Error with `npm install csound-api`

Thanks for the explanation.  Now I get the problem.  I just installed Csound via Brew, and then I was able to install csound-api via npm.  Success!  Thanks!

I don’t have an M1 Mac on which I can reproduce this, but on Apple Silicon, Homebrew installs into /opt/homebrew rather than /usr/local, so Clang needs to be told where to find Homebrew-installed headers and libraries.

Can you try running—

CPATH="$(brew --prefix)/include" \
LIBRARY_PATH="$(brew --prefix)/lib" \
npm install https://github.com/nwhetsell/csound-api.git

—and if that still results in an error about boost/lockfree/queue.hpp not being found—

export CPATH="$(brew --prefix)/include"
export LIBRARY_PATH="$(brew --prefix)/lib"
npm install https://github.com/nwhetsell/csound-api.git

I’m hoping that one or both of those will resolve the boost/lockfree/queue.hpp error, but I’m willing to bet you’ll end up with an error that csound/cwindow.h isn’t found. Csound’s installers put headers in a non-standard location, and the simplest way to resolve this is to reinstall Csound from Homebrew:

brew install csound

Rerunning one of the above npm install commands should then install csound-api.

Thanks so much for the fast response, Nate! export CPATH="$(brew --prefix)/include" and export LIBRARY_PATH="$(brew --prefix)/lib" did the trick with finding the Boost library. You're also correct that I'm now getting an error due to the cwindow.h header.

I noticed that the Csound headers appear to be installed on my computer at /Library/Frameworks/CsoundLib64.framework/Headers. Would I be able to use the same export CPATH= command to include this directory? If that's a solution I'd prefer to do that over installing another Csound instance via Brew. Otherwise, I can bite the bullet and do what you suggested.

Thanks!

@jasonhallen You’re welcome, happy to help!

Would I be able to use the same export CPATH= command to include this directory?

Yes, but that wouldn’t resolve the issue with Clang being able to find csound/cwindow.h. The problem is that on Linux and Windows, Csound puts headers in a folder named csound, so #include <csound/cwindow.h> works. However, Csound’s macOS installer puts headers in the folder you mention—/Library/Frameworks/CsoundLib64.framework/Headers—so #include <csound/cwindow.h> wouldn’t work even if that folder was added to CPATH (but #include <cwindow.h> would work).

The simplest fix for this—by far—is to install Csound using Homebrew. Csound from Homebrew has everything that the “official” installer includes, plus more (like the opcodes that were relegated to https://github.com/csound/plugins).
