Building PortAudio with ASIO support
------------------------------------
To build PortAudio with ASIO support you need to compile and link with
pa_asio.c, and files from the ASIO SDK (see below), along with the common
files from src/common/ and platform specific files from src/os/win/ (for Win32)
or src/os/mac/ (for Macintosh).
PortAudio files from src/common/ and platform specific files from
src/os/win/ (for Win32).
If you are compiling with a non-Microsoft compiler on Windows, also
compile and link with iasiothiscallresolver.cpp (see below for
an explanation).
For some platforms (MingW, possibly Mac), you may simply
For some platforms (MingW, Cygwin/MingW), you may simply
be able to type:
./configure --with-host_os=mingw --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
make
./configure --with-host_os=darwin --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
make
and life will be good. Make sure you update the above with the correct local
path to the ASIO SDK.
For Microsoft Visual C++ there is an build tutorial here:

and life will be good.
Obtaining the ASIO SDK

In order to build PortAudio with ASIO support, you need to download
the ASIO SDK (version 2.0) from Steinberg. Steinberg makes the ASIO

SDK available to anyone free of charge, however they do not permit its
source code to be distributed.

Building the ASIO SDK on Macintosh
----------------------------------
To build the ASIO SDK on Macintosh you need to compile and link with the
following files from the ASIO SDK:
host/asiodrivers.cpp
host/mac/asioshlib.cpp
host/mac/codefragements.cpp
You may also need to adjust your include paths to support inclusion of
header files from the above directories.

often fail during initialization. Below is a patch that you can apply.
