Try the following

gem install puma -- --with-cppflags=-I/usr/local/opt/openssl/include
bundle install

You can also specify the gem version, like the following:

gem install puma -v '2.11.3' -- --with-cppflags=-I/usr/local/opt/openssl/include

I'm on El Capitian OSX 10.11.2. When I first did `gem install puma` - it gave me `ERROR: Failed to build gem native extension`. I then tried your send command (with puma version "2.9.1") and it seems to have worked with no errors! (yay!). Please would you be able to explain what this command mean? (I'm curious now as to why this command solves the problem). Thanks for your help!!! – Atlas7 Jan 20 '16 at 14:23
Worked for me on El Capitan, no idea why though. – JoannaFalkowska Mar 31 '16 at 10:07

On El Capitan, run `gem install puma -v '2.11.2' -- --with-opt-dir=/usr/local/opt/openssl`. This works fine for me. – Kevin R. Jun 28 '16 at 14:27

Thanks @mahi, I'm on El Captain and this worked like a charm. Cheers m8! – forkinspace May 25 '18 at 14:52

@Ameen what isn't working? Are you getting the same error as above or a different error? Also note this is for OS X 10.12.4 not Ubuntu. There is a good chance the openssl library is somewhere else in Ubuntu. – Beartech Sep 22 '18 at 00:15

Worked for OSX 10.12.6 (Sierra), `bundle install` is now successful. – xaunlopez Feb 18 '19 at 02:01

Not my answer but this helped me install puma on macos (big sur) since there were warnings when building puma.

The command that I used is this:

gem install puma -- --with-cflags="-Wno-error=implicit-function-declaration"

libssl1.0-dev installing helped to me. Try

apt-get install libssl1.0-dev

and then

Have you tried

DISABLE_SSL=true gem install puma

Specify the version if you have version specific requirement like:

DISABLE_SSL=true gem install puma -v version_number

I had similar issue on OSx El Capitan. In order to fix the issue I had to do:

brew install openssl
brew link --force openssl

This will may trigger a warning and will not work ```Warning: Refusing to link: openssl Linking keg-only openssl means you may end up linking against the insecure, deprecated system OpenSSL while using the headers from Homebrew's openssl. Instead, pass the full include/library paths to your compiler e.g.: -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib``` – hatenine Mar 15 '17 at 10:41

It could be an open ssl error

gem install puma -v 2.11.2 -- --with-opt-dir=/usr/local/opt/openssl

I've run into a similar error under Mac OS X 10.10.

Details in the mkmf.log showed that this was due to:

Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.

Which was caused by the installation of a new version of Xcode. This was easily solved by accepting the Xcode license from Apple:

sudo xcodebuild -license

Hope this might help someone in the future ;-)

When using bundler and homebrew:

$ bundle config build.puma --with-cppflags=-I$(brew --prefix openssl)/include
$ bundle install

The gem is looking for ssl libraries. So we have to provide the path to the lib containing the ssl lib

e.g. /usr/share/openssl

In my case the the ssl lib "libcrypto" was in /usr/local/lib. So let's pass /usr/local to it (excluding lib word).

For gem install

gem install puma -- --with-opt-dir=/usr/local

For bundle install

bundle config build.puma --with-opt-dir=/usr/local
bundle install

notice the name build.puma. where puma is the name of the gem.

The build config command adds the following to ~/.bundle/config

---
BUNDLE_BUILD__PUMA: "--with-opt-dir=/usr/local"

For puma 6.0 and above use the following

PUMA_DISABLE_SSL=1 gem install puma -v "6.2.1"

If you're facing issue with bundle install

Run

export PUMA_DISABLE_SSL=1 

bundle install

Run brew info openssl and follow the instructions there. Do not try to --force link the latest openssl with the one that comes installed with OSX by default. (0.9.8)

Specifically it'll ask you to add the Homebrew version of openssl (should be 1.0.2 as of this date) into your $PATH.
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

Note: Make sure to remove any export PATH lines from the bash_profile, since this line above exports it for you appending the rest of the $PATH variable to the end. To view the bash profile use vi ~/.bash_profile

This fixed the problems for installing ruby gems that require compilation. (Puma in this case)
