[ as root ]
% make install # Install ODR-DabMod
+Configure options
+=================
+The configure script can be launch with a variety of options:
+
+ --enable-input-zeromq Enable ZeroMQ input (to be used with ODR-DabMux)
+ --enable-output-uhd Includes the binding to the UHD driver for USRPs
+
+You have the choice between two FFT libraries: KISS FFT and FFTW. KISS FFT is a
+proven library, but it's performance is worse than with the new FFTW. With the
+default KISS FFT, you have the choice between using the normal version, or the
+SIMD accelerated version, which is a bit faster. The corresponding options are:
+
+ --enable-fftw Use FFTW3 instead of KISS FFT (experimental, better performance)
+ --enable-fft-simd Enable SIMD instructions for KISS FFT
+
+Debugging options: You should disable debug to improve ODR-DabMod performance.
+By default, debug is enabled.
+ --disable-debug Do not compile with debugging, and enable optimisations
+ --enable-trace Create debugging files for each DSP block for data analysis
+
+For more information, call:

+ % ./configure --help

Nearly as simple install procedure using repository:
====================================================
* Download and install fec as above
* Clone the git repository
* Bootstrap autotools:
+ % ./bootstrap.sh
+ In case this fails, try one of the following:
% aclocal && automake --gnu --add-missing && autoconf
or
% autoreconf
- whichever works best
* Then use ./configure as above
