WASAPI build question

Hi all,

I just tried to compile portaudio for WASAPI under Win7 with MSVC, which I have not been using at all before.
The obvious error is that it tries to compile for DSound. So, the question is: How can I *explicitly* build
for WASAPI ? Also it would be great to have the WIKI updated. Is anyone in charge of that ? If not I would be
interested to work on that.

Best and thanks in advance

ASIO: CoInitialize fails mysteriously

Hello list


I'm working with PortAudio for the first time, and have run into a problem trying to load ASIO drivers. 

Specifically, when loading an ASIO device, the code reaches line 1006 of pa_asio.cpp (in LoadAsioDriver( ), current SVN repo), where there is a line:

CoInitialize( 0 );

I have set a break point here: the call to CoInitialize( ) fails in gdb with a code of -2147417833 (meaning: call context cannot be accessed after call completed). Anyway, the control flow then returns to the previous method, instead of trying to call asioHostApi->asioDrivers->loadDriver(). So it looks like CoInitialize is failing catastrophically somehow.

I am guessing that this might have something to do with iasiothiscallresolver.cpp (which I am including in my build). 

(I'm building a QT application in mingw, and linking PortAudio statically, but I've tried building PortAudio as a .lib and .dll in VS++ 8 too, same result). 

I know CoInitialize is an old PortAudio problem, but any help you can give me on this would be really appreciated. 

Rob

Re: WASAPI build question

Hi Alexander,

I ran MSVC from the path \build\msvc\portaudio.sln. In the source tree I can 
see pa_win_wasapi.c file included and when I am building PA I am getting 
pa_win_wasapi.c file compiled as well. DirectSound is being compiled as 
well, as well as WMME, ASIO. If you wish to compile only WASAPI then you 
need to tweak project settings as following:

1) add such defines in project settings:
PA_NO_WMME
PA_NO_DS
PA_NO_ASIO

2) disable compilation of WMME, DS, ASIO implementation files by deleting 
them from project tree or disabling it (MSVC allows to disable compilation 
on source code file basis)

As to Wiki I can't help much, probably Phil Burk or Ross Bencina could 
provide info on that.

Best regards,
Dmitry.

Re: WASAPI build question

For the case of Eclipse you shall include needed files manually, e.g. create 
your own Eclipse project with similar settings (defines, includes) similar 
to project for MSVC for example. I do not remember whether Eclipse supports 
project import from Makefile which you can fine tune then.

Dmitry.

Re: ASIO: CoInitialize fails mysteriously

Hi Rob,
 
What about DirectSound or WASAPI APIs, they also utilize call to CoInitialize. Do they operate ok for you? Is it only ASIO failing with exception? For me ASIO works ok, but if you are using MinGW then you are obliged to include into compilation this file - 'iasiothiscallresolver.cpp' which resolves difficulties with correct calling convention, although for MSVC it is not required.
 
Best regards,
Dmitry.

Thanks Dmitry ! Actually, I am preparing portaudio to be installed on a number of Win7-machines in a
university pool and it appears that the problems I mentioned might be related to administrative
restrictions. The fact that I am not that familiar with the Windows-world does not improve the situation
... I need to work on this.

I will possibly get back on this topic later -
Best regards

Re: ASIO: CoInitialize fails mysteriously

Hi Dmitry,


Thanks for the reply. Eventually I tried rebooting my machine and it all works fine now. It is a long time since I've developed on a Windows box, one forgets that this type of thing is necessary.

I would still like to know why the call to CoInitialize( ) was making the method return early, but perhaps this is a mystery destined never to be solved.

best
Rob
