fatal error: 'cairo.h' file not found

Hello,

I have an Electron app that uses pdfjs-dist. On Mac OSX, the app was working perfectly. But I had to use a new computer with OSX Ventura 13.4.1 (the latest Apple os).

When simply installing pdfjs-dist, not even importing nor using it, the app can't compile and crashes immediately. The error is:

› Package 'gobject-2.0' requires 'libffi >= 3.0.0' but version of libffi is 2.1

I have browsed your github issues, and I have installed every related packages that might be needed with brew: pkg-config, cairo , pango, libpng, jpeg, giflib, librsvg, libffi. The computer has Node 18.16.1.

Configuration:

• Operating system and its version: OSX 13.4.1 (Ventura)
• PDF.js version: 3.8.162

I know the issue talks about Electron, BUT, the crash happens when simply installing pdfjs-dist, so the issue definitely comes from here. Also, canvas is marked as an optionalDependenciesof pdfjs-dist. Maybe I need to install an additional package?

Thank you!

The problem is that the canvas dependency is being built from source instead of using the prebuilt version, which does appear to be available at https://github.com/Automattic/node-canvas/releases (it should be
canvas-v2.11.2-node-v108-darwin-unknown-x64.tar.gz given that Node 18.16.1 corresponds to ABI version 108 according to https://nodejs.org/en/download/releases). If you have M1, maybe it has something to do with Automattic/node-canvas#2253 and Automattic/node-canvas#2036 not being implemented yet upstream.

In any case, what I think you're missing is libcairo2-dev (see https://packages.debian.org/sid/libcairo2-dev, not sure what the OSX alternative is given that I only use Linux) since that contains the development header files; usually those are separate from the regular cairo package.

Hopefully this helps, but otherwise the question is better asked upsteam in the canvas bug tracker at https://github.com/Automattic/node-canvas since we don't know more about it here.
