This list of supported platforms is current as of the branch / release to

which it is attached.

Node.js relies on V8 and libuv. Therefore, we adopt a subset of their

supported platforms.

Support is divided into three tiers:

* **Tier 1**: Full test coverage and maintenance by the Node.js core team and

the broader community.

* **Tier 2**: Full test coverage but more limited maintenance,

often provided by the vendor of the platform.

* **Experimental**: Known to compile but not necessarily reliably or with

a full passing test suite. These are often working to be promoted to Tier

2 but are not quite ready. There is at least one individual actively

providing maintenance and the team is striving to broaden quality and

reliability of support.

| System | Support type | Version | Architectures | Notes |

|--------------|--------------|----------------------------------|----------------------|------------------|

| GNU/Linux | Tier 1 | kernel >= 2.6.18, glibc >= 2.5 | x86, x64, arm, arm64 | |

| macOS | Tier 1 | >= 10.10 | x64 | |

| Windows | Tier 1 | >= Windows 7 or >= Windows2008R2 | x86, x64 | |

| SmartOS | Tier 2 | >= 15 < 16.4 | x86, x64 | see note1 |

| FreeBSD | Tier 2 | >= 10 | x64 | |

| GNU/Linux | Tier 2 | kernel >= 4.2.0, glibc >= 2.19 | ppc64be | |

| GNU/Linux | Tier 2 | kernel >= 3.13.0, glibc >= 2.19 | ppc64le | |

| AIX | Tier 2 | >= 6.1 TL09 | ppc64be | |

| GNU/Linux | Tier 2 | kernel >= 3.10, glibc >= 2.17 | s390x | |

| macOS | Experimental | >= 10.8 < 10.10 | x64 | no test coverage |

| Linux (musl) | Experimental | musl >= 1.0 | x64 | |

note1 - The gcc4.8-libs package needs to be installed, because node

binaries have been built with GCC 4.8, for which runtime libraries are not

installed by default. For these node versions, the recommended binaries

are the ones available in pkgsrc, not the one available from nodejs.org.

Note that the binaries downloaded from the pkgsrc repositories are not

officially supported by the Node.js project, and instead are supported

by Joyent. SmartOS images >= 16.4 are not supported because

GCC 4.8 runtime libraries are not available in their pkgsrc repository

Depending on host platform, the selection of toolchains may vary.

* GCC 4.8.5 or newer

* Clang 3.4.1 or newer

* Building Node: Visual Studio 2015 or Visual C++ Build Tools 2015 or newer

* Building native add-ons: Visual Studio 2013 or Visual C++ Build Tools 2015

or newer

On OS X, you will also need:

* [Xcode](https://developer.apple.com/xcode/download/)

- You also need to install the `Command Line Tools` via Xcode. You can find

this under the menu `Xcode -> Preferences -> Downloads`

- This step will install `gcc` and the related toolchain containing `make`

* After building, you may want to setup [firewall rules](tools/macosx-firewall.sh)

to avoid popups asking to accept incoming network connections when running tests:

[GNU Make Documentation](https://www.gnu.org/software/make/manual/html_node/Parallel.html)

for more information.

Note that the above requires that `python` resolve to Python 2.6 or 2.7

and not a newer version.

To run the tests:

**Note**: building in this way does **not** allow you to claim that the

runtime is FIPS 140-2 validated. Instead you can indicate that the runtime

uses a validated module. See the

[security policy](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf)

page 60 for more details. In addition, the validation for the underlying module

is only valid if it is deployed in accordance with its

[security policy](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf).

If you need FIPS validated cryptography it is recommended that you read both

the [security policy](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf)

and [user guide](https://openssl.org/docs/fips/UserGuide-2.0.pdf).
