Building environment requirements

• GNU Make or BSD make.
• A C99 compiler. Some platform-specific codes may use GNU C extensions; in that case, GCC 3.3+ or a compatible C compiler will be required.

Supported target platforms

Linux-based operating systems

A minimal of Linux 2.0 is required; while version 2.6 or later is recommended.

For GNU/Linux, GNU C Library 2.0 and later versions are supported.

For uC/Linux, only the uClibc 0.9.33.2 is supported.

For Android/Linux, Android 4.0 and later versions are supported.

Linux with other C library will likely work, but not tested.

kFreeBSD-based operating systems

A minimal of kFreeBSD 5.0 is required.

FreeBSD 5 and later releases are supported.

For GNU/kFreeBSD, only the GNU C Library 2.13 is tested and therefore supported.

DragonFly BSD

DragonFly BSD 5.0 and later releases are supported.

macOS (Mac OS X)

Mac OS X 10.4 and later releases are supported.

OpenBSD

OpenBSD 5.0 and later releases are supported.

Solaris

Solaris 9 and later releases are supported.

Currently only tested with GCC, therefore building with Sun C compiler is not supported.

Other Solars-kernel-based operating systems such as GNU/kOpenSolaris are currently not supported.

GNU/Hurd

Currently only tested with GNU C Library 2.19, GNU HURD 0.5 and GNU Mach 1.4. Although unsupported, it is expected to work with newer versions of operating system components.

AIX

Tested on AIX 6.1, AIX 7.1 and AIX 7.2. Although unsupported, it is expected to work on newer versions of the operating system.

Haiku

Haiku R1/alpha4 and later releases are supported.

Cygwin

Currently only tested on Cygwin 1.7.18.

Interix

Support is incomplete, many features won't work.

Interix 3.5 and later versions are supported.
