## Building from Source
|
|
|
|
[](https://dev.azure.com/ziglang/zig/_build/latest?definitionId=1&branchName=master)
|
|
|
|
Note that you can
|
|
[download a binary of the master branch](https://ziglang.org/download/#release-master) or
|
|
[install Zig from a package manager](https://github.com/ziglang/zig/wiki/Install-Zig-from-a-Package-Manager).
|
|
|
|
### Stage 1: Build Zig from C++ Source Code
|
|
|
|
This step must be repeated when you make changes to any of the C++ source code.
|
|
|
|
#### Dependencies
|
|
|
|
##### POSIX
|
|
|
|
* cmake >= 2.8.5
|
|
* gcc >= 5.0.0 or clang >= 3.6.0
|
|
* LLVM, Clang, LLD development libraries == 11.x, compiled with the same gcc or clang version above
|
|
- Use the system package manager, or [build from source](https://github.com/ziglang/zig/wiki/How-to-build-LLVM,-libclang,-and-liblld-from-source#posix).
|
|
|
|
##### Windows
|
|
|
|
* cmake >= 3.15.3
|
|
* Microsoft Visual Studio. Supported versions:
|
|
- 2017 (version 15.8)
|
|
- 2019 (version 16)
|
|
* LLVM, Clang, LLD development libraries == 11.x
|
|
- Use the [pre-built binaries](https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows) or [build from source](https://github.com/ziglang/zig/wiki/How-to-build-LLVM,-libclang,-and-liblld-from-source#windows).
|
|
|
|
#### Instructions
|
|
|
|
##### POSIX
|
|
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
make install
|
|
```
|

|
|
|
|
##### MacOS
|
|
|
|
```
|
|
brew install cmake llvm
|
|
brew outdated llvm || brew upgrade llvm
|
|
mkdir build
|
|
cd build
|
|
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
|
|
make install
|
|
```
|
|
|
|
##### Windows
|
|
|
|
See https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows
|
|
|
|
### Stage 2: Build Self-Hosted Zig from Zig Source Code
|
|
|
|
Now we use the stage1 binary:
|
|
|
|
```
|
|
zig build --prefix $(pwd)/stage2 -Denable-llvm
|
|
```
|
|
|
|
This produces `stage2/bin/zig` which can be used for testing and development.
|
|
Once it is feature complete, it will be used to build stage 3 - the final compiler
|
|
binary.
|
|
|
|
### Stage 3: Rebuild Self-Hosted Zig Using the Self-Hosted Compiler
|
|
|
|
*Note: Stage 2 compiler is not yet able to build Stage 3. Building Stage 3 is
|
|
not yet supported.*
|
|
|
|
Once the self-hosted compiler can build itself, this will be the actual
|
|
compiler binary that we will install to the system. Until then, users should
|
|
use stage 1.
|
|
|
|
#### Debug / Development Build
|
|
|
|
```
|
|
stage2/bin/zig build
|
|
```
|
|
|
|
This produces `zig-cache/bin/zig`.
|
|
|
|
#### Release / Install Build
|
|
|
|
```
|
|
stage2/bin/zig build install -Drelease
|
|
```
|
|
|
|
## License
|
|
|
|
The ultimate goal of the Zig project is to serve users. As a first-order
|
|
effect, this means users of the compiler, helping programmers to write better
|
|
software. Even more important, however, are the end-users.
|
|
|
|
Zig is intended to be used to help **end-users** accomplish their goals. Zig
|
|
should be used to empower end-users, never to exploit them financially, or to
|
|
limit their freedom to interact with hardware or software in any way.
|
|
|
|
However, such problems are best solved with social norms, not with software
|
|
licenses. Any attempt to complicate the software license of Zig would risk
|
|
compromising the value Zig provides.
|
|
|
|
Therefore, Zig is available under the MIT (Expat) License, and comes with a
|
|
humble request: use it to make software better serve the needs of end-users.
|
|
|
|
This project redistributes code from other projects, some of which have other
|
|
licenses besides MIT. Such licenses are generally similar to the MIT license
|
|
for practical purposes. See the subdirectories and files inside lib/ for more
|
|
details.
