CMake Build Instructions

Build requirements

CMake: needs v3.6 or later

Git: optional, for version numbers

GCC / Make

MSVC / Visual Studio

If building the CLI for *nix-based OSes, vgmstream123 also needs the following:

  • LibAO

If building for *nix-based OSes, the following libraries are optional:

  • libmpg123
  • libvorbis (really libvorbisfile, though)
  • FFmpeg

See BUILD.md's Compilation requirements for more info about various component and installation.

Build directions

It is recommended to do out-of-source builds as opposed to in-source builds. Out-of-source builds have been tested to work, while in-source builds have not been tested at all.

NOTE: The CMake scripts attempt to collect all the source files are configuration time. If you are following vgmstream development through git or adding your own source files, you MUST re-run CMake manually to regenerate the files. Failure to do so can result in either missing functionality or compile errors.

First you will need to run CMake to generate the build setup. You can use either the CMake GUI or run CMake from the command line.

CMake GUI

If you have access to the CMake GUI, you can use that to create your build setup. Select where the source code is (that should be the directory just above this one) and where you wish to build to (preferably a directory outside source).

You may have to add some entries before configuring will succeed. See the CMake Cache Entries section for details on the entries.

Once the entries are in place, you can click on Generate (or Configure then Generate). This should ask you what build system you wish to use. As long as there are no errors, you should see the following at the bottom of the window:

Configuring done
Generating done

Before that you'll see what options are enabled and disabled, what is going to be built and where they will be installed to.

You may need to select a Generator first, depending on your installed tools (for example, Visual Studio 16 2019 or MingW Make on Windows). If you need to change it later, select File > Delete Cache. You may need to include those tools in the Path variable, inside Environment... options.

If you decided to build for a project-based GUI, you can click on Open Project to open that. (NOTE: Only Visual Studio has been tested as a project-based GUI.) If you decided to build for a command line build system, you can open up the command line for the build directory and run your build system.

CMake command line

If you don't have access to the CMake GUI or would prefer to only use the command line, you can run CMake from there. Navigate to the directory you wish to build to and run the following:

cmake -G "<generator>" <options> <path to source code>

Replace <generator> with the CMake generator you wish to use as your build system (for example Unix Makefiles, or don't set for default). Make note of the quotes, and use cmake -h to get a list of generators for your system.

You may have to add some entries before configuring will success. See the CMake Cache Entries section for details on the entries.

Place your entries in the <options> section of the above command, with each option in the form of -D<optionname>:<type>=<value>. Replace <path to source code> with the path where the source code is (that should be the directory just above this one), may need to se -S <path to source> -B <output dir> instead. Example:

git clone https://github.com/vgmstream/vgmstream.git
cd vgmstream
cmake -DUSE_FFMPEG=ON -DBUILD_AUDACIOUS=OFF -S . -B build

You may need to install appropriate packages first (see [BUILD.md)(BUILD.md) for more info), for example:

sudo apt-get update
# basic compilation
sudo apt-get install -y gcc g++ make build-essential 
# extra libs
sudo apt-get install -y libmpg123-dev libvorbis-dev libspeex-dev
# extra libs
sudo apt-get install -y libavformat-dev libavcodec-dev libavutil-dev libswresample-dev
# for vgmstream123 and audacious
sudo apt-get install -y libao-dev audacious-dev
# actual cmake
sudo apt-get install -y cmake

Once you have run the command, as long as there are no errors, you should see the following at the bottom of the window:

Configuring done
Generating done

Before that you'll see what options are enabled and disabled, what is going to be built and where they will be installed to.

You can now run the build system you chose as your generator above, whether that be a command line build system like Unix Make or a project-based GUI like Eclipse.

CMake Cache Entries

The following are the various options and cache entries that you can choose to use when building vgmstream.

