If you checked out this project from the subversion repository you must run './bootstrap' to initialize the build system. Now do './configure' to create the Makefiles. Optionally you can run configure with '--enable-debug', which will turn on debug options. If you want to disable debugging options do './configure CXXFLAGS=""', needed since autoconf defaults to adding debug flags to the compiler.

Issue 'make' to compile the project.

Optionally you can do 'make check' to run test programs. 'make doc' will generate documentation.

'make install' will install the package into 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

quiet nan

Quiet NaN's must be supported.

BLAS

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

GSL

GNU Scientific Library, GSL ​http://www.gnu.org/software/gsl/.

Optional packages

ATLAS

GSL supplies a reference implementation of BLAS. You may want to consider using hardware optimized BLAS. The ATLAS (​http://math-atlas.sourceforge.net/) 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. 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="/usr/lib64/atlas" ./configure
