How to run on OSX

[xstasi]

Hi!

I know your project is only meant to be supported on Linux, but I got it running on Mac OSX (with m2 architecture!) and I'd like to share how I did it.

Feel free to make of this information what you wish.

1. Install dependencies
   • brew install boost vamp-plugin-sdk
2. Download nnls-chroma plugin
   • git clone https://github.com/c4dm/nnls-chroma; cd nnls-chroma
3. Make the dependencies available in the source tree (edit version accordingly)
   • ln -s /opt/homebrew/Cellar/vamp-plugin-sdk/2.10.0/ vamp
   • ln -s /opt/homebrew/Cellar/boost/1.81.0_1 boost
4. Horribly copy files around to be where the Makefile expects them
   • cp vamp/lib/*a vamp/include/
5. Patch Makefile.osx as follows

diff --git a/Makefile.osx b/Makefile.osx
index d6fa701..46839a3 100644
--- a/Makefile.osx
+++ b/Makefile.osx

-BOOST_ROOT = ../boost_1_48_0
+BOOST_ROOT = boost/include

-ARCHFLAGS ?= -mmacosx-version-min=10.7 -arch x86_64
+ARCHFLAGS ?= -mmacosx-version-min=10.7
 OPTFLAGS  ?= -O3 -ffast-math
 PLUGIN_EXT = .dylib

6. Build and install
   • make -f Makefile.osx
   • mkdir -p ~/Library/Audio/Plug-Ins/Vamp
   • cp nnls-chroma.dylib ~/Library/Audio/Plug-Ins/Vamp

Hope this may save a bit of time and headache to the next person trying to run this :)

Thanks for your work!

Thank you very much, worked like a charm ✅

This worked! Just a reminder though to edit this line ln -s /opt/homebrew/Cellar/boost/1.xx boost to be up-to-date with whatever version of Cellar happens to be current. Thank you!

My setup: MacOS 12.7 / Monterey, Apple Silicon M1 (Macbook Pro), vamp-plugin-sdk 2.10.0, boost 1.84.0 (latest available by brew). I am getting compile errors in the boost library:

• expected '(' for function-style cast or type construction
• expected ';' at end of declaration list
• expected ';' at end of declaration
• C++ requires a type specifier for all declarations

Probably just a compiler flag/setting wrong or missing, but I am lacking the right keywords to google a solution.
By chance anyone here has a good tip for me?
