* Cross-compiling is a primary use case.
|
||||
* In addition to creating executables, creating a C library is a primary use
|
||||
case. You can export an auto-generated .h file.
|
||||
* Standard library supports Operating System abstractions for:
|
||||
* `x86_64` `linux`
|
||||
* `x86_64` `macos`
|
||||
* Support for all popular operating systems and architectures is planned.
|
||||
* For OS development, Zig supports all architectures that LLVM does. All the
|
||||
standard library that does not depend on an OS is available to you in
|
||||
freestanding mode.
|
||||
|
||||
### Support Table
|
||||
|
||||
Freestanding means that you do not directly interact with the OS
|
||||
or you are writing your own OS.
|
||||
|
||||
Note that if you use libc or other libraries to interact with the OS,
|
||||
that counts as "freestanding" for the purposes of this table.
