Compiling

1. If you checked out this project from the subversion repository you must run 'bootstrap' to initialize the build system.
2. Issue './configure' to create the Makefiles. Optionally run configure with '--enable-debug', which will turn on debug options.
3. Compile with 'make'.
4. Optionally do 'make check' to run test programs.
5. 'make doc' will generate documentation.
6. Issue 'make install' to install the package on your system. Default installation location is /usr/local, this can be changed with './configure --prefix=/dir/to/install/to'.

If you keep your working copy up to date with the repository you must issue 'autoreconf' in the yat root directory when 'configure.ac' is updated.

Requirements

Except for the obviously needed C++ compiler there are a few packages and programs required for compiling yat and generate supporting material. The configure script will look for required programs and report failure to meet the requirements. Here we list some of the requirements, but omit required standard utilities such as libtool and sed since these are normally available.

Required packages

GSL

GNU Scientific Library, ​GSL version 1.6 or later.

BLAS

A C implementation of Basic Linear Algebra Subprograms (​BLAS) is required. GSL comes with a reference implementation, but you should consider getting a hardware optimized implementation. ATLAS provides optimized BLAS (see below).

quiet nan

Quiet NaN's must be supported.

Optional packages

ATLAS

GSL supplies a reference implementation of BLAS. You may want to consider using hardware optimized BLAS. The ​ATLAS software provides an automatic hardware optimized BLAS library.

The detection of ATLAS is supported by the yat configuration script but in many cases the ATLAS libraries are installed in non-conventional directory locations. As an example, on Fedora 8, ATLAS libraries are located in /usr/lib/atlas or /usr/lib64/atlas depending on your hardware architecture. If you have ATLAS installed and the configure script fails to locate it, try to add the location to the atlas libraries when running configure:

#> LDFLAGS="-L/usr/lib64/atlas" ./configure

Doxygen

​Doxygen is required for generation of the API documentation

Documentation

The API documentation for the latest release is availabe in PDF and HTML and can be found through ​http://trac.thep.lu.se/yat. If you wish to build a local copy, issue make doc and you will find the documents in directory doc/.
