I was able to successfully install with:

C_INCLUDE_PATH=$(brew --prefix libexif)/include gem install exif

but when I try to import and use the library I get this error:

I'm using Apple silicon locally (Apple M2 Max)

I also tried cloning this repo and running the load_file benchmark:

ruby load_file.rb

Any ideas?

I ran into this too, to build the native extension I had to specify both the include the CFLAGS and the LDFLAGS:

gem install exif -- --with-cflags="-I$(brew --prefix libexif)/include" --with-ldflags="-L$(brew --prefix libexif)/lib"

Alternatively you could install pkg-config:

brew install pkg-config

and this will configure the compilation flags automatically.
