Hi Harry,
Do you know if there is some rule to compiling using librtaudio? Because,
there is an error..and i don't know what's wrong. I'm using g++ 4.7.2 and
i'm compiling using:
$ g++<programname.cpp> -o <programname>
The error is: undefined reference to 'RtAudio::RtAudio(RtAudio::Api)' i'm
including the lib in the program, normally!

Hi, Harry!
I don't know...hehe...i'm just was searching for api's and alsa seemed to
be a good ideia. But, it's a bit difficult. I'm gonna take a look at this
others api's
Thanks!

Hi Thiago,
Slightly other question: are you *sure* you want to write directly using
the ALSA API?
Generally, writing a JACK[1] client (for linux-pro-audio use-cases), or
RtAudio[2] is a better idea, and easier in my opinion...
They're easier to write to, and abstract away some of the details of the
soundcard settings / channels etc.
HTH, -Harry

function to make the sound capture and i got this input/output error. I
don't get it why this is happening...so, please...some kind soul can help
me?
Thanks

you need to add the library to the linker with the -l option.

And on most distros you might want to use rtaudio-config to find out the
appropriate linker and compiler flags:
LIBS=`rtaudio-config --libs`
CFLAGS=`rtaudio-config --cxxflags`
etc.
And then use these in your compiler invocation/makefile. BTW, hint to
the portaudio developers: there's a rather standard tool for such tasks
called pkg-config. It might be a good idea to supply a portaudio.pc
file instead of/together with the rtaudio-config program.

Rt audio and poet audio are different projects.
For RtAudio, there are 2 CPP files that you compile into your code : no
linking library just yet.
When you want jack / salsa support, you add the appropriate #define, and
link to the libs needed by that output framework. Check the RtAudio page
for details, they have good docs.
