OpenLibm
OpenLibm is an effort to have a high quality, portable, standalone
C mathematical library (libm).
It can be used standalone in applications and programming language
implementations.
The project was born out of a need to have a good libm for the
Julia programming langage that worked
consistently across compilers and operating systems, and in 32-bit and
64-bit environments.
Platform support
OpenLibm builds on Linux, Mac OS X, Windows, FreeBSD, OpenBSD, and DragonFly BSD. It builds with both GCC and clang. Although largely tested and widely used on the x86 and x86-64 architectures, OpenLibm also supports arm, aarch64, ppc64le, and mips.
Build instructions
- Use GNU Make to build OpenLibm. This is
makeon most systems, butgmakeon BSDs. - Use
make USEGCC=1to build with GCC. This is the default on Linux and Windows. - Use
make USECLANG=1to build with clang. This is the default on OS X, FreeBSD, and OpenBSD. - Architectures are auto-detected. Use
make ARCH=i386to force a build for i386. Other supported architectures are i486, i586, and i686. GCC 4.8 is the minimum requirement for correct codegen on older 32-bit architectures.
