## Building from source
|
|
|
|
Below are instructions on how to build Deno from source. If you just want to use
|
|
Deno you can download a prebuilt executable (more information in the
|
|
`Getting Started` chapter).
|
|
|
|
### Cloning the Repository
|
|
|
|
Clone on Linux or Mac:
|
|
|
|
```shell
|
|
git clone --recurse-submodules https://github.com/denoland/deno.git
|
|
```
|
|
|
|
Extra steps for Windows users:
|
|
|
|
1. [Enable "Developer Mode"](https://www.google.com/search?q=windows+enable+developer+mode)
|
|
(otherwise symlinks would require administrator privileges).
|
|
2. Make sure you are using git version 2.19.2.windows.1 or newer.
|
|
3. Set `core.symlinks=true` before the checkout:
|
|
```shell
|
|
git config --global core.symlinks true
|
|
git clone --recurse-submodules https://github.com/denoland/deno.git
|
|
```
|
|
|
|
### Prerequisites
|
|
|
|
> Deno requires the progressively latest stable release of Rust. Deno does not
|
|
> support the Rust nightlies.
|
|
|
|
[Update or Install Rust](https://www.rust-lang.org/tools/install). Check that
|
|
Rust installed/updated correctly:
|
|
|
|
```
|
|
rustc -V
|
|
cargo -V
|
|
```
|
|
|
|
### Building Deno
|
|
|
|
The easiest way to build Deno is by using a precompiled version of V8:
|
|
|
|
```
|
|
cargo build -vv
|
|
```
|
|
|
|
However if you want to build Deno and V8 from source code:
|
|
|
|
```
|
|
V8_FROM_SOURCE=1 cargo build -vv
|
|
```
|
|
|
|
When building V8 from source, there are more dependencies:
|
|
|
|
[Python 2](https://www.python.org/downloads). Ensure that a suffix-less
|
|
`python`/`python.exe` exists in your `PATH` and it refers to Python 2,
|
|
[not 3](https://github.com/denoland/deno/issues/464#issuecomment-411795578).
|
|
|
|
For Linux users glib-2.0 development files must also be installed. (On Ubuntu,
|
|
run `apt install libglib2.0-dev`.)
|
|
|
|
Mac users must have Command Line Tools installed.
|
|
([XCode](https://developer.apple.com/xcode/) already includes CLT. Run
|
|
`xcode-select --install` to install it without XCode.)
|
|
|
|
For Windows users:
|
|
|
|
1. Get [VS Community 2019](https://www.visualstudio.com/downloads/) with
|
|
"Desktop development with C++" toolkit and make sure to select the following
|
|
required tools listed below along with all C++ tools.
|
|
|
|
- Visual C++ tools for CMake
|
|
- Windows 10 SDK (10.0.17763.0)
|
|
- Testing tools core features - Build Tools
|
|
- Visual C++ ATL for x86 and x64
|
|
- Visual C++ MFC for x86 and x64
|
|
- C++/CLI support
|
|
- VC++ 2015.3 v14.00 (v140) toolset for desktop
|
|
|
|
2. Enable "Debugging Tools for Windows". Go to "Control Panel" → "Programs" →
|
|
"Programs and Features" → Select "Windows Software Development Kit - Windows
|
|
10" → "Change" → "Change" → Check "Debugging Tools For Windows" → "Change" →
|
|
"Finish". Or use:
|
|
[Debugging Tools for Windows](https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/)
|
|
(Notice: it will download the files, you should install
|
|
`X64 Debuggers And Tools-x64_en-us.msi` file manually.)
|
|
|
|
See [rusty_v8's README](https://github.com/denoland/rusty_v8) for more details
|
|
about the V8 build.

|
|
### Building
|
|
|
|
Build with Cargo:
|
|
|
|
```shell
|
|
# Build:
|
|
cargo build -vv
|
|
|
|
# Build errors? Ensure you have latest main and try building again, or if that doesn't work try:
|
|
cargo clean && cargo build -vv
|
|
|
|
# Run:
|
|
./target/debug/deno run cli/tests/002_hello.ts
|
|
```
|
