Setting up a Windows Builder

Environment

First set MIXXX_X to either x64 or x86.

SET MIXXX_X=x86
SET MIXXX_X=x64

Then, run this snippet:

SET WINDOWS_SDK_VERSION=7.1
SET MIXXX_LIB_BASE=C:\Mixxx\lib\1.12
SET MIXXX_LIB=%MIXXX_LIB_BASE%\%MIXXX_X%\
"C:\Program Files\Microsoft SDKs\Windows\v%WINDOWS_SDK_VERSION%\Bin\SetEnv.cmd" /xp /release /%MIXXX_X%
"%DXSDK_DIR%\Utilities\Bin\dx_setenv.cmd" %MIXXX_X%
SET MIXXX_VCEXPRESS="c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\VCExpress.exe"

Build Settings

Runtime

Important: Every dependency must be built with the same runtime. The options are:

/MT - multi-threaded static 
/MTd - multi-threaded static debug
/MD - multi-threaded DLL 
/MDd - multi-threaded DLL debug

We use /MD currently. If you do not use the same runtime, then Mixxx will have seemingly random segfaults on some Windows platforms and you will hate your life.

Static vs. Dynamic Libraries

You can choose whether to build dependencies as static libraries (.lib files) or dynamic libraries (.dll files). Static libraries don't need to be distributed with Mixxx – they are baked into mixxx.exe. Another advantage is you don't have to deal with Windows “DLL hell” as much.

Release vs. Debug

Release configurations of libraries often build with the most efficient settings and strip debug information out of the library. This is good for performance but bad for debuggability.

The important thing is that if you cannot mix release and debug libraries since they often use the debug or release runtime. Some libraries provide a “release-with-debug-info” option. This is preferable since providing debug symbols in a binary comes at no performance cost and a slight size increase. The upshot of this is that stacktraces from Windows users will come with more information and stack frames filled in.

FFTW3

Use version 3.2.2 with VS2008 build files.

chromaprint

chromaprint 0.7

cmake . -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DWITH_FFTW3=ON -DFFTW3_DIR:STRING=%MIXXX_LIB% -DCMAKE_INSTALL_PREFIX:STRING=%MIXXX_LIB%
nmake /f Makefile
COPY .\src\chromaprint.lib %MIXXX_LIB%
COPY .\src\chromaprint_p.lib %MIXXX_LIB%
COPY .\src\chromaprint.h %MIXXX_LIB%

rubberband

rubberband 1.8.1

  • Edit Project File:
    • Release → General → Whole Program Optimization → Use Link Time Code Generation
    • Release → C/C++ → Optimization → Whole Program Optimization → Enable link-time code generation
    • Release → C/C++ → Code Generation → Runtime Library → VERIFY /MD IS SELECTED
    • Add to source files: src/kissfft/kiss_fft.c src/kissfft/kiss_fftr.c

For the x64 version of rubberband you need to hand-patch src/float_cast/float_cast.h to remove inline assembly (taken from http://doxygen.reactos.org/dc/de3/float__cast_8h_source.html – the copyright on the file is the same as float_cast.h)

Stick this block before #if (defined (WIN32) || defined (_WIN32)) and change it to #elif.

#if (defined (WIN64) || defined(_WIN64))
#include    <math.h>
#include    <emmintrin.h>
#include    <mmintrin.h>
__inline long int
lrint(double flt)
{
    return _mm_cvtsd_si32(_mm_load_sd(&flt));
}

__inline long int
lrintf(float flt)
{
    return _mm_cvtss_si32(_mm_load_ss(&flt));
}
%MIXXX_VCEXPRESS% rubberband-library.vcproj /project rubberband-library /build Release /useenv 
# Wait until rubberband-library.lib shows up in Release/
COPY .\Release\rubberband-library.lib %MIXXX_LIB%\rubberband.lib
XCOPY /E rubberband %MIXXX_LIB%\rubberband\
