How to compile

libopenmpt and openmpt123

  • Autotools

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

    ./configure
    make
    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 64bit x86-64 when building with Visual Studio.
    • 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 winamp.com 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 xmp-sdk.zip into include/xmplay/.

        Please visit un4seen.com to download the SDK. You can disable xmp-openmpt in the solution configuration.

  • Makefile

    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

      make
      

      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):

      Run:

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

      or

      # generates WebAssembly
      make CONFIG=emscripten EMSCRIPTEN_TARGET=wasm
      

      or

      # 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/config-emscripten.mk.

    • DJGPP / DOS

      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
      

      or

      ./build/download_externals.sh    # download liballegro binaries
      make CONFIG=djgpp USE_ALLEGRO42=1 BUNDLED_ALLEGRO42=1
      
    • American Fuzzy Lop:

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

      make CONFIG=afl
      

      For more detailed instructions, read contrib/fuzzing/readme.md.

    • 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.
