History:How to Build Picard for Windows

How to build Picard for Windows

Disclaimer

This HowTo is work in progress and terribly incomplete. Currently it is more a collection of notes which can help you to build Picard on Windows, but it is not a real step by step instruction.

About

This HowTo explains the process of building the Picard installer for Windows from source using the MinGW build environment.

Requirements

Runtime & libraries

• Python 2.7.x (Ensure you get a 32-bit version)
• PyQt 4 Picard 0.15 is packaged with 4.7 but Py2.7-x86-gpl-4.8.4 appears to work. Ensure you get a 32-bit/x86 version.
• Mutagen (1.20 works fine)
• libdiscid
• LibOFA

• FFmpeg (Only 0.5.2-w32 currently appears to work; you may need to build it yourself using MinGW/MSYS)
• MinGW & MSYS (Can use the GUI installer to install both at once)

For packaging/installer

• NSIS
• py2exe

Install MinGW and MSYS

Grab one of the installers from here. In the installer ensure you choose the following optional components:

• C++ compiler
• MSYS Basic System
• MinGW Developer Toolkit

Installing to C:\MinGW (MSYS will be in C:\MinGW\msys\1.0) will simplify the rest of the guide.

Build libavformat/libavcodec

Download the FFmpeg 0.5.2 source code and extract it to a directory. You are trying to build individual FFmpeg components in shared mode. Picard needs

• libavformat
• libavcodec
• libavutil

From inside the MSYS shell change to that directory and run:

./configure --prefix=C:/MinGW \
  --extra-cflags="-mno-cygwin -mms-bitfields" \
  --extra-ldflags="-Wl,--add-stdcall-alias" \

  --enable-decoder=pcm_u16be \
  --enable-decoder=pcm_u16le \
  --enable-decoder=pcm_u24be \
  --enable-decoder=pcm_u24le

Build the libraries with

make

You may see errors from make regarding

make: lib: Command not found

Make is looking for the Microsoft Library Manager from Visual Studio. You can ignore these; the DLLs should be successfully built and appear to be sufficient. However you will have to change the build.cfg before building Picard (see below).

Download the Picard source code

See Picard Download for instructions on how to obtain the source code of Picard.

Install Mutagen

From a cmd shell

cd mutagen-1.20
python setup.py install

Build the Picard installer

From a cmd shell, configure Picard:

python setup.py config --compiler mingw32 --library-dirs C:\MinGW\lib --include-dirs C:\MinGW\include

Fix the build.cfg:

[directshow]
libs = 
cflags = 

[libofa]
libs = 
cflags = 

[avcodec]
libs = avcodec.dll avformat.dll avutil.dll
cflags = 

[build]
have-make = True
with-directshow = False
with-avcodec = True
with-libofa = False

Build Picard and create the installer:

python setup.py build --compiler mingw32 
python setup.py build --compiler mingw32 bdist_nsis

Known issues

• It is possible that the resulting picard.exe does not show the proper file icon. This is probably a bug of py2exe on Vista. You can fix the icon with the tool Resource Hacker or any other tool, that can edit the resources in executables.
• If you try to build libdiscid yourself you must apply the patch from ticket #5255.
