Installing gosu on FreeBSD

I'm trying to install this Ruby gem on FreeBSD, and it's failing with the following error:

# gem install gosu
Building native extensions. This could take a while...
ERROR:  Error installing gosu:
        ERROR: Failed to build gem native extension.

    current directory: /usr/local/lib/ruby/gems/2.4/gems/gosu-0.14.5/ext/gosu
/usr/local/bin/ruby24 -I /usr/local/lib/ruby/site_ruby/2.4 -r ./siteconf20190322-6847-x8s25j.rb extconf.rb
The Gosu gem requires some libraries to be installed system-wide.
See the following site for a list:

Other things I tried:

Is it even possible to install it on FreeBSD? Searches didn't return anything useful.

Solution

  • On FreeBSD system headers are organized slightly differently than in Linux.

    Quick man lookup reveals, that you need to

    #include    <sys/types.h>
#include    <sys/stat.h>
#include    <fcntl.h>

    to make these definitions visible.
