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

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.

1. Check out the source code from our GitHub repository

git clone https://github.com/shibatch/sleef

2. Make a separate directory to create an out-of-source build

cd sleef && mkdir build

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.

4. Run make to build the project

cmake --build build -j --clean-first

5. Run tests using ctests

ctest --test-dir build -j

For more detailed build instructions please refer to the dedicated section on CMake or to our web page.
