SoDaSignals Simple signal processing classes

To get to doxygen generated documentation that is more detailed
than the following summary, go here

SoDaSignals contains classes that provide:
. an interface to FFTW for complex DFT and IDFT
. a filter class for complex signals
. a digital down converter and up converter

Dependencies

SoDaSignals requires very little in terms of libraries and other
stuff.
. FFTW3: both double and single precision versions. If your
distribution distinguishes between "normal" kits and "devel" kits,
install the "devel" package.
. C++: Any version supporting the C++11 standard

and that's it.

Installing

Just like any other CMake project. For instance, to install the
package in /usr/local ... From this directory

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/local
make
sudo make install

This will install the libraries in /usr/local/lib or lib64 as appropriate
and the include in /usr/local/include/SoDaFormat/Format.hxx

It will also write doxygen output that starts at /usr/local/share/sodaformat/doc/html/index.html

MacOS

Mac users should probably use "/opt/local" as the install prefix. This
will put the library where macports puts other libraries and such.

For reasons I can't fully comprehend, some installations (especially
for MacOS BigSur) have trouble finding the FFTW package with cmake. As
ugly as it is, you can fix this problem like this: (in the build
directory) FFTW3f_DIR=/opt/local/lib/cmake/fftw3 cmake ../
Replace /opt/local/lib/cmake/fftw3 with the directory containing the
file "FFTW3Config.cmake"

Additionally, the macports FFTW3 installation is broken. It is
missing "FFTW3fLibraryDepends.cmake" If you are stuck, you can copy
the file in "cmake/macports_fix/FFTW3LibraryDepends.cmake" to the
directory mentioned above. ("/opt/local....fftw3" or whatever)

Linux

No trouble reported yet

Windows

I have no idea.

Testing and Using it all

Take a look at the CMakeLists.txt file and FilterExample.cxx in the
example directory. If the installation has gone right, then you
should be able to do this from this directory.

cd example
mkdir build
cd build
cmake ../
make
./FilterExample

Did that work?

If so, congratulations. And you can use the "CMakeLists.txt" file in
the example directory as a starting point for including the library in
your own cmake based projects.
