----------------------------------------
Microsoft Visual Studio 2005SP1/2008/10
----------------------------------------
No specific actions are needed to compile WASAPI API under Visual Studio.
You are only required to install min. Windows Vista SDK (v6.0A) prior
compilation.
----------------------------------------
MinGW (GCC 32-bit)/ MinGW64 (GCC 64-bit)
----------------------------------------
To compile under MinGW you are required to include 'mingw-include' directory
which contains necessary files with WASAPI API. These files are modified
in order to be compiled by MinGW compiler. These files are taken from
Windows Vista SDK (v6.0A). MinGW compilation is tested and proved to be
fully working under 32-bit and 64-bit modes.
MinGW (32-bit) tested: gcc version 4.4.0 (GCC)
MinGW64 (64-bit) tested: gcc version 4.4.4 20100226 (prerelease) (GCC)