If not using a project-based GUI, then you will also need to set what build type you want. This can be set with the CMAKE_BUILD_TYPE option and takes one of the following values:

  • Debug
  • Release
  • RelWithDebInfo: Like Release but with debugging information included
  • MinSizeRel: Like Release but aims for minimum size

Library Options

All of these options are of type BOOL and can be set to either ON or OFF. Most of the details on these libraries can be found in the External Libraries section of BUILD.md.

  • USE_MPEG: Chooses if you wish to use libmpg123 for support of MP1/MP2/MP3. The default is ON.
  • USE_VORBIS: Chooses if you wish to use libvorbis for support of Vorbis. The default is ON.
  • USE_FFMPEG: Chooses if you wish to use FFmpeg for support of many codecs. The default is ON. FFMPEG_PATH can also be given, so it can use official/external SDK instead of the one used in vgmstream project.
  • USE_MAIATRAC3PLUS: Chooses if you wish to use MAIATRAC3+ for support of ATRAC3+. The default is OFF. It is not recommended to enable.
  • USE_G7221: Chooses if you wish to use G7221 for support of ITU-T G.722.1 annex C. The default is ON.
  • USE_G719: Chooses if you wish to use libg719_decode for support ITU-T G.719. The default is ON.

The following options are currently only available for Windows:

  • USE_ATRAC9: Chooses if you wish to use LibAtrac9 for support of ATRAC9. The default is ON.
  • USE_CELT: Chooses if you wish to use libcelt for support of FSB CELT versions 0.6.1 and 0.11.0. The default is ON.
  • USE_SPEEX: Chooses if you wish to use libspeex for support of SPEEX. The default is ON.

Build Options

All of these options are of type BOOL and can be set to either ON or OFF.

  • BUILD_CLI: Chooses if you wish to build the vgmstream CLI program (as well as vgmstream123 on *nix-based OSes). The default is ON.

The following options are only available for Windows:

  • BUILD_FB2K: Chooses if you wish to build the foobar2000 component. Note that this requires FB2K_SDK_PATH and WTL_INCLUDE_PATH to also be given if this option is ON. The default for is ON.
  • BUILD_WINAMP: Chooses if you wish to build the Winamp plugin. The default is ON.
  • BUILD_XMPLAY: Chooses if you wish to build the XMPlay plugin. The default is ON.

The following option is only available for *nix-based OSes:

  • BUILD_AUDACIOUS: Chooses if you wish to build the Audacious plugin. The default is ON.

Paths

All of these paths are of type PATH.

If FDK-AAC/QAAC support is enabled, the following paths are required (with more details in the foobar2000 plugin section of BUILD.md):

If MAIATRAC3+ support is enabled, the following path is required:

  • MAIATRAC3PLUS_PATH: The path to the MAIATRAC3+ library. It is not recommended to use.

The CLI/vgmstream123 programs are normally installed to CMAKE_INSTALL_PREFIX, changing this will change where those are installed.

If building the foobar2000 component, the following paths are required:

  • FB2K_SDK_PATH: The path to the foobar2000 SDK.
  • WTL_INCLUDE_PATH: The path to the include directory of the WTL.
  • FB2K_COMPONENT_INSTALL_PREFIX: The path to the foobar2000 component installation directory. If you want to install the plugin for all users, you could set this to the components directory of the foobar2000 installation. Otherwise you'll want to set this to the user-components directory of your foobar2000 folder within your profile, the location of which depends on your current OS. The component as well as the required DLLs will be installed in this directory.

If building the Winamp plugin, the following path is required:

  • WINAMP_INSTALL_PREFIX: The path to the Winamp installation. The required DLLs will be installed next to winamp.exe and the plugin itself will be installed to the Plugins directory.

If building the XMPlay plugin, the following path is required:

  • XMPLAY_INSTALL_PREFIX: The path to the XMPlay installation. The required DLLs and the plugin will be installed in this directory.

If building the Audacious plugin, no path needs to be given, it will be found by CMake.

Installation

After the above build has been done, the programs and plugins can be installed with CMake as well. For project-based GUIs, running the INSTALL target will install the files. For command line build systems, use the install target.
