Hi,

I'm try to use the deimos portaudio bindings

https://github.com/D-Programming-Deimos/portaudio

I've managed to compile and run the test demo provided with the 
module.
It seems to work fine. However, when I add this statement:

PaStreamParameters outputParameters;

that I need to specify the output parameters for using the
Pa_OpenStream function, rather than the Pa_OpenDefaultStream
function used in the example, I get the following linker error:

dmd pa_test2.d -L-lportaudio
pa_test2.o: In function `_Dmain':
pa_test2.d:(.text._Dmain+0x22): undefined reference to 
`_D6deimos9portaudio18PaStreamParameters6__initZ'
collect2: ld returned 1 exit status
--- errorlevel 1

I'm a newby on D programming and also C programming,
so I'm pretty much lost even after extensive googling.

I'm on Debian Squeeze 64-bit, using the dmd2 compiler.
Any help would be appreciated!

Does the result of calling Pa_GetVersionText() closely match the version  
of the library installed on your computer?

I use Debian as well, and it's not exactly known for speedy updates...
If your version is too old you'll probably have to backport the changes or  
compile a newer version.

(both are relatively easy.)

Did you call the initialization before trying this?

Pa_GetVersionText() gives me:
PortAudio V19-devel (built Nov 25 2010)

the version of the deb for portaudio19-dev is 19+svn20071022-3

so I guess I should try compiling a newer version of portaudio
to use it with d.

I also have a wheezy install and an Ubuntu Precise install, that
probably have newer portaudio versions. Unfortunately when I try
to install portaudio-v19 on those boxes though, synaptic wants to
remove
audacity, ardour and jackd stuff, but I will let it do that
just to see if I can get the d program to compile with the
portaudio
version available there.

Thanks for the help!

The missing symbol is a D symbol. You probably have to compile in
'deimos/portaudio.di', so in your 'dmd yourprogram.d' compile command
add the full path to the di file: 
'dmd yourprogram.d ../path/to/deimos/portaudio.di'

Thanks, that was in fact the problem!
