How to compile

libopenmpt and openmpt123

  • Autotools

    Grab a libopenmpt-VERSION-autotools.tar.gz tarball.

    make check
    sudo make install

    Cross-compilation is generally supported (although only tested for targetting MinGW-w64).

    Note that some MinGW-w64 distributions come with the win32 threading model enabled by default instead of the posix threading model. The win32 threading model lacks proper support for C++11 <thread> and <mutex> as well as thread-safe magic statics. It is recommended to use the posix threading model for libopenmpt for this reason. On Debian, the appropriate configure command is ./configure --host=x86_64-w64-mingw32 CC=x86_64-w64-mingw32-gcc-posix CXX=x86_64-w64-mingw32-g++-posix for 64bit, or ./configure --host=i686-w64-mingw32 CC=i686-w64-mingw32-gcc-posix CXX=i686-w64-mingw32-g++-posix for 32bit. Other MinGW-w64 distributions may differ.

  • Visual Studio:
    • You will find solutions for Visual Studio in the matching build/vsVERSIONwinWINDOWSVERSION/ folder. Minimal projects that target Windows 10 UWP are available in build/vsVERSIONuwp/. Most projects are supported with any of the mentioned Visual Studio verions, with the following exceptions:
      • in_openmpt: Requires Visual Studio with MFC.
      • xmp-openmpt: Requires Visual Studio with MFC.
    • libopenmpt requires the compile host system to be amd64 or ARM64 when building with Visual Studio.
    • In order to build libopenmpt for Windows XP, the Visual Studio 2017 XP targetting toolset as well as the Windows 8.1 SDK need to be installed. The SDK is optionally included with Visual Studio 2017, but must be separately installed with later Visual Studio versions.

      The Windows 8.1 SDK is available from or directly from

  • You will need the Winamp 5 SDK and the XMPlay SDK if you want to compile the plugins for these 2 players. They can be downloaded automatically on Windows 7 or later by just running the build/download_externals.cmd script.

    If you do not want to or cannot use this script, you may follow these manual steps instead:

    • Winamp 5 SDK:

      To build libopenmpt as a winamp input plugin, copy the contents of WA5.55_SDK.exe to include/winamp/.

      Please visit to download the SDK. You can disable in_openmpt in the solution configuration.

    • XMPlay SDK:

      To build libopenmpt with XMPlay input plugin support, copy the contents of into include/xmplay/.

      Please visit to download the SDK. You can disable xmp-openmpt in the solution configuration.


The makefile supports different build environments and targets via the CONFIG= parameter directly to the make invocation. Use make CONFIG=$newconfig clean when switching between different configs because the makefile cleans only intermediates and target that are active for the current config and no configuration state is kept around across invocations.

  • native build:

    Simply run


    which will try to guess the compiler based on your operating system.

  • gcc or clang (on Unix-like systems, including Mac OS X with MacPorts, and Haiku (32-bit Hybrid and 64-bit)):

    The Makefile requires pkg-config for native builds. For sound output in openmpt123, PortAudio or SDL is required. openmpt123 can optionally use libflac and libsndfile to render PCM files to disk.

    When you want to use gcc, run:

    make CONFIG=gcc

    When you want to use clang, it is recommended to do:

    make CONFIG=clang
  • mingw-w64:
    make CONFIG=mingw64-win32    # for win32
    make CONFIG=mingw64-win64    # for win64
  • emscripten (on Unix-like systems):


    # generates WebAssembly with JavaScript fallback
    make CONFIG=emscripten EMSCRIPTEN_TARGET=all


    # generates WebAssembly
    make CONFIG=emscripten EMSCRIPTEN_TARGET=wasm


    # generates JavaScript with compatibility for older VMs
    make CONFIG=emscripten EMSCRIPTEN_TARGET=js

    Running the test suite on the command line is also supported by using node.js. Depending on how your distribution calls the node.js binary, you might have to edit build/make/


    Cross-compilation from Linux systems is supported with DJGPP GCC via

    make CONFIG=djgpp

    openmpt123 can use liballegro 4.2 for sound output on DJGPP/DOS. liballegro can either be installed system-wide in the DJGPP environment or downloaded into the libopenmpt source tree.

    make CONFIG=djgpp USE_ALLEGRO42=1    # use installed liballegro


    ./build/    # download liballegro source
  • American Fuzzy Lop:

    To compile libopenmpt with fuzzing instrumentation for afl-fuzz, run:

    make CONFIG=afl

    For more detailed instructions, read contrib/fuzzing/

  • other compilers:

    To compile libopenmpt with other compliant compilers, run:

    make CONFIG=generic

The Makefile supports some customizations. You might want to read the top which should get you some possible make settings, like e.g. make DYNLINK=0 or similar. Cross compiling or different compiler would best be implemented via new config-*.mk files.

The Makefile also supports building doxygen documentation by using

make doc

Binaries and documentation can be installed systen-wide with

make PREFIX=/yourprefix install
make PREFIX=/yourprefix install-doc

Some systems (i.e. Linux) require running

sudo ldconfig

in order for the system linker to be able to pick up newly installed libraries.

PREFIX defaults to /usr/local. A DESTDIR= parameter is also supported.
