gem slow to install

[codedeleter]

I'm on mac and this gem took me over a minute to install.

% time gem install rugged

It's the "Building native extensions" part that takes up most of the time. I haven't seen many gems take this long to install. Is there any way to get this faster? Is this just my machine? Is it this slow on linux too?

This is configuring and building libgit2 and then rugged. It is bound to take longer than others, as most gems would not build the underlying C library. You can make this faster if you have libgit2 installed on your system by linking against that, but it does require that the versions match.

See

rugged/ext/rugged/extconf.rb

Line 63 in 0f1753d

if arg_config("--use-system-libraries", !!ENV['RUGGED_USE_SYSTEM_LIBRARIES'])
