# Installation¶

## Prerequisites¶

The SFFT library was only tested on Linux systems and is only guaranteed to work there. However, the library should also be able to compile on other platforms and operating systems.

The following packages have to be installed to compile the library:

If you want to build benchmark tools, also install

The SFFT library is known to work the following compilers:

## Compiling From Source and Installation¶

Unpack the tarball and change into the newly created directory (sfft-version). Then, the SFFT library can be built with a simple:

$./configure$ make

and installed with:

$make install Some configuration options can be passed to the configuration script. The most important are: $ ./configure --help

[...]
--debug               compile in debug mode
--profile             add source-level profiling to instruction counting programs
--without-ipp         do not the Intel Performance Primitives library
[...]

Use --debug and --profile are only useful when developing (see Development). The option --without-ipp is to be used when you do not have Intel IPP installed.

When these steps succeded, you should be ready to use the SFFT library.

## Linking against the SFFT Library¶

Two versions of the SFFT library are built when compiling the sourcecode: a static library (libsfft.a) and a shared library (libsfft.so). You can link these libraries in your programs like any other library, but you have to make sure that you link dependencies as well.
