1# OpenLibm 2 3[](https://travis-ci.org/JuliaLang/openlibm) 4 5[OpenLibm](http://www.openlibm.org) is an effort to have a high quality, portable, standalone 6C mathematical library ([`libm`](http://en.wikipedia.org/wiki/libm)). 7It can be used standalone in applications and programming language 8implementations. 9 10The project was born out of a need to have a good `libm` for the 11[Julia programming langage](http://www.julialang.org) that worked 12consistently across compilers and operating systems, and in 32-bit and 1364-bit environments. 14 15## Platform support 16 17OpenLibm builds on Linux, Mac OS X, Windows, and FreeBSD. It builds 18with both GCC and clang. Although largely tested on x86, it also 19includes experimental support for ARM. 20 21## Build instructions 22 231. Use `make` to build OpenLibm. 242. Use `make USEGCC=1` to build with GCC. This is the default on 25 Linux and Windows. 263. Use `make USECLANG=1` to build with clang. This is the default on OS X 27 and FreeBSD. 28
