gistfile1.txt

$ brew install libmagic
$ brew link libmagic  (if the link is already created is going to fail, don't worry about that)
$ env ARCHFLAGS="-arch x86_64" gem install ruby-filemagic -- --with-magic-include=/usr/local/include --with-magic-lib=/usr/local/lib/

even after installing libmagic, not able to find the file.

#include <Magick++.h>

Awesome. Thank you!

what is required Mac OS version to install libmagic? I have 10.11 and received the following error when tried $ brew install libmagic:

Error: An exception occurred within a child process:

Thank you very much!

On macOS Big Sur 11.4, I had to do the following instead of the last line above:

gem install ruby-filemagic -v '0.7.2' --source 'https://rubygems.org/' -- --with-magic-include=/opt/homebrew/include --with-magic-lib=/opt/homebrew/lib/

thanks

If folks that come here have issues with the also excellent ruby-filemagic Ruby Gem, there exists ruby-magic Ruby Gem too, which has a bit more active development.

One can install it as a pre-built (native) Ruby Gem or as usual, in which case it should use bundled libmagic (as an alternative for requiring a system-wide or external one present).

gem install ruby-filemagic -v '0.7.2' --source 'https://rubygems.org/' -- --with-magic-include=/opt/homebrew/include --with-magic-lib=/opt/homebrew/lib/

This worked for me, but did not solved the problem.
