Pakkevejledning

Her beskrives hvordan man kommer fra kildekoden til en pakke der kan bruges i installationsvejledningen.

  1. Export source fra repository

    svn export https://merkur.statsbiblioteket.dk/svn/scape-xcorrsound/tags/xcorrSound_v1.01

  2. Kør

    ./createtarball.sh
  3. Nu kan tjærebolden (xcorrSound.tar) distribueres.

Installationsvejledning

Beskrivelse af hvordan man bygger og installerer programmet på en given maskine.

  1. Export XcorrSound

    svn export https://merkur.statsbiblioteket.dk/svn/scape-xcorrsound/tags/xcorrSound_v1.01
  2. Go to the 'xcorrSound/fftw-3-2-2' folder.

  3. Run the following

    ./configure --prefix=<fftw>
make
make install

where <fftw> is the subfolder fftw where xcorrSound_v1.01 was checked out. fx /home/larm/jsn/xcorrSound_v1.01/fftw

  1. go to the 'xcorrSound' folder.

  2. Run

    make xcorrSound

  3. Test that it works: (should print out how to use this tool)

    ./xcorrSound
