On other systems you will have to +construct something compatible to build gr-audio-portaudio. + +In order to use portaudio with gnuradio you will need to download and install +a late version of portaudio. Please cd to a directory where the cvs command +below will be allowed to build the portaudio directory tree. + +cvs -d:pserver:anonymous@www.portaudio.com:/home/cvs co -r v19-devel portaudio + +This will make a directory portaudio unless you already have one. It will +check out the Portaudio API version 2 release 1.9. + +In the directory where this README is found, there is a patch file. Hopefully +this patch will not be needed for long. Portaudio is working with us to use +auto*, libtool, etc. The patch is autoconfiscate.patch. + +cd to the portaudio directory and run + +patch -p0 <autoconfiscate.patch + +this will modify the portaudio source tree to use standard tools and prepare +it for use with gnuradio. Now run + +chmod u+x bootstrap + +you may need to edit bootstrap and remove the 2.50 at the end of some of the +commands (on SUSE 10.0 for example). + +./bootstrap + +./configure --help + + +will reveal the options for configure that are available to you. If you do not +understand the options or wish to accept the defaults please just run + +./configure + +If you do not want the includes and libraries install in /usr/local (standard) +then enter the prefix arguments to ./configure. This document will assume you +are doing the standard installation and that will be into /usr/local. + +On Linux if you have the jack tool available from + +http://jackit.sourceforge.net + +the portaudio configure will enable the library to talk to jack. + +Now you are ready to make the portaudio library. + +make; sudo make install;sudo ldconfig (possibly /sbin/ldconfig). + +will make the code and install it into the prefix (/usr/local) selected and +will cache the configuration information for other programs to use for their +configuration options. + +Now you are ready to install gr-audio-portaudio. In the gr-build directory +you may run + +cvs co gr-audio-portaudio + +cd gr-audio-portaudio +../buildit + +will configure, make, and install the portaudio sink and source. + +In gnuradio-examples/python/audio please test by running + +./mono_tone_portaudio.py + + +If this runs you are likely in business but this chooses the default device +(typically /dev/dsp which is being run by alsa under oss emulation and on a +Mac it will choose coreaudio). + +./mono_tone_portaudio.py -O hw:0,0 + +chooses the default alsa device. + +./mono_tone_portaudio.py -O /dev/dsp + +will force the use of OSS and the default oss device. To run with jack, you +will probably enter the following command: + +./mono_tone_portaudio.py -O alsa_pcm + + +In the portaudio directory, you may list the devices visible to portaudio by +searching for and running the command + +pa_devs + |
