[OpenLibm](http://www.openlibm.org) is an effort to have a high quality, portable, standalone
|
2014-06-20 20:09:44 +02:00
|
|
|
C mathematical library ([`libm`](http://en.wikipedia.org/wiki/libm)).
|
2014-06-22 13:46:23 +02:00
|
|
|
It can be used standalone in applications and programming language
|
2014-12-04 20:14:29 +01:00
|
|
|
implementations.

The project was born out of a need to have a good `libm` for the
|
|
|
|
|
[Julia programming langage](http://www.julialang.org) that worked
|
|
|
|
|
consistently across compilers and operating systems, and in 32-bit and
|
|
|
|
|
64-bit environments.

OpenLibm builds on Linux, Mac OS X, Windows, and FreeBSD. It builds
|
|
|
|
|
with both GCC and clang. Although largely tested on x86, it also
|
|
|
|
|
includes experimental support for ARM.

2014-06-22 13:46:23 +02:00
|
|
|
1. `make` or `make USEGCC=1` to build with GCC. This is the default on
|
2014-12-04 20:14:29 +01:00
|
|
|
Linux and Windows.
|
2015-02-01 14:36:16 +01:00
|
|
|
2. `make USECLANG=1` to build with clang. This is the default on OS X
|
|
|
|
|
and FreeBSD.
