Dependencies

libopenmpt

• Supported compilers for building libopenmpt:
  • Microsoft Visual Studio 2017 or higher, running on a x86-64 build system (other target systems are supported)
  • GCC 5.1 or higher
  • Clang 3.8 or higher
  • MinGW-W64 5.1 or higher (it is recommended to preferably use posix threading model as opposed to win32 threading model, or at least have mingw-std-threads available otherwise)
  • emscripten 1.38.5 or higher
  • DJGPP GCC 7.2 or higher

  • any other C++14 compliant compiler (full standard compliant mode is known to work with GCC >= 5.1 and Clang >= 3.8)

    libopenmpt makes the following assumptions about the C++ implementation used for building:

    • std::numeric_limits<unsigned char>::digits == 8 (enforced by static_assert)
    • sizeof(char) == 1 (enforced by static_assert)
    • existence of std::uintptr_t (enforced by static_assert)
    • sizeof(float) == 4 (enforced by static_assert)
    • sizeof(double) == 8 (enforced by static_assert)
    • wchar_t encoding is either UTF-16 or UTF-32 (implicitly assumed)
    • representation of basic source character set is ASCII (implicitly assumed)
    • representation of basic source character set is identical in char and wchar_t (implicitly assumed)
    • libopenmpt also has experimental support for platforms without wchar_t support like DJGPP

    libopenmpt does not rely on any specific implementation defined or undefined behaviour (if it does, that's a bug in libopenmpt). In particular:

    • char can be signed or unsigned
    • shifting signed values is implementation defined
    • signed integer overflow is undefined
    • float and double can be non-IEEE754
• Required compilers to use libopenmpt:
  • Any C89 / C99 / C11 compatible compiler should work with the C API as long as a C99 compatible stdint.h is available.
  • Any C++11 / C++14 / C++17 compatible compiler should work with the C++ API.
• J2B support requires an inflate (deflate decompression) implementation:
  • zlib
  • miniz can be used internally if no zlib is available.
• Built-in MO3 support requires:
  • libmpg123 >= 1.14.0
  • libogg
  • libvorbis
  • libvorbisfile
  • Instead of libmpg123, minimp3 by Lion (github.com/lieff) can be used internally to decode MP3 samples.
  • Instead of libogg, libvorbis and libvorbisfile, stb_vorbis can be used internally to decode Vorbis samples.
• Building on Unix-like systems requires:
  • GNU make
  • pkg-config
• The Autotools-based build system requires:
  • pkg-config 0.24 or higher
  • zlib
  • doxygen

openmpt123

• Supported compilers for building openmpt123:
  • Microsoft Visual Studio 2017 or higher, running on a x86-64 build system (other target systems are supported)
  • GCC 5.1 or higher
  • Clang 3.8 or higher
  • MinGW-W64 5.1 or higher
  • DJGPP GCC 7.2 or higher
  • any C++14 compliant compiler
• Live sound output requires one of:
  • PulseAudio
  • SDL 2
  • SDL 1.2
  • PortAudio v19
  • Win32
  • liballegro 4.2 on DJGPP/DOS

Optional dependencies

libopenmpt

• Character set conversion can use one of:
  • Win32
  • iconv
  • C++11 codecvt_utf8 instead of the internal conversion tables and functions.
• doxygen 1.8 or higher is required to build the documentation.

openmpt123

• Rendering to PCM files can use:
  • FLAC 1.2 or higher
  • libsndfile
  • Win32 for WAVE
  • raw PCM has no external dependencies
• help2man is required to build the documentation.

Source packages

Building the source packages additionally requires:

• 7z (7-zip)
• autoconf
• autoconf-archive
• automake
• gzip
• help2man
• libtool
• subversion
• tar
• xpath (libxml-xpath-perl)
• zip
