BUILDING SILO FROM SOURCE:
==========================

> These instructions apply to an ancient version of Silo shipped as a
> part of VisIt source tree. You should use current [Silo distribution]
> (https://wci.llnl.gov/codes/silo/) instead, also available through
> [MacPorts] (http://www.macports.org/).

1) Download and unpack [Silo source code]
(http://www.sfu.ca/physics/cosmology/defrost/silo/silo060605.sh):

    sh silo060605.sh; cd silo060605

2) If you are using shared HDF5 libraries (e.g. the ones supplied by
Fedora), Silo distribution requires patching (if you have `libhdf5.a`,
you can skip this step). Download and apply [silo-config.patch]
(http://www.sfu.ca/physics/cosmology/defrost/silo/silo-config.patch):

    patch configure.in < silo-config.patch

After patching is done, regenerate configure script:

    autoconf

3) HDF5 calling API changed in version 1.8. If you are building against
new HDF5 libraries, you have to enable compatibility mode by passing
`-D H5_USE_16_API` flag to the compiler. Above patch does it for you.

4) Configure Silo as usual. For example:

    ./configure --prefix=/usr/local --libdir=/usr/local/lib64 \
      --disable-sdx --disable-gui --enable-parallel --without-readline \
      --without-exodus CFLAGS='-Os -march=core2'

5) Build and install Silo:

    make && make install
