Then, I simply used speex_echo_cancellation() function in where i am getting sound. However, I have recently realised that output_frame has been always same without any relation with input_frame and echo_frame. What can be wrong in my project? Any help will be appreciated.

I tried synchronous, asynchronous way of to do that and the only thing I heard was "cazzsdaos?eo?hodg etc" :) I try to use empty array for all parameters in the cancellation function, but the result is always the same ("cazzzursestos?hen etc :)"). What kind of problem may have hear? Any help will be appreciated. Best Regards, Kahya G?ZL?L?K NOTU: Bu mesaj ve ekleri yaln?zca g?nderildi?i ki?i(lere) ?zeldir ve gizlidir.

I get a Windows popup telling me that the test program cannot started because it is missing msvcr12_app.dll (which is ok given the way store apps work), and closing the error and the resulting crash dialog allows configure to complete seemingly normally. When I kick off the make things appear to proceed along for a while with a linking failure at the end of: LINK : fatal error LNK1181: cannot open input file 'cb_search.obj' Nothing really stands out about the building of cb_search.obj... other than the fact there are no obj files anywhere in the directory which makes me suspect that nothing at all was built, yet nothing in the attached big log screams to me as having those kinds of issues. For note, this same MinGW+VS2013 environment and very similar args were able to configure & build libogg just fine earlier... so I'm left puzzled as to what could be wrong here. Any ideas?
