Audacity releases for Windows are currently built with Microsoft Visual
Studio 2013 C++. Most of us use the Express edition, which is free.
For instructions on compiling Audacity under the Cygwin
UNIX Emulation Layer, see the "Compiling Audacity under
Cygwin" section below. This is not maintained.
Note that Audacity uses VC++'s multithreaded DLL runtime libraries.
If you have MSVC installed, these are in your PATH, but users to
whom you distribute your builds may not have them, so you may have
to distribute them, as described for the wxWidgets DLLs, below.

MSVC++ STEP 3: Build wxWidgets
------------------------------------------------------------------------
Before you can start the build process, you must update the
project settings to tell Visual C++ where to find wxWidgets.
There are three settings that need changing:
3.1. Include Directory (e.g., "C:\wxWidgets-2.8.12\include")
3.2. Resource Directory (e.g., "C:\wxWidgets-2.8.12\include")
3.3. Library Directory (e.g., "C:\wxWidgets-2.8.12\lib")
Fortunately, this is parameterized, using a Windows
environment variable, WXWIN. There are various ways to set
these, so look in the Windows help system.
In the Audacity project file, there are declarations like
$(WXWIN)\include
that get interpreted as, e.g., "C:\wxWidgets-2.8.12\include".
The typical setting for WXWIN is "C:\wxWidgets-2.8.12".
For example,
set WXWIN =C:\wxWidgets-2.8.12
3.1. Open "C:\wxWidgets-2.8.12\build\msw\wx_dll.dsw" with
Microsoft Visual Studio.
Make sure to use wx_dll.dsw, not wx.dsw, because wx.dsw
does not have the correct dependencies for the DLL builds.
When you open wx_dll.dsw, Visual Studio will prompt whether
to convert. Click "Yes To All". Next time you open a Visual
Studio session, you can avoid this prompt by opening
"C\wxWidgets-2.8.12\build\msw\wx_dll.sln" instead of wx_dll.dsw.
Once you have set the WXWIN environment variable correctly,
the Audacity project file's declarations will do the rest.
3.2. If you want to use the wxWidgets accessibility features, we have
modified one of the wxWidgets files. Rather than provide a patch,
we store the modified file in the Audacity code repository, and you
can replace the corresponding wxWidgets file. You will need to
download Audacity (next step) to get these.
Note that you must restart the Audacity solution (sln)
file so it picks up changes in the environment variables.
In "audacity\win\wxWidgets_additions" is one .h file.
You may want to make a backup of the wxWidgets original of it,
in "C:\wxWidgets-2.8.12\include\wx\msw\setup.h",
e.g., by renaming it "setup.h.bak" before copying the replacement,
in case you also build without these accessibility features.
In some cases, you may need to reboot the computer to ensure
the variables are read correctly.
Copy "audacity\win\wxWidgets_additions\setup.h" to
"C:\wxWidgets-3.0.2\include\wx\msw\setup.h".
Audacity releases are built with these accessibility features.
3.3. Build wxWidgets for all configurations of Audacity that you want.
* Build "DLL Unicode Release" to use in a "Release"
version of Audacity.
With VS2013 you will get an error for missing pbt.h header, you can (apparently safely) comment t
See "MSVC++ STEP 6: Build Audacity" for the differences
between these versions of Audacity.

But it may not on VS2013 so you will have to make sure to build these as well:
* wxexpat
* wxjpeg
* wxpng
* wxregex
* wxtiff
* wxzlib

wxbase28*_odbc*.* dbgrid.

MSVC++ STEP 4: Set wxWidgets location for Audacity
------------------------------------------------------------------------
4.1. Locally installed help is optional, but required for a full Release
The Audacity Visual Studio project has been set up to use enviornment
variables to locate all externally referenced SDKs. For wxWidgets, it
uses the "WXWIN" environment variable.
Before you can build Audacity, you must set the variable. This process
can vary depending on the version of Windows you're using. The following
is based on Windows 7, so you may need to make adjustments.
4.1. Open the "Control Panel"
4.2. Click the "System" app
4.3. Click the "Advanced system settings" link
4.4. On the "Advanced" tab, click the "Envirnment Variables..." button
4.5. Click "New..." in the "System variables" group
4.6. Set the "Variable name" to "WXWIN" (without the quotes)
4.7. Set the "Variable value" to the full path of where you installed
wxWidgets (typically c:\wxWidgets-2.8.12)
4.8. Click "Ok" until you exit the "System Properties" app
Once you have set the WXWIN environment variable correctly, the Audacity
Project file's declarations will do the rest.
Note that if you currently have the Audacity Solution open in Visual
Studio, you must restart Visual Studio for it to recognize the new
environment variable.
In some cases, you may need to reboot the computer to ensure the
variable it updated.

ASIO (from Steinberg) is a sound card interface protocol that is faster
than standard WMME. Unlike WMME, not all soundcard drivers support it.
Because ASIO is a proprietary, closed standard,
we (or any third party) cannot distribute its SDK.
That means we cannot distribute builds of Audacity that support
ASIO, because Audacity is licensed under the
GPL (http://audacity.sourceforge.net/about/license), which requires
we distribute all source code.

So, although you can build your own copies of Audacity with
ASIO support, for personal use, you cannot distribute them without
violating the Audacity license and the ASIO license.
If you build ASIO support into Audacity, do not distribute that build.

MSVC++ STEP 5: Build wxWidgets

This typically has to be done only once.
5.1. Run Visual C++ and load the Audacity solution, "audacity\win\audacity.sln".
5.2. In the Solution Explorer, right click the "wxWidgets-2.8.12" project and
select "Build".
This will add the Audacity specific configuration to wxWidgets and correct
a minor incompatibility between wxWidgets 2.8.12 and Visual Studio 2013.
It will then build both the Debug and Release versions of wxWidgets.
