== SLEEF - SIMD Library for Evaluating Elementary Functions
image:http://img.shields.io/badge/DOI-10.1109/TPDS.2019.2960333-blue.svg[TPDS, link=https://ieeexplore.ieee.org/document/8936472]
SLEEF is a library that implements vectorized versions of C standard
math functions. This library also includes DFT subroutines.

== How to build SLEEF
The library itself does not have any additional dependency.
In order to build SLEEF, you need CMake 3.18+, and C and C++ compilers of the same version.
It is also recommended to have the following tools.
* Ninja
* Git
https://github.com/shibatch/tlfloat[TLFloat] is automatically downloaded if no suitable version is found on your system.
Some tests require:
* libssl and libcrypto, that can be provided by installing openssl.
* libm, libgmp and libmpfr
* libfftw.
The build procedure is as follows.
[arabic]
. Check out the source code from our GitHub repository
....
git clone https://github.com/shibatch/sleef
....
[arabic, start=2]
. Make a separate directory to create an out-of-source build
....
cd sleef && mkdir build
....
[arabic, start=3]
. Run cmake to configure the project
....
cmake -S . -B build
....
By default this will generate shared libraries. In order to generate
static libraries, pass option `-DBUILD_SHARED_LIBS=OFF`.
For more verbose output add option `-DSLEEF_SHOW_CONFIG=ON`.
[arabic, start=4]
. Run make to build the project
....
cmake --build build -j --clean-first
....
[arabic, start=5]
. Run tests using ctests
....
ctest --test-dir build -j
....
For more detailed build instructions please refer to
https://sleef.org/compile.xhtml#preliminaries[our web page].
== How to cross-compile SLEEF
For more detailed please refer to
https://sleef.org/compile.xhtml#cross[cross-compile SLEEF]
== Install SLEEF
=== From source
Assuming following instructions were followed.
[arabic, start=6]
. Install to specified directory `<prefix>`
....
cmake --install build --prefix=<prefix>
....
=== Uninstall
In order to uninstall SLEEF library and headers run
....
sudo xargs rm -v < build/install_manifest.txt
....
