard library code requires operating system abstractions, however,
|
||||
so things such as generic data structures work on all above platforms.
|
||||
Zig is a general-purpose programming language which means that it is designed to
|
||||
generate optimal code for a large set of targets. The command <code>zig targets</code>
|
||||
provides information about all of the targets the compiler is aware of.</p>
|
||||
<p>When no target option is provided to the compiler, the default choice
|
||||
is to target the <strong>host computer</strong>, meaning that the
|
||||
resulting executable will be <em>unsuitable for copying to a different
|
||||
computer</em>. In order to copy an executable to another computer, the compiler
|
||||
needs to know about the target requirements via the <code>-target</code> option.
|
||||
</p>
|
||||
<p>
|
||||
The Zig Standard Library ({#syntax#}@import("std"){#endsyntax#}) has
|
||||
cross-platform abstractions, making the same source code viable on many targets.
|
||||
Some code is more portable than other code. In general, Zig code is extremely
|
||||
portable compared to other programming languages.
|
||||
</p>
|
||||
<p>
|
||||
Each platform requires its own implementations to make Zig's
|
||||
cross-platform abstractions work. These implementations are at various
|
||||
degrees of completion. Each tagged release of the compiler comes with
|
||||
release notes that provide the full support table for each target.
|
||||
</p>
|
||||
<p>The current list of targets supported by the Zig Standard Library is:</p>
|
||||
<ul>
|
||||
<li>Linux x86_64</li>
|
||||
<li>Windows x86_64</li>
|
||||
<li>macOS x86_64</li>
|
||||
</ul>
