Dependencies MacOS

Xcode

• Xcode>=4.6.3* is required for compilation.

  * If recently upgraded OS make sure your XCode isn't outdated by running open -a XCode, or via Applications.

• Xcode Command Line Utilities* must be activated.

  sudo xcode-select --install
  sudo xcodebuild -license

  *Alternately via Applications, Xcode, Xcode Preferences menu, Downloads tab, Command Line Tools, Install. Or if that's missing, hunt down the installer from Apple Downloads.

Homebrew

• Homebrew* or an equivelent package manager is required for fetching libraries

  ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  *Alternately, you may use MacPorts instead.

  brew install git cmake pkgconfig fftw libogg libvorbis lame libsndfile libsamplerate jack \
  fluid-synth sdl2 libgig libsoundio stk portaudio node fltk qt5 glib

  * If you're building 1.2.x or older, also install sdl12-compat(formerly sdl).

  And the dmg packaging utility

  npm install -g appdmg

Troubleshooting

Namespace Errors

- include/QtCore/qglobal.h:675:70: error: no template named 'is_arithmetic_v' in namespace 'std'; did you mean 'is_arithmetic'?

Check to make sure only qt5 is installed, the build system may be getting headers from another Qt version.

Library Loading Issues

export DYLD_PRINT_LIBRARIES=1
/Applications/LMMS.app/Contents/MacOS/lmms  # or build/LMMS.app/Contents/MacOS/lmms
