These instructions are intended for Linux. On other systems you will have to |
|---|
| 9 |
construct something compatible to build gr-audio-portaudio. |
|---|
| 10 |
|
|---|
| 11 |
In order to use portaudio with gnuradio you will need to download and install |
|---|
| 12 |
a late version of portaudio. Please cd to a directory where the cvs command |
|---|
| 13 |
below will be allowed to build the portaudio directory tree. |
|---|
| 14 |
|
|---|
| 15 |
cvs -d:pserver:anonymous@www.portaudio.com:/home/cvs co -r v19-devel portaudio |
|---|
| 16 |
|
|---|
| 17 |
This will make a directory portaudio unless you already have one. It will |
|---|
| 18 |
check out the Portaudio API version 2 release 1.9. |
|---|
| 19 |
|
|---|
| 20 |
In the directory where this README is found, there is a patch file. Hopefully |
|---|
| 21 |
this patch will not be needed for long. Portaudio is working with us to use |
|---|
| 22 |
auto*, libtool, etc. The patch is autoconfiscate.patch. |
|---|
| 23 |
|
|---|
| 24 |
cd to the portaudio directory and run |
|---|
| 25 |
|
|---|
| 26 |
patch -p0 <autoconfiscate.patch |
|---|
| 27 |
|
|---|
| 28 |
this will modify the portaudio source tree to use standard tools and prepare |
|---|
| 29 |
it for use with gnuradio. Now run |
|---|
| 30 |
|
|---|
| 31 |
chmod u+x bootstrap |
|---|
| 32 |
|
|---|
| 33 |
you may need to edit bootstrap and remove the 2.50 at the end of some of the |
|---|
| 34 |
commands (on SUSE 10.0 for example). |
|---|
| 35 |
|
|---|
| 36 |
./bootstrap |
|---|
| 37 |
|
|---|
| 38 |
./configure --help |
|---|
| 39 |
|
|---|
| 40 |
|
|---|
| 41 |
will reveal the options for configure that are available to you. If you do not |
|---|
| 42 |
understand the options or wish to accept the defaults please just run |
|---|
| 43 |
|
|---|
| 44 |
./configure |
|---|
| 45 |
|
|---|
| 46 |
If you do not want the includes and libraries install in /usr/local (standard) |
|---|
| 47 |
then enter the prefix arguments to ./configure. This document will assume you |
|---|
| 48 |
are doing the standard installation and that will be into /usr/local. |
|---|
| 49 |
|
|---|
| 50 |
On Linux if you have the jack tool available from |
|---|
| 51 |
|
|---|
| 52 |
http://jackit.sourceforge.net |
|---|
| 53 |
|
|---|
| 54 |
the portaudio configure will enable the library to talk to jack. |
|---|
| 55 |
|
|---|
| 56 |
Now you are ready to make the portaudio library. |
|---|
| 57 |
|
|---|
| 58 |
make; sudo make install;sudo ldconfig (possibly /sbin/ldconfig). |
|---|
| 59 |
|
|---|
| 60 |
will make the code and install it into the prefix (/usr/local) selected and |
|---|
| 61 |
will cache the configuration information for other programs to use for their |
|---|
| 62 |
configuration options. |
|---|
| 63 |
|
|---|
| 64 |
Now you are ready to install gr-audio-portaudio. In the gr-build directory |
|---|
| 65 |
you may run |
|---|
| 66 |
|
|---|
| 67 |
cvs co gr-audio-portaudio |
|---|
| 68 |
|
|---|
| 69 |
cd gr-audio-portaudio |
|---|
| 70 |
../buildit |
|---|
| 71 |
|
|---|
| 72 |
will configure, make, and install the portaudio sink and source. |
|---|
| 73 |
|
|---|
| 74 |
In gnuradio-examples/python/audio please test by running |
|---|
| 75 |
|
|---|
| 76 |
./mono_tone_portaudio.py |
|---|
| 77 |
|
|---|
| 78 |
|
|---|
| 79 |
If this runs you are likely in business but this chooses the default device |
|---|
| 80 |
(typically /dev/dsp which is being run by alsa under oss emulation and on a |
|---|
| 81 |
Mac it will choose coreaudio). |
|---|
| 82 |
|
|---|
| 83 |
./mono_tone_portaudio.py -O hw:0,0 |
|---|
| 84 |
|
|---|
| 85 |
chooses the default alsa device. |
|---|
| 86 |
|
|---|
| 87 |
./mono_tone_portaudio.py -O /dev/dsp |
|---|
| 88 |
|
|---|
| 89 |
will force the use of OSS and the default oss device. To run with jack, you |
|---|
| 90 |
will probably enter the following command: |
|---|
| 91 |
|
|---|
| 92 |
./mono_tone_portaudio.py -O alsa_pcm |
|---|
| 93 |
|
|---|
| 94 |
|
|---|
| 95 |
In the portaudio directory, you may list the devices visible to portaudio by |
|---|
| 96 |
searching for and running the command |
|---|
| 97 |
|
|---|
| 98 |
pa_devs |
|---|
| 99 |
|
