<em id="fn1">1</em>: GCC 8 is not provided on the base platform. Users will

need the

[Toolchain test builds PPA](https://launchpad.net/\~ubuntu-toolchain-r/+archive/ubuntu/test?field.series\_filter=xenial)

or similar to source a newer compiler.

<em id="fn2">2</em>: GCC 8 is not provided on the base platform. Users will

need the

[devtoolset-8](https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/)

or later to source a newer compiler.

<em id="fn3">3</em>: Older kernel versions may work for ARM64. However the

Node.js test infrastructure only tests >= 4.5.

<em id="fn4">4</em>: On Windows, running Node.js in Windows terminal emulators

like `mintty` requires the usage of [winpty](https://github.com/rprichard/winpty)

for the tty channels to work (e.g. `winpty node.exe script.js`).

In "Git bash" if you call the node shell alias (`node` without the `.exe`

extension), `winpty` is used automatically.

<em id="fn5">5</em>: The Windows Subsystem for Linux (WSL) is not

supported, but the GNU/Linux build process and binaries should work. The

community will only address issues that reproduce on native GNU/Linux

systems. Issues that only reproduce on WSL should be reported in the

[WSL issue tracker](https://github.com/Microsoft/WSL/issues). Running the

Windows binary (`node.exe`) in WSL is not recommended. It will not work

without workarounds such as stdio redirection.

<em id="fn6">6</em>: Running Node.js on x86 Windows should work and binaries

are provided. However, tests in our infrastructure only run on WoW64.

Furthermore, compiling on x86 Windows is Experimental and

may not be possible.

<em id="fn7">7</em>: The default FreeBSD 12.0 compiler is Clang 6.0.1, but

FreeBSD 12.1 upgrades to 8.0.1. Other Clang/LLVM versions are available

via the system's package manager, including Clang 9.0.

<em id="fn8">8</em>: Our macOS x64 Binaries are compiled with 10.13 as a target.

However there is no guarantee compiling on 10.13 will work as Xcode11 is

required to compile.

| linux-arm64 | CentOS 7 with devtoolset-8 / GCC 8 ^[8](#fn8) |

| linux-ppc64le | CentOS 7 with devtoolset-8 / GCC 8 ^[8](#fn8) |

| linux-s390x | RHEL 7 with devtoolset-8 / GCC 8 ^[8](#fn8) |

| linux-x64 | CentOS 7 with devtoolset-8 / GCC 8 ^[8](#fn8) |

<em id="fn8">8</em>: The Enterprise Linux devtoolset-8 allows us to compile

binaries with GCC 8 but linked to the glibc and libstdc++ versions of the host

platforms (CentOS 7 / RHEL 7). Therefore, binaries produced on these systems

are compatible with glibc >= 2.17 and libstdc++ >= 6.0.20 (`GLIBCXX_3.4.20`).

These are available on distributions natively supporting GCC 4.9, such as

Ubuntu 14.04 and Debian 8.

The current version of Node.js does not support FIPS when statically linking

(the default) with OpenSSL 1.1.1 but for dynamically linking it is possible

to enable FIPS using the configuration flag `--openssl-is-fips`.
