# The Odin Programming Language
## Setup
Odin only supports x86-64 at the moment (64-bit), relies on LLVM for code generation and an external linker.
In addition, the following platform-specific steps are necessary:
- Windows
* Have Visual Studio installed (MSVC 2010 or later, for the linker)
* Have a copy of `opt.exe` and `llc.exe` in `Odin/bin`. Pre-built Windows binaries can be found [here](https://github.com/odin-lang/Odin/releases/tag/llvm-windows) and *must* be explicitly copied
* Open a valid command prompt:
* **Basic:** run the `x64 Native Tools Command Prompt for VS2017` shortcut bundled with VS 2017, or
* **Advanced:** run `vcvarsall.bat x64` from a blank `cmd` session
- MacOS
* Have LLVM explicitly installed (`brew install llvm`)
* Have XCode installed (version X.X or later, for linking)
* Make sure the LLVM binaries and the linker are added to your `$PATH` environmental variable
- GNU/Linux
* Have LLVM installed (opt/llc)
* Have Clang installed (version X.X or later, for linking)
* Make sure the LLVM binaries and the linker are added to your `$PATH` environmental variable
Then build the compiler by calling `build.bat` (Windows) or `make` (Linux/MacOS). This will automatically run the demo program if successful.
**Notes for Linux:**: The compiler currently relies on the `core` and `shared` library collection being relative to the compiler executable. Installing the compiler in the usual sense (to `/usr/local/bin` or similar) is therefore not as straight forward as you need to make sure the mentioned libraries are available. As a result, it is recommended to simply explicitly invoke the compiler with `/path/to/odin` in your preferred build system, or add `/path/to/odin` to `$PATH`.
Please read the [Getting Started Guide](https://github.com/odin-lang/Odin/wiki#getting-started-with-odin) for more information.
