## Compiling
The compiler currently officially supports the following platform and
architecture combinations:
* Windows (Windows XP or greater) - x86 and x86_64
* Linux (most, if not all, distributions) - x86, x86_64, ppc64 and armv6l
* Mac OS X (10.04 or greater) - x86, x86_64 and ppc64
More platforms are supported, however they are not tested regularly and they
may not be as stable as the above-listed platforms.
Compiling the Nim compiler is quite straightforward if you follow these steps:
First, the C source of an older version of the Nim compiler is needed to
bootstrap the latest version because the Nim compiler itself is written in the
Nim programming language. Those C sources are available within the
[``nim-lang/csources``][csources-repo] repository.
Next, to build from source you will need:
* A C compiler such as ``gcc`` 3.x/later or an alternative such as ``clang``,
``Visual C++`` or ``Intel C++``. It is recommended to use ``gcc`` 3.x or
later.
* Either ``git`` or ``wget`` to download the needed source repositories.
* The ``build-essential`` package when using ``gcc`` on Ubuntu (and likely
other distros as well).
* On Windows MinGW 4.3.0 (GCC 8.10) is the minimum recommended compiler.
* Nim hosts a known working MinGW distribution:
* [MinGW32.7z](https://nim-lang.org/download/mingw32.7z)
* [MinGW64.7z](https://nim-lang.org/download/mingw64.7z)
**Windows Note: Cygwin and similar posix runtime environments are not supported.**
Then, if you are on a \*nix system or Windows, the following steps should compile
Nim from source using ``gcc``, ``git`` and the ``koch`` build tool.
**Note: The following commands are for the development version of the compiler.**
For most users, installing the latest stable version is enough. Check out
the installation instructions on the website to do so: https://nim-lang.org/install.html.
For package maintainers: see [packaging guidelines](https://nim-lang.github.io/Nim/packaging.html).
First get Nim from github:
```
git clone https://github.com/nim-lang/Nim.git
cd Nim
```
Next run the appropriate build shell script for your platform:
* `build_all.sh` (Linux, Mac)
* `build_all.bat` (Windows)
Windows requires a number of other dependencies that you may need to install including
PCRE and OpenSSL. Nim hosts a zip package containing known working versions of the
required DLLs [here](https://nim-lang.org/download/dlls.zip).
Finally, once you have finished the build steps (on Windows, Mac or Linux) you
should add the ``bin`` directory to your PATH.
See also [rebuilding the compiler](doc/intern.rst#rebuilding-the-compiler).
## Koch
``koch`` is the build tool used to build various parts of Nim and to generate
documentation and the website, among other things. The ``koch`` tool can also
be used to run the Nim test suite.
Assuming that you added Nim's ``bin`` directory to your PATH, you may execute
the tests using ``./koch tests``. The tests take a while to run, but you
can run a subset of tests by specifying a category (for example
``./koch tests cat async``).
For more information on the ``koch`` build tool please see the documentation
within the [doc/koch.rst](doc/koch.rst) file.
## Nimble
``nimble`` is Nim's package manager. To learn more about it, see the
[``nim-lang/nimble``][nimble-repo] repository.
